- Install the exhaust crossover. Refer to Exhaust Crossover Pipe Replacement in Engine Exhaust.
- Reset the TAP values. Refer to Adapt Function.
Important: Follow this procedure exactly or the transaxle will have no reverse gear due to the servo pin missing the band.
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.
