I am swapping a 54 straight 8 into my 51 Catalina. I am assuming that the motor mounts will be the same. What about the Hydramatic transmission? Is the 54 the same as the 51? Will the 51 transmission bolt up to the 54 block? Is the gear shift pattern the same? Thanks.

I can't recall what year the transmissions changed (addition of dual range), but I think 1952.

That is probably why the Hollander Interchange Manual groups 1951 Hydramatic as one listing and 1952-'54 as another.

However, I remember a fellow some time ago who put a newer dual range into his earlier (I think '49). I don't recall if he changed the steering column/indicator or not. But I do recall it was a direct swap.

You would be best advised to contact our Tech Advisor (look in drop down window above) who covers these year Pontiacs... he knows them inside and out! You can also contact our Automatic Transmission Tech Advisor who also knows these older Pontiacs AND their transmissions very well.

BTW, our early Pontiac Tech is in Oakley, IL a couple hours south of you.
