SERVICE INFORMATION

When replacing 4L30-E automatic transmissions or transmission control modules (TCMs), it is important to order the appropriate replacement parts. Failure to pair the proper TCM or transmission with its proper counterpart can result in poor transmission performance.

This Service Bulletin provides important identification data to ensure that a proper pairing of transmission and TCM is always made. See Fig 1 through Fig 3 for the typical location of the identification plate on both the transmission and TCM. See Fig 1 for the typical location on transmissions and TCMs manufactured by Bosch for 1990-93 MY vehicles. See Fig 2 and Fig 3 for the typical location on transmissions and TCMs manufactured by Delco Electronics for 1994 and 1995-95.5 MY vehicles respectively.
