- 1). Raise the car with the jack and support it on four jack stands. Place a drain pan underneath the transmission fluid pan and check to see if the pan has a drain plug.
- 2). Disconnect the shift linkage that runs along the driver's side of the transmission pan--disconnect the cable end from the ball stud and then remove the bolts that mount the cable bracket to the transmission--this is needed to access some of the transmission pan bolts.
- 3). Unscrew and remove the drain plug, using a flare-nut wrench, and let the fluid drain into the drain pan.
- 4). Remove the mounting bolts for the transmission pan, using the wrench, then carefully pry off the pan with a flat-head screwdriver. If the pan doesn't have a drain plug, remove all but the corner bolts and then slowly remove the front bolts, so that the fluid drains into the drain pan.
- 5). Pull the transmission filter straight down to remove it from the valve body inside the transmission.
- 1). Clean off all traces of gasket sealant from both the transmission and pan, using solvent and a rag. Dry the surfaces with compressed air.
- 2). Install the new filter in the transmission with a new seal; the seal is often pre-installed on most replacement filters.
- 3). Attach a new gasket onto the flange of the transmission pan, and then install the pan back on the transmission with its bolts. Tighten each bolt a little bit at a time, working around the pan's circumference.
- 4). Reconnect the shift linkage, using its bolts, and connect the cable end to the ball stud.
- 5). Lower the vehicle off the jack stands.
- 6). Fill the transmission with four quarts of Dexron III automatic transmission fluid through the filler tube at the right rear end of the engine compartment. Use a funnel to aid in pouring the fluid.
