13. Fill the transmission to the proper level with DEXRON(R) VI transmission fluid. Refer to Transmission Fluid Level and Condition Check (See:
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 TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.
14. Reset the TAP values. Refer to Transmission Adaptive Functions (TCM) (See: Description and Operation/4L60-E/4L65-E/4L70-E - Automatic
Transmission/Transmission Adaptive Functions (TCM)).
