lhend50 7 Posted September 30, 2019 What models of Buick have the same transmission as a roadmaster. Also what other years would be the same as a 1940. Thanks in advance Lou Share this post Link to post Share on other sites
Guest Posted October 1, 2019 1939 is cable shift, no interchange. 1941 has different case to accommodate mount change. Other years "fit" but aren't the "same"/correct. Share this post Link to post Share on other sites

Other years "fit" but aren't the "same"/correct. 1941 also had some different gears. The 1941 transmission gears fit various Buicks all the way to and thru 1960. 1939 gas different gears also. 1940 big series is all by itself.

Thanks in advance Lou 1940 60 Century 1940 80 Roadmaster 1940 90 Limited all have the same transmission (for 320ci engine). As posts above, some internal parts are the same as other years. And some internal parts 1940 only What is wrong with your transmission? I have an MS execl file that lists part number vs year/model Share this post Link to post Share on other sites
