Automatic Transmission Mount – GM (84300510)

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.

The Mount in this listing carries part number 84300510 and sits in the Transmission Assemblies category. The number stamped on the original part is the only reliable cross-reference.

Genuine GM supplied for this Mount, with the engineering number unchanged from the factory reference stamped on the original.
