How to Change the Transmission Filter in a Jeep Grand Cherokee

by Jeanene S. Valentine

Changing the transmission filter on your Jeep Grand Cherokee should be part of your annual car maintenance routine. A clogged or dirty transmission filter can reduce oil flow to your transmission, which can cause shifting and performance problems to your engine. Replacing your transmission filter is simple, quick and cost-effective.

Raise the vehicle using a car jack and support it securely with the jack stands.

Place drain pan directly below the transmission.

Remove the front and side transmission pan mounting bolts using the ratchet wrench and proper socket. Only loosen the rear transmission pan bolts.

Pry the transmission pan loose with a screwdriver.

Remove the remaining pan bolts using the ratchet wrench.

Remove the pan cover and gasket with your hands and carefully clean the gasket surface using a shop towel.

Drain the fluid from the transmission pan.

Remove the transmission fluid filter from the transmission valve body and replace with the new filter.

Install new gasket and put the transmission pan in place against the transmission and, working around the pan, tighten each bolt a little at a time until fully tightened with the ratchet.

Lower the vehicle and add the specified amount of transmission fluid into the vehicle's filler tube.

Tip

  • After you have replaced the new transmission fluid, with the transmission in Park and parking brake set, run the engine at a fast idle. Move the gear selector through each gear and back to Neutral. Check the transmission fluid and add more if needed.

Warning

  • Make sure the vehicle engine has completely cooled for several hours before changing the transmission filter.
