what is difference between a 4sp and automatic transmission
mounting cushion on a 1965 300hp with automatic.
i have a cushion but dont know if it is for a 4sp or automatic

Re: Automatic transmission

I was under the impression that the mounting cushion was the same for either the Powerglide or the manual transmission, but I could be wrong.

Re: Automatic transmission

The 2133 transmission mount was used on all three '64-'67 transmissions; the part number is usually molded into the rubber portion of the mount.

I have no idea. The GM P&A book shows the same mount for all three transmissions, and so does the 1965 Assembly Manual; LICS has it right, Paragon does not.
