Removal
1. With the vehicle in NEUTRAL, position it on a hoist.
2. Remove the transmission fluid pan drain plug and drain the transmission.
3. Disconnect the heated oxygen sensor (HO2S) connectors and retaining clip from the RH pan rail and then position the connectors aside.
4. Remove the HO2S connector from the front of the transmission pan rail.
5. NOTE: The transmission fluid pan gasket is reusable; clean and inspect for damage. If not damaged, the gasket should be reused.
Remove the transmission fluid pan screws, gasket and fluid pan.
6. NOTE: Clean the area around the solenoid body connector to prevent contamination.
Disconnect the solenoid body harness electrical connector.
7. Remove the screws and the transmission fluid filter.
8. CAUTION: Do not damage the solenoid body connector pins.
Remove the solenoid body screws and remove the solenoid body by lifting on the body and pushing the connector from the other side of the case.
Installation
1. Install new O-ring seals on the solenoid body connector. Lubricate the O-ring seals with clean automatic transmission fluid.
2. CAUTION: Inspect the transmission case bore to make sure it is free of foreign material and not damaged. If it is damaged, transmission leaks may occur.
Install the solenoid body. Tighten the screws in the sequence shown.
^ Tighten to 8 Nm (71 inch lbs.).
3. CAUTION: Lubricate the fluid filter seals with clean automatic transmission fluid or they may be damaged.
NOTE: Make sure the fluid filter seals are correctly seated on the filter.
Lubricate the seals and install the transmission fluid filter.
^ Tighten to 10 Nm (89 inch lbs.).
4. NOTE: The transmission fluid pan gasket is reusable; clean and inspect for damage. If not damaged, the gasket should be reused.

6. CAUTION: Damage will occur to the solenoid body assembly if the screw is tightened above specification.
NOTE: Always install new O-ring seals on the vehicle harness connector.
NOTE: Clean the area around the connector to prevent contamination of the solenoid body connector.
NOTE: Use petroleum jelly to lubricate the O-ring seals to aid in the installation process.
Install and lubricate new O-ring seals on the transmission connector and connect the connector.
^ Tighten to 5 Nm (44 inch lbs.).
7. Install the HO2S connector from the front of the transmission pan rail.
8. Connect the HO2S connector and install the sensor wire retaining clip to the RH side of the transmission pan rail.
9. Fill the transmission.
