WARNING: This page is about a different car, the 2013 Ford Fiesta. However, it is still accessible from the selected car via links, so may be relevant.

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: 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.
