Steps
- Support the vehicle and drain the transmission pan
Raise the vehicle at approved points and support it securely on jack stands. Place a drain pan beneath the transmission, loosen most pan bolts, then lower one edge carefully so fluid drains in a controlled stream.
- Remove the pan and old filter
After the fluid has drained, remove the remaining pan bolts and lower the pan. Disconnect the filter wiring if equipped, then pull the filter from its locating point without spilling trapped fluid.
- Clean the pan and sealing surfaces
Remove the magnet and clean it, then wipe the pan interior. Carefully remove old gasket material from the pan and case without scratching either sealing surface or allowing debris into the transmission.
- Install the new filter and pan gasket
Return the clean magnet to the pan, fit the new gasket, and seat the replacement filter on its locator. Connect the filter wiring, raise the pan into place, and start every bolt by hand before tightening evenly to the vehicle specification.
- Refill and check the transmission fluid
Add the specified fluid through a funnel in measured increments. Start the engine and follow the model's temperature, selector, and dipstick procedure for setting the level, then check the pan seal for leaks.
Check your vehicle’s repair manual for exact specifications and fit.
