6. Install the transmission oil pan and filter. Refer to Automatic Transmission Fluid and Filter Replacement (See: Automatic
Transmission/Transaxle/Service and Repair/Removal and Replacement/4L60-E/4L65-E/4L70-E - Automatic Transmission/Automatic
Transmission Fluid and Filter Replacement).
7. Fill the transmission to the proper level with DEXRON(R) VI transmission fluid. Refer to Transmission Fluid Level and Condition Check (See:
Automatic Transmission/Transaxle/Testing and Inspection/Component Tests and General Diagnostics/4L60-E/4L65-E/4L70-E - Automatic
Transmission/Transmission Fluid Level and Condition Check).
Note: 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 engine control module (ECM), powertrain
control module (PCM) or transmission control module (TCM) will need to relearn TAP values. Transmission performance may be affected as new
TAP values are learned.
8. Reset the TAP values. Refer to Transmission Adaptive Functions (TCM) (See: Automatic Transmission/Transaxle/Description and
Operation/4L60-E/4L65-E/4L70-E - Automatic Transmission/Transmission Adaptive Functions (TCM)).
