Sierra 1500 2WD V6-4.3L (2008)
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.
12. 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)) .
