Transmission Seal Replacement Cost


transmission leak, transmission seal replacement costTransmission seal replacement cost can vary significantly based on which seal you are replacing and what type of vehicle you have.  Similarly, the cost can increase significantly if you have to drain the transmission fluid from your vehicle because transmission fluid can be costly.  

Most mechanics and repair shops have a standard hourly rate they charge so one way to make sure you’re getting a good deal is to call around to different shops in your area and ask what their hourly charge is.  The lower the shops hourly rate, the lower your repair bill will be for the same repair job. Similarly, shops make money off of the parts they sell so it also can be worth asking them what their parts markup is.  For more information about how auto repair shops estimate repair costs, check out this explanation of auto repair labor rates.

Let’s talk about the different seals that might need to be replaced in your transmission

Transmission Seal Replacement Costs:

From most expensive to least expensive:

  • Input shaft seal
  • Shift housing seal
  • Axle shaft seal
  • Output shaft seal
  • Transmission pan seal

The input shaft seal is the most expensive seal in your transmission to replace because it requires removing the transmission and partial disassembly.  Similarly, on a manual transmission, the shift housing seal is at the top of the transmission so the transmission again has to be removed to replace that seal.

If you’ve got a front-wheel or all-wheel drive car, the most common leak point is the axle shaft seals.  A similar seal on a rear-wheel drive car is the output shaft seal and luckily replacing these seals is less expensive because the transmission doesn’t need to be removed.  In some cases, the transmission fluid doesn’t need to be drained either keeping repair costs very reasonable.

The least expensive seal to replace is the transmission pan seal.  Since the transmission pan is at the bottom of the transmission and is rarely blocked by any other components it can be accessed and replaced very easily making it an inexpensive job.

If the transmission seal replacement cost is too high for your wallet or for the value of your car, consider using BlueDevil Transmission Sealer to restore the seal that is leaking in your transmission keeping your car on the road!

      Replacing transmission seals can be quite costly and will vary based on make, model and year of the vehicle. On the high end, you could be paying anywhere from $1500-$2500 for this type of procedure.

      Thank you!

    Took a three week vacation and my 2009 Silverado 1500 sat in the driveway. Upon my return all my transmission fluid had leaked on the driveway. Recently had an oil change service and I’m sure they would have picked the leaks up if it existed then. Prior to this time, I’ve never had a problem with it and the fluid level was good. Look as though my leak is in the front end of the transmission. Will BlueDevil sealer do the job ?

      Thank you for asking about your Chevy Silverado. The BlueDevil Transmission Sealer is intended for leaks that are seeping or lightly dripping. If you are saying you lost all of the transmission fluid with the vehicle just sitting there, unfortunately, it would not be a good candidate for the product. We recommend bringing the vehicle to a transmission specialist for repair.

      Thank you!
