I'm trying to rebuild a 55 pontiac manual transmission. All things considered it might be better to buy another on that works or has enough usable parts to consolidate into one transmission. Who has a transmission or parts for my 55 pontiac
As is often said, a picture would be beneficial. I think that it may be the same as a 5,6 or 7 Chevy but I'm not sure. I'm going to check my Hollander. Pat
he needs 7 more posts until the wanted section of the cl***ifieds is available to him. I looked it up in Hollanders and 55 Trans are all by themself. but it did say that 49-54 Pont trans fits if you change the output shaft and rear ext housing
Sorry to have violated standards. Pull it down if it's bad. My understanding is that the 53 54 will work with mods too. May end up having to go this route if a 55 transmission is not available. Still going to try to find a 55 manual transmission first Thanks for any and all help.
Arn't they the same as Olds and small Buick's internals, just the case is different. It's a selector transmission IIRC.
Hollander interchange number for 55 Pontiac is 491 The interchange section shows 491 fits 55 Pontiac only. But lists that #375 fits by changing the output shaft and extension housing View attachment 6264275
I think on something that year specific id convert to a more common equivalent transmission unless doing a ******** stock resto. Make down the road easier if something happens to the trans again. Even on a stock resto I don't see anyone crawling under it and freaking out if it has a 56 trans
In '56, standard shift Pontiacs got the beefier selector three speed that the Oldsmobiles of the time used. I believe that two of the four mounting holes are the same as the smaller '55 transmission. It wasn't until 1958 that Pontiac went to the common Chevrolet style standard transmission.
