Welcome John

John
There is a lot of experience here, I'm sure someone can quote #'s and get you the information you seek. Here is what I can contribute, The MM4 came in two options, the first was the T10 or the standard BW 4-speed transmission, then there was the T21 option, this was the close ratio and I believe also known as the 83mm 4-speed. My '81 has the T10, and is fresh after new second gear, main shaft, bearings and synco's.

And Welcome to the Corvette Action Center, The #1 Corvette site on the internet (top 100 Corvette Sites listing). This place has lots of information and the only requirement is TIME to look at it all. Enjoy your ride, and if you have any questions or suggestions please don't be bashful, we're here to make it better... and better ;)
