Fr. Buick Posted March 25, 2015 Share Posted March 25, 2015 Yes, but the torque converter will be a bit different, I think, to optimize the performance of a smaller or larger engine. It would "bolt in" though. If it is a runner, bolt it in and run it, and use the time to rebuild your original... Link to comment Share on other sites More sharing options...
old-tank Posted March 25, 2015 Share Posted March 25, 2015 The two transmissions are exactly the same and will be a direct interchange. Only the larger series (50/70...Super/Roadmaster) are different (~1" longer).Willie Link to comment Share on other sites More sharing options...
Joseph P. Indusi Posted March 25, 2015 Share Posted March 25, 2015 In this time frame, once Buick went to V-8 engines for all series, the Dynaflow transmissions were all tha same as Willy says above except for the greater length on the Series 50 and 70 cars due to the use of the larger and longer GM "C" body. In 1953, the series 40 cars with the last of the straight eights had a different torque converter from the other series with the V-8 engines. The torque converters on the straight eights were matched to the torque characteristics of this engine and the same was done for the V-8 engines in the other series. The gearboxes were very similar except for some minor differences as well as the length.Joe, BCA 33493 Link to comment Share on other sites More sharing options...

If one is looking for a replacement and finds the "wrong" one for his/her car they can swap out the output shaft and housing and they are good to go. Might give one more options if looking for what is a pretty rare junkyard find these days... Link to comment Share on other sites More sharing options...

Airy Cat Posted April 1, 2015 Share Posted April 1, 2015 When I restored my '55 Special I used a transmission from a '55 Super and just changed out the output shaft and housing. It worked out great. Link to comment Share on other sites More sharing options...
