Tighten
Tighten the transmission control module (TCM) cover nuts to 3 N·m (27 lb in).

7. Install the right side of the cowl cover.

Important: The transmission control module must be reprogrammed when a service replacement module is installed or a DTC 602 will result. (The transmission control replacement module will have a DTC 602 in it from the factory and can only be cleared by reprogramming it with the correct calibration)

8. Install the right end of the hood seal.

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 Adapt Function .
