Automatic Transmission Mount – ACDelco (22866321)

Automatic Transmission Mount locates the engine, transmission or subframe and isolates vibration from the body. Rubber hardness and internal voiding are tuned to a specific powertrain, so a stiffer or softer substitute changes how much noise reaches the cabin.

Replace the Mount when engine movement is visible when the throttle is blipped, when a clunk appears on take-up, or when the rubber has separated from the metal. Replacing one worn mount often shows up the next one.

For this Mount the reference is 22866321, in our Transmission Assemblies range. Compare it with the number on the part you are replacing rather than with a photograph.

This is genuine ACDELCO stock, supplied for the Mount with the manufacturer number intact so the reference on the box matches the catalogue.
