Reverse Mode
WARNING: This page is about a different car, the 2003 GMC Sierra, 2003 GMC Cab & Chassis Sierra, 2003 Chevrolet Silverado, and 2003 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
While in Reverse, if the scan tool loses communication, or becomes disconnected, the vehicle may remain in Reverse and could move backward if the wheels have not been securely blocked.
Next the scan tool instructs the driver to select Reverse. Once Reverse is selected, the TCM engages C5 clutch to obtain Reverse and learn C5 clutch volume. The TCM repeats this test until the volume learned for C5 clutch has converged.
After learning C1 and C5 clutch volume, Fast Learn updates the adaptive volume data for all shifts with either C1 or C5 on-coming clutch. This completes the "stationary modes" of Fast learn.
NOTE:
All shifts will be left in "fast" adaptive mode at this point.
