Was a T89B manual transmission used in the 1964-65 buicks?

[Guest john erik]

Hello,

First I would like to thank anyone for any help with a transmission application.

I have a T89 b transmission which I think it is a heavy duty three speed transmission. If you look at the transmission it looks like a T10 and it even has a T10 number on the rear case. I would like to know what this transmission fits. The rear housing also has a date code of 10-12-62. The case number is T89B-1 W.G. and on the side cover says T89B-148 W.G. First I want to know if this transmission was used on any 1964 or 65 Buicks and if so why does the rear housing say 10-12-62. Any help would help me identify this transmission and its orginal application. Thanks so much for any help!
