Automatic Transmission Mount Strut Bracket – GM (39079595)

Automatic Transmission Mount Strut Bracket is a compliant mounting element that holds a drivetrain component in place while absorbing movement. The bonded rubber fails from heat and oil long before the metal does.

Replace the Mount Strut Bracket when the bonded rubber is cracked, when fluid has leaked from a hydraulic mount, or when vibration at idle has increased. Check the other mounts before deciding how many to change.

This Mount Strut Bracket is listed as part 39079595 (Transmission Assemblies). Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.

This is GM dealer-sourced stock rather than an equivalent, so the number on the Mount Strut Bracket traces straight back to the manufacturer.
