Automatic Transmission Mount – GM (84284913)

Automatic Transmission Mount 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 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 is listed as part 84284913 (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 Where a number has been superseded, the current reference is the one that ships, so check any supersession note before ordering.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 genuine GM stock, supplied for the Mount with the manufacturer number intact so the reference on the box matches the catalogue.
