REMOVAL
1. Remove transaxle case side cover.





2. Remove oil pump bolts, and oil pump assembly.
3. Remove oil pump shaft.





4. Disconnect wire harness connectors from following components:
- Pressure control solenoid
- 1-2, 2-3 shift solenoids
- TFP switch assembly
- TCC solenoid





5. Remove TFP switch assembly bolts, and remove switch assembly from control valve body. The seven TFP switch O-rings are reusable if not damaged, and should remain with pressure switch assembly.





6. Remove remaining control valve body bolts, and remove control valve body assembly.
