Transmission Control Module (TCM): Installation

Carefully inspect the TCM and the transaxle bore for debris or damage. Clean and/or repair as needed.
NOTE: Use a small amount of transmission fluid on the new O-rings prior to installation.

Install new O-rings if the TCM is being reused.

NOTE: Do not force the TCM onto the transaxle or damage may occur.

NOTE: Make sure the TCM sits flush on the transaxle or damage can occur.

Install the TCM on the transaxle. Apply light pressure to seat the O-rings. If the TCM does not push in place with light pressure, remove the TCM and slightly turn the TCM gears and retry installing the TCM on the transaxle.
