Transmission Adaptive Functions
General
If the automatic transmission or Transmission Control Module
(TCM) is replaced, the Transmission Control Module (TCM) software
is overwritten and the basic settings must be reset. This is done
on a long test drive when the automatic transmission is warm by
changing through all gears several times while "D" is engaged.
After the long test drive, it may be possible that the Transmission
Control Module (TCM) might not be completely finished with the
running-in process. Thus, the customer must be informed that until
the running-in process is complete, the transmission may not change
gears or operate optimally. Until the running-in process is
complete, there could be hard, jerky gearchanges, increased engine
speed during gearchanges and delayed gearchanges.
