Callout Component Name
1 Transmission Control Module (TCM)

Procedure 

  • Disconnect the TCM electrical connector.
  • The TCM must be programmed when replaced. Refer to PROGRAMMING AND SETUP .

Tip 

  • Twisting or tilting of the transmission control module electrical connector while disconnecting may result in bent or misaligned electrical terminal pins.
  • It is recommended that transmission adaptive pressure (TAP) information be reset. Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, The ECM, PCM or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned. Reset the TAP values. Refer to Transmission Adaptive Functions .
