Transmission Control Module (TCM) Quick Learn

WARNING: This page is about a different variant/trim than selected.
NOTE:

The scan tool, for many 8-Speed Transmissions now has a QUICK LEARN or STATIC ADAPTATION (STADA) routine that should be performed if the customer has any shift quality concerns or after any internal repairs are performed on the transmission. If the QUICK LEARN or STATIC ADAPTATION routine is not available on the scan tool for the application you are working on or the shift quality concern is not corrected by performing the QUICK LEARN or STATIC ADAPTATION routine then the TCM ADAPTATION PROCEDURES need to be performed.

QUICK LEARN PROCEDURE 

NOTE:

The QUICK LEARN PROCEDURE requires that the Transmission fluid temperature be at least 55°C (131°F).

  1. Drive the vehicle briefly to ensure all clutches have been engaged at least twice. Keep the engine running throughout the remainder of this procedure.
  2. With the scan tool, activate the RESET ADAPTIVE VALUES routine.
  3. With the scan tool, activate the QUICK LEARN routine and follow the on-screen instructions. This procedure requires about 2-5 minutes to complete.
