6. Install the transmission oil pan and filter. Refer to Automatic Transmission Fluid and Filter Replacement (See: Transmission and
Drivetrain/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:
Transmission and Drivetrain/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: Transmission and Drivetrain/Automatic
Transmission/Transaxle/Description and Operation/4L60-E/4L65-E/4L70-E - Automatic Transmission/Transmission Adaptive Functions (TCM)).
