The FastLearn (adapt) procedure must be performed. This can be done in one step using a scan tool. If this procedure is not done, the TCM
adaptive values will be at the settings that it learned for the old components. and will be in slow adaptive mode. Under these conditions, it would
take an unacceptably long time for the adaptive values to converge to levels suitable for the new transmission.
Perform the FastLearn procedure. Refer to FastLearn Procedure.
