My Transmission Will Not Shift!

Automatic TransmissionThe transmission is as necessary in a vehicle as the engine itself.  Imagine leaving your car in first gear and trying to maintain speed on the highway, or start from a dead stop in fifth gear.  Engines that are put in vehicles today are designed to run safely in a very specific range or speeds, or RPMs.  If you’ve ever noticed an area where the numbers turn red on your cars tachometer, it’s an indication of the upper limits of your engines ability to safely spin.  Also, automobile engines are designed to run efficiently in an even narrower window.  Since we all want to be able to operate our vehicles comfortably whether we are going 5 miles per hour in a parking lot, or 70 on the highway, we need a transmission coupled to the engine to turn its relatively low range of operating speeds into the wide range of desired speeds for a car.

The automatic transmission in your car surprisingly shares a lot of similarities with the early transmissions in the Ford Model T.  The backbone of most modern day automatics is still the planetary gear system which was used in the Model T.  Similar to a manual transmission, the teeth of the gears in an automatic transmission are always meshing.  In a manual transmission, when you select a different gear, what you really are doing is coupling a different set of gears to the input and output shafts in the transmission.  The theory is similar for an automatic transmission, but the gears are arranged in a much different way.

transmission not shiftingThe planetary gear set in an automatic transmission is named such because there is one large gear in the middle with smaller gears around it, much like a large sun with planets orbiting it.  There is also a third gear around those called the ring gear.  Different gear ratios are obtained by coupling the sun, the planet, or the ring gears either to the input shaft or the output shaft.  The gears that aren’t coupled to the input or output shaft may be held still, or allowed to rotate freely.  For a more thorough explanation check out: http://auto.howstuffworks.com/automatic-transmission.htm

Most automatic transmissions have two sets of planetary gears in them to accomplish all of the gear ratios needed to be useful in your car.  The difficult part is figuring out how to allow any of the gears in the transmission to be coupled either to the input shaft or the output shaft, be held stationary and be able to spin in either direction.  This is usually accomplished through a series of bands, wet clutches and springs.  These bands and clutches are designed to operate in a wet environment, meaning some lubricant should be present to ensure proper operation.  Also, the control of these devices is usually accomplished by fluid pressure that is controlled by your vehicle’s computer.

Transmission wont shiftThe fluid which creates the pressure to operate the clutches and bands as well as lubricate them is automatic transmission fluid.  If your transmission is running low on transmission fluid, the first symptom is usually a hard shifting condition, meaning your car will jolt forward when it shifts.  With enough fluid loss, your transmission will eventually be stuck in one gear.

The best solution is to add the correct amount of the manufacturer’s recommended transmission fluid along with BlueDevil’s Transmission Sealer.  Rather than struggling through finding the leak and possible expensive repair bills, use BlueDevil Transmission Sealer.  It is guaranteed to revitalize the seals in your transmission to stop any leaks making sure your transmission fluid stays at the proper level and your transmission continues to function properly.

      The best place to start would be to change your transmission fluid and filter and then double check to make sure the fluid level is correct. If you are still experiencing difficulty shifting after changing the fluid and filter then you may want to have your vehicle diagnosed by a transmission specialist.

      Thanks!

        1. Scotty,

          Thanks for your question about your transmission. If you’ve moved the shift lever into “Park” but your vehicle still wants to move forward then it’s possible that your shift linkage simply needs adjustment, or you may have a problem with your parking pin. When you shift most transmissions into park, it pushes a small pin into the gear teeth of your flywheel which is what keeps your car from rolling while the transmission is actually in neutral. If your car still rolls as if it’s in neutral we would recommend checking the linkage from your shift lever to that pin. If your car still moves forward as if it’s in drive then you can start by checking the connection between your shift lever and the gear selector lever on your transmission to make sure everything is moving and connected as it should.

          Thanks again for your question!

      1. I have a Nissan primera and it has this same problem of the rpm running high and the gear not shifting from 1 to 2 and upwards.
        I’ve changed the transmission filter and CVT fluid but it’s still won’t shift upwards.

        1. Nick,

          Thanks for your question about your Nissan Primera. There are some reports of the stepper motor which affects shifting in the CVT failing so it’s possible that is the problem you’re having. Unfortunately, there isn’t much you can do in the way of diagnostics without taking your car into a dealership that has the computer to scan the transmission and figure out what’s going on so you may need to take your car to a dealership to have it tested.

          Thanks again for your question!

        You should never overfill the transmission. If it has already been overfilled you will want to drain or siphon enough transmission fluid out to bring it back to the proper fill range. We recommend doing so prior to driving the vehicle.

        Thank you!

        1. Why would my transmission shift when firsted turned on but not after aboutt 5 minutes of running rattle underneath and wont shift into any gear

          1. Jose-

            The best place to start would be to change your transmission fluid and filter and then double check to make sure the fluid level is at the proper level. Having dirty/old transmission fluid or the fluid level too high or too low can cause the transmission to act up and not work properly.

            If you are still experiencing the same shifting issues after changing the fluid and filter and topping it off to the proper level then you may want to have your vehicle looked at by a transmission specialist.

    2. When car is in drive it does not advance into gear to let the car run smooth it just revvs I only changed the fluid in a saturn ion 3 – 2003

      1. Ronald,

        Thanks for your question about your Saturn Ion. If you’re experiencing this problem right after a fluid change then you most likely have an internal problem with your transmission. Problems after fluid changes usually indicate a clog, a failed internal seal or failed solenoids in your transmission. We would recommend starting by having your vehicle checked out by a Saturn dealership or transmission specialist.

        Thanks again for your question!

    3. I have a 1994 jeep grand Laredo awd automatic transmission an its stuck in gear the shifter reads park but when started it takes off then dies this happened while driving tranny has been leeking had to keep putting fluid in bout every few days started out haven to take off in 1st then switch to drive then while driving it got stuck in gear shifter shows park but when started it takes off will only start in park any Fix’s or ideas ?????

      1. Jeremy-

        Thank you for asking about your Jeep Grand Laredo. Based on your description, it is possible that little metal shavings or other pieces of debris are in the system and causing the gears to become stuck. The fact that you are also losing transmission fluid would play into this issue as well. Having the transmission system flushed and refilled with clean transmission fluid would be a good idea in this case. From there, if the transmission gets back to normal functionality, you may add the BlueDevil Transmission Sealer (http://store.gobdp.com/transmission-sealer-00236/) to help stop your leak. You can expect to see results after about 100-200 miles of driving.

      2. My Kia Rio 2010 will not shift into the last gear, and when I stop the car will start moving slowly until I off the car and on it then it will accelerate faster and I’ve changed the ATF

        1. Limsa,

          Thanks for your question about your 2010 Kia Rio. You mentioned already changing the ATF which is about all you can do without special tools, so that’s a good start. Since you mentioned a change when the car is turned off then restarted it sounds like you might be having an electrical issue like a failed sensor in your transmission. Unfortunately, to check these sensors you would need to connect your car to a specialty scan tool that only a transmission repair shop or Kia dealership would have so you may try that.

      1. Jonathan,

        Thanks for your question about your 1995 Mercury Cougar. One of the only things you can do without special diagnostic tools is to check your transmission fluid level and condition. If the fluid isn’t clean and bright, consider getting a transmission fluid change or flush. If you find a low fluid level, add BlueDevil Transmission Sealer (available here: http://store.gobdp.com/transmission-sealer-00236/) then, top off the transmission fluid and see if that gets things working right again.

    5. My 2002 GMC Envoy will not shift into 2nd gear. I have change the transmission filter, fluid, shift solenoids, fuel filter, spark plugs, electronic fan clutch, and map sensor to no avail. Just brought it to the GMC dealership and they told me when they put it on the tech2 machine that it was missing second gear going directly to third and fourth? Could this be a valve or pressure problem in the transmission or would I need to replace or rebuild the transmission?

      1. Thomas,

        Thanks for your question about your 2002 GMC Envoy. First, if the dealership had your car hooked up to the transmission computer, they should be able to tell you why the transmission is skipping 2nd gear. If the other shifts happen smoothly and as expected out guess would be that the problem is with the transmission control system rather than an internal problem. If a sensor like a speed sensor your shift position sensor isn’t reading correctly, or even if the transmission control module is faulty it could be causing the problems you’re having. The dealership should be able to use their computer to scan the different sensors to see if any are reading out of specification.

        Thanks again for your question!

    6. My 2003 Chevy Avalanche was setting for months until I was able to get some work done to it. Now that the work its complete when trying to drive it, it stays in 1st for longer than it needs then quickly goes to 2nd the right into 3rd. It also will not go into reverse. When I first picked it up from the shop the reverse worked fine. Any help with this would be greatly appreciated.

      1. Adrian-

        Thank you for asking about your Chevy Avalanche. The best place to start would be to flush your transmission, change the fluid along with the filter and then double check to make sure the fluid level is correct. Having dirty/old transmission fluid or the fluid level too high or too low can cause the transmission to act up and not function properly.
        If you are still experiencing the same shifting issues after changing the fluid and filter and topping it off to the proper level then you may want to have your vehicle looked at by a transmission specialist.

  1. Clutch pedal works fine but the stick budge won’t move at all riding down the road 1 day went to 3 gear an then pedal want to flood then stick wood not move no more pedal works fine what you think could be problem before I change plate bearing clutch any ideas

    1. Nadina,

      Thanks for your question. It is possible that your transmission had a significant internal failure cause it to be stuck in gear, but since you mentioned your clutch malfunctioning, our best guess is that there still is a problem with your clutch. If your clutch is not disengaging, it would cause shifting to be difficult, if not impossible. Try checking your clutch slave cylinder for movement when you press the clutch pedal. If you do discover a larger problem like a bad throwout bearing, we would recommend replacing the clutch as well while you have the transmission out of your car.

  2. I have a 2002 Chrysler Concord and I just got a transmission put on my car and its not shifting a what else could it please lead me in a direction so I can get my car fixed.

    1. Chandra,

      Thanks for your question about your 2002 Chrysler Concord. Our first recommendation would be to take you car back to the mechanic that put the transmission in and have them check their work and see if they’ll repair things for free. Assuming the transmission you put in was good it could still be your torque converter or the computer control module for the transmission.

  3. I have a 2000 Chevy Silverado 4.8 liter and it shifts high out of first and second gear…but when it tries to shift out of second into third and 2000 rpm it high revs straight to 6000……do u have any suggestions on what could be my problem…..also there is no check engine light

    1. John,

      Thanks for your question about your Chevy Silverado. The problem you’re having could be due to a bad sensor that inputs into your transmission’s computer like the air flow sensor or the throttle position sensor. You may consider cleaning those sensors and the throttle body or checking them for proper operation. Since your problem only seems to be happening in one gear, it could also be that the band, clutch or shift solenoid for that gear is worn out. To find out if this is that case you would need to take your truck to a Chevy dealership and have the transmission and engine function analyzed in real time with a factory computer.

  4. I have a 2004 Buick Rainier and it will not shift from 2nd to 3rd the RPMs go super high and it sounds horrible. We have noticed that there is fluid now also. How bad is this?

    1. Amanda,

      Thanks for your question about your Buick Rainier. When it comes to an automatic transmission, unfortunately, there isn’t much you can do besides check the transmission fluid level and condition. If you’ve got a low fluid level or the fluid is dark or smells burnt you can try changing the transmission fluid to see if that gets things back to normal. If you check the fluid and don’t find any problems then you’re looking at a trip to the dealership or a transmission specialist. Based on your description your problem could be anything from an internal failure require a full rebuild to a bad shift solenoid, but it will take a specialist to diagnose the problem.

    1. Terrell,

      Thanks for your question about your Chevy 2500. First, you might start with checking with your local chevy dealership to see if your truck might still have a powertrain warranty that would cover the cost of any repairs. You might also check your shift mechanism to make sure that when you’re moving your shifting it is actually moving the shift linkage or if it’s electronic actuated, make sure the sensors are registering the shift.

      Thanks again for your question!

  6. Why All shifts is no response. I change the fluid(ATF) and its run and then suddenly its stop again and no other response in all shifts( DRIVE and REVERSE).

    1. Peping,

      Thanks for your question about your vehicle. Based on your description it sounds like things work properly for a little while after you added transmission fluid, but then suddenly stopped again. If that is the case, we would recommend checking for leaks as a low transmission fluid level could cause your transmission to malfunction in all gears. If you find a leak you can use BlueDevil Transmission Sealer (available here: http://store.gobdp.com/transmission-sealer-00236/) to stop the leak and keep things working properly.

      If you don’t have a leak that is causing the problem then you may have some significant internal damage or failure and should consider taking your vehicle to a transmission specialist.

  7. my friend i have an isuzu trooper 1997 3.2 v6 petrol.. i was driving my car and suddenly he start losing power when i stop or reduce and want to accelerate again,or somotimes it fall down.. but the big problem is that the car just dont accept the D Gear..it accept to reverse,even accept L gear 2 and 3… but when I put D if it dont fall down,and if I trie to run he will just lose power,like the car is being stucked by the brakes,and in the panel it says CHECK TRANSMISSION and ABS … I already put new transmission oil but nothing changed.
    so,as the other gears work well and with power,I hope that maybe I dont need to buy a new transmission..
    because when I turn on the car and I put D he can run 5 meters well till the painel lights turn on one saying CHECK TRANSMISSION and one saying ABS.. since it shows the lights the car start losing power..

    1. Yanud,

      Thanks for your question about your 1997 Isuzu Trooper. If your vehicle is displaying the “check transmission” code then there will be a fault code stored in your vehicle’s computer to help you determine what the problem is. You should be able to get the codes read by a local auto parts store or Isuzu dealership. That code will help you know what components to replace to get your transmission working properly again. Based on your description, and considering the transmission works manually in other gears our guess would be you have a bad speed sensor somewhere in your transmission that causes problems in “Drive”.

  9. I have a 2004 chevrolet monte carlo….the problem is if i disconnect the battery and reconnect the car shifts into drive and then after about a 1minute of so it looses power and will not move it does that in reverse too. So I have to disconnect and reconnect for the car to move…or if the car has been sitting it will go into gear but after a minute the engine idles will not shift

    1. Gordon,

      Thanks for your question about your 2004 Chevy Monte Carlo. Since things work for a few seconds after you reconnect your battery, it seems likely that there is some fault code your transmission is throwing your computer causing things not to work. After you disconnect the battery, the computer resets and things work for a little while. Also, since you mentioned things work if they’ve been sitting it also seems likely that you’ve got some significant internal wear in your transmission so you may be in for a rebuild.

      A good next step would be to take your car to a transmission specialist or a Chevy dealership. They will be able to scan the transmission’s computer for codes and tell you if you’ve got a bad solenoid or something else that could be causing the problem you’re having besides wear. That code will help you know what to replace to see if you can get your transmission working again.

    1. Thomas,

      Thanks for your question about your truck. It sounds like the problem is in your transmission rather than the new engine. The problem could be with the torque converter or even your shift linkage. Make sure your transmission fluid is clean and full and the shift linkage is properly adjusted to see if that can get things to go into gear. If everything is installed correctly from the outside, you may need to check your installation of the torque converter.

      Thank you for asking about your Nissan Serena. Are you noticing a loss of transmission fluid? If so, we recommend using the BlueDevil Transmission Sealer (http://store.gobdp.com/transmission-sealer-00236/) to get the system back to normal functionality. Also, is it a CVT? CVT use very specific fluid, so perhaps having just regular ATF is why you are having this issue. You may want to flush the system and switch to CVT specific fluid for your vehicle.

      Thank you for asking about your Toyota Camry. Have you noticed a loss of transmission fluid? Does the fluid look dirty or like it has debris in it? A lack of fluid or dirty fluid would cause the transmission not to shift properly. We recommend checking for transmission fluid loss, and using BlueDevil Transmission Sealer if the system is low. If the fluid looks dirty, you may want to have a transmission system flush performed and refill it with clean fluid. This should get the transmission shifting properly again.

    1. Brad,

      Thanks for your question about your Chevy 1500. If 2nd gear works normally when you have the truck in drive but won’t go into 2nd when you’re shifting from the gear shift lever then it’s possible that your shift cable is worn out or the connection is loose at the transmission. If your truck won’t go into 2nd gear even when it’s in drive then you might have an internal problem with your transmissions like a clogged line, stuck solenoid or another problem in your valve body.

      Thanks again for your question!

  17. Had a issues yesterday with a 2000 Chrysler Concord LXI with the transmission. No issues at all got to a stop light, when it turned green, slight jerk and nothing, at first thought it may have stalled so dropped into park, shut down and restarted and returned to drive. Still getting nothing RPM goes up, but no movement. Pushed into a parking lot and checked fluids looked good, maybe a tad dirty I thought one time I checked. Noted that in Park the car would roll, could not seem to fully get into last gear on shift. Noticed when really pushing up the RPM in drive the car would shutter some speedometer would climb up post 60 mph, but going no wear and sound like its trying to catch a gear and then level off around 40 mph, drop into park gets a sound of like the gears are trying to catch again (slight grinding) and drops back to 0 mph. Do not see any fluid loss on ground and no real prior warnings as was going 55 MPH prior for a while (15 minutes-45 minutes). Any guesses to what maybe the issues as I know it would be guesses.

    Thanks

    1. Alex-

      Thank you for asking about your Chrysler Concord. Have you noticed a loss of transmission fluid? Based on your description, if the fluid looked dirty, we recommend draining the system and re-filling it with clean transmission fluid. It is also possible metal shavings in the system have restricted flow, not allowing proper shifting into gears. A transmission flush would be recommended if that is the case. If the problems persist, we recommend bringing the vehicle to a transmission specialist for a proper diagnosis.

  18. I have a 2003 Hyundai Accent, I was having trouble shifting, it would go into 2 and 3rd then rev, then it would run with no problems. I checked the fluid it was low and I filled it with fluid. It ran good for 2 – 3 days and then it repeated doing it again. I noticed it was slightly low again and I put more tranny fluid in it and for the next couple days it ran good. I would drive about 10 mile or so working fine come to a stop and cycle would start again. I had problems again yesterday but today it seems to be running normal. transmission fluid is at the correct level. Any advice, check engine light, no burning smell, what could be causing this. Does not look dirty.

      Thank you for asking about your Hyundai Accent. The fact that you are losing transmission fluid would cause the kind of symptoms you are seeing. We recommend using the BlueDevil Transmission Sealer (http://store.gobdp.com/transmission-sealer-00236/). You will be adding one oz. of the product per quart of fluid in the system and should expect to see results after about 100-200 miles of driving.

      Thank you!

      The best place to start would be to change your transmission fluid and filter and then double check to make sure the fluid level is correct. Having dirty/old transmission fluid or the fluid level too high or too low can cause the transmission to act up and not function properly.

      If you are still experiencing the same shifting issues after changing the fluid and filter and topping it off to the proper level then you may want to have your vehicle looked at by a transmission specialist.

      Thank you!

  19. I have a 2003 Toyota Corolla I put it in reverse backed out of the parking place then put it into drive I could tell something was wrong then because my shifter was moving to easy anyway I put it in Drive and it would not move pushed it back into the space put it in park and it started rolling back had to pull the emergency brake

    1. Jean,

      Thanks for your question about your 2003 Toyota Corolla! Our best guess is that the problem is just with your shifter linkage, especially if you haven’t had anything else go wrong with your transmission. When you move the shift lever it pulls a cable that is connected to your transmission and it sounds like that cable is either broken or detached from your shift lever allowing it to be easy to move and keeping the transmission from shifting into gear or even park.

      Thanks again for your question!

  21. Hello so I have a 98 Chevy Silverado and had a little problem which I wasn’t able to drive it since July and it is now October so it’s been sitting I had added a bit of transmission fluid and now that I want to drive it. It won’t shift. I am able to take it out of park but it won’t engage at all.

    1. Carter-

      Thank you for asking about your Chevy Silverado. Was the reason the vehicle was not driven for a few months related to the transmission? How much fluid did you have to add? Please contact our technical support line at 888-863-0426 so that we can get a little better understanding of the vehicle’s condition and be able to make any appropriate recommendations.

  22. Hi I have a 2001 dodge ram 1500, I put a transmission in and forgot to fill the torque converter. So it won’t shift gears. I was wondering if I let it run in park would the transmission fill the torque converter?

    1. Evan,

      Thanks for your question about your Dodge Ram. The transmission fluid pump should quickly fill the torque converter while the transmission is idling in park. You may have to check the level and add fluid to your transmission during that time as well depending on the capacity of the torque converter. It is possible that running the torque converter dry for a short time could cause additional wear so adding fluid to the torque converter before installation is the preferred method.

      Thanks again for your question!

  23. Dr car
    Good morning… I have a toyota corolla 2003 when I start it on it would go off and if restart it would start and if I move the gear from parking to drive or reverse it would go off and I can not drive the car… i have change so many things still same problem… Please help me I am in a state of disarray

    I have done the check light and have fixed all what the check light requested for still having same problem… If by chance it start and I want to change to drive or reverse it the car would go off again immediately and I would start it again and it may not start but if I try again it would start but by changing gear it would not move but go off

    1. Alonge,

      Thanks for your question about your 2003 Toyota Corolla. If your check engine light is off and your car idles normally except when you put it in gear, then the chances are your problem is in your transmission. If your transmission is low on fluid or worn out it could be putting an extra load on your engine causing it to stall. Try checking your transmission fluid level. If it is low, try topping it off and adding BlueDevil Transmission Sealer (available here: http://store.gobdp.com/transmission-sealer-00236/) to stop the leak so you don’t end up with a low fluid level again.

      Thanks again for your question!

  24. Hello, my 2012 Nissan Versa gear moves freely from Park to reverse to Drive but on the dashboard, it shows it is on Neutral N. Any idea on what is wrong?

    1. Emmanuel,

      Thanks for your question about your 2012 Nissan Versa. The lights on the dashboard get a signal from a sensor on your transmission range selector. Since the light stays in neutral from drive to reverse it’s possible the range sensor is simply worn out and not giving the correct signal. Fixing this problem should be as easy as checking the connection to that sensor or replacing the sensor.

      Thanks again for your question!

  25. I have a dodge 1500 V8, When I was leaving my parents house, she would rev really high then jerk into second or third, and this morning i noticed she won’t go past 3rd, and when i slow to a stop she shakes hard and tries to turn off. Not sure what to do?

      The best place to start would be to change your transmission fluid and filter and then double check to make sure the fluid level is correct. Having dirty/old transmission fluid or the fluid level too high or too low can cause the transmission to act up and not function properly.

  28. I changed my dodge sprinter van`s gear box control board number 001 545 53 16 to 001 545 59 16 but since then it doesnt work normal again..It changes gear normal when it cools down but doesnt change when it is hot..I would like to know what it wrong with it..

  29. We have a 2000 Nissan maxima gle and it has started getting stuck in low gear while we are driving down the road. Some opinions say to change the transmission fluid, while others say it could be a solenoid. We don’t want the work to be done of it won’t fix the problem. What direction should we go?

  30. My Nissan Altima 2012 was driving fine and then all the sudden started revving high rpms 3-4 then started making a whining noise.. about 10 minutes later of driving it was becoming harder and harder to keep up with traffic until eventually I couldn’t go over 20 mph. Got home finally and took my mom up the road to let her see what was happening and then eventually it wouldn’t speed up at all! I got home going 10mph and parked it. We changed the trans fluid, it was full but dirty. We started tge car drove up the driveway and it only made a loud whine apon startup but went away quickly. Up the driveway it will not go into 2nd gear. Parked it again. Any ideas?

    1. Kate,

      Thanks for your question about your 2012 Nissan Altima. Great job in changing your transmission fluid as that often can help problems like this. First, if you happened to save the fluid it would be smart to run it through a straining cloth to see if there are any metal particles, brass shavings or clutch friction material in the fluid to help you identify what sort of problem you’re having. Based on your description our guess would be that you’ve got some internal damage in your transmission but the presence of metal in the fluid would help prove that. Besides an internal failure or a shift component, the whining you talked about is an indication of a problem with the fluid pump or torque converter so you may start your search for a problem there. Unfortunately, to inspect either of those components you will need to remove your transmission so you might be better off taking your car to a transmission specialist for a diagnosis.

      Thanks again for your question!

  31. I have a 2011 Chrysler 200 that has a problem shifting. It shifted fine one morning as I went to work but that evening as I left I noticed that it shifted once when I left the parking lot but after that it had a problem shifting and going over 40-45mph. The issue seems to come and go as it pleases as this has happened before, then stopped happening, then started happening again. Could this possibly be a minor repair?

  32. I have a 1996 Dodge ram 1500.8 cly.i backed out of drive,took off and noticed it wouldn’t go into 2nd gear..took it to Oriellys.they ran a code on it.said it was saying speed sensor A.They said that would not cause it to not change gears.my friend is a mechanic and he says it can cause it not to change.what do you suggest?
    Vickie Martin

    1. Vickie-

      Thank you for asking about your Dodge Ram 1500. Based on what the mechanic told you, it sounds as though the speed sensor needs to be replaced. Have the sensor replaced, and then verify that your transmission fluid is topped off to the proper level. That should correct the issue and make sure the transmission is shifting properly.

      Thank you!

  34. Hi,

    My 2006 cadillac dts will not shift after approx 15 mph it goes in reverse etc and always shifted smoothly.This happened all at once and i checked the Tranny level and everything seems ok however it is due for a transmission filter and fluid change.I have heard about a sensor that could be the issue and was wondering if anyone has any feedback?Thanks

    1. Philip,

      Thanks for your question about your Cadillac DTS. It is possible you do have a bad sensor that is causing the problem with our transmission. If your car has a separate speed sensor for your speedometer as it does for your transmission and the transmission speed sensor is bad, that could be causing the problem. A bad throttle position sensor may also cause a problem like you’re having. Also, if you’ve got a bad shift solenoid it could also be causing your transmission not to shift. To really understand why your transmission is acting the way it is you would need to have it plugged into a special computer to read the sensor outputs and commanded gear for the transmission. A transmission specialty shop or Cadillac dealership would have the correct computer so our recommendation would be to bring your car to them for a diagnosis.

      Thanks again for your question!

  35. Hello Folks

    I have a Nissan Maxima 2002. lately I’ve been experiencing a problem with shifting. My car drives for about 30 mins or so and when it gets hot, it stops shifting. When I press the gas pedal the engine revs but it doesn’t make the car move faster. I had a check engine light on. I got it diagnosed. The diagnosis came up with P0720 error code. This is a transmission output speed sensor problem. I got this replaced and then got the error codes reset. the check engine light went away. However I still have the problem. I particularly notice when I turn on the AC or drive for a distance of 20-30 miles. When this happens, my option is to shut everything down and wait for things to cool down. When the car is cool down, it works fine.

    Anyone has any thoughts or seen this type of a problem

    1. Steve-

      Thank you for asking about your Nissan Maxima. The best place to start would be to flush your transmission, change the dirty fluid along with the filter and then double check to make sure the fluid level is correct. Having dirty/old transmission fluid or the fluid level too high or too low can cause the transmission to act up and not function properly.

  37. guys I charge my computer box and is using auto gearbox so is possible that I must programme the gearbox to make my car to back to normal.. plz help me guys

    1. Musa,

      Thanks for your question about your transmission. It is possible that you would need up update the software on your transmission computer if you’ve changed your engine computer based on the make and model of your car. Most likely, only a dealership would have the programmer able to perform that function.

      Thanks again for your question!
