REVERSE Mode
WARNING: This page is about a different variant/trim than selected.
CAUTION:
Block the wheels before selecting REVERSE. While in REVERSE, if the Scan Tool loses communication or becomes disconnected, the vehicle could move backward. Failure to block the wheels could result in personal injury or property damage.
Next, the scan tool instructs the driver to select REVERSE. Once REVERSE is selected, the TCM engages the low and reverse clutch to obtain REVERSE and to learn the low and reverse clutch volume. The TCM repeats this test until the volume learned for the low and reverse clutch has converged.
IMPORTANT:
All shifts will be left in fast adaptive mode at this point.
After learning the 1-2-3-4 and the low and reverse clutch volume, FastLearn updates the adaptive volume data for all shifts with either the 1-2-3-4 or the low and reverse on-coming clutch.
