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 shall be done during a long test-drive when the automatic transmission is warm by shifting between all gears several times while "D" is engaged. After test-driving it is possible that the TCM-module is not completely done with the run-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.
