### Transmission Final Test and Inspection

Complete the following procedure after the transmission is installed in the vehicle:

2. Start the engine and listen for abnormal conditions.
3. While the engine continues to idle, raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
4. Inspect for fluid leaks while the engine is idling.
5. Perform a final inspection for the proper fluid level.
6. Lower the vehicle.
7. Perform final inspection for fluid level
8. Road Test

Important: It is recommended that transmission adaptive pressure (TAP) information be reset.

Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, the ECM, PCM, or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.
9. Reset the TAP values. Refer to Transmission Adaptive Functions .
10. Road test the vehicle.
