Having a slipping transmission can be a frustrating thing. You’ve been driving your car for a while now and you’ve come to expect it to shift a certain way. It’s comfortable and you’re a better driver because you can predict when your car will shift and how it will feel. It’s a very strange feeling when you go to pass someone on the freeway or take off from a stop light and when your car shifts you feel your engine rev up but your vehicle doesn’t accelerate like it usually does. This can be caused by a slipping transmission.
Your transmission may be slipping for a variety of reasons. A slipping transmission is a lot like having a worn out clutch in your vehicle with a manual transmission. In an automatic transmission there are a variety of clutches, brakes and bands that engage, disengage and hold stationary certain parts of the gear set to change the ratios. These clutches, brakes and bands are activated by hydraulic pressure created by the fluid pump in your transmission that pressurizes the automatic transmission fluid.
Your transmission may by slipping for one of two reasons. First, the components in your transmission may be overly worn causing them to literally slip when they are trying to make gear changes. This can cause erratic shifting, or allow your engine to over rev as it changes gears. The components in your transmission may have become worn from normal driving. As these components operate, they will wear down with normal use, but there a few ways you can help them to last a little longer. First, change your transmission fluid regularly. This will make sure there aren’t suspended particles in the high pressure fluid that can be abrasive and wear down components prematurely. Also, when your vehicle is cold, operate your engine at a lower RPM by driving slower. Automatic transmission fluid does a better job lubricating things when it is warm so keeping engine speeds to a minimum while your transmission is still cold can help it last longer. Also, if your vehicle has a performance shift option, it can accelerate wear of the shift components as it causes the transmission to operate at high pressures and make harder shifts, so only use it when necessary.
The other possible cause of your transmission feeling like its slipping would be due to low fluid pressure. If the fluid that operates the shifting mechanisms is low for some reason it can cause your transmission to not fully engage and feel like it is slipping. Low fluid pressure may be due to bad fluid pumps, clogged transmission filters or a low transmission fluid level. On many vehicles you can check your transmission fluid level through a dip stick in your engine bay. Your transmission dip stick will look a lot like your oil dipstick but should be marked as “TRANS” or be red in color. The transmission dip stick is often at the rear of the engine bay near the firewall. If you discover your transmission fluid is low you should top it off with the manufacturer’s recommended type of transmission fluid. Also, your low transmission fluid level is due to a leak which should be fixed before you lose any more transmission fluid. You can quickly and easily seal any transmission fluid leak by adding BlueDevil Transmission Sealer to your transmission Fluid. BlueDevil Transmission Sealer will quickly and permanently seal the leaks in your transmission by restoring the seals and gaskets to their original condition.
