We carry the complete line of Richmond Gear Super T10 transmissions and parts. All new transmissions are built with the same level of care and detail as we do with our Muncie 4 speeds. We only sell OEM replacement component parts and gears for the Super T10. The Super T10 was originally manufactured by Borg Warner then sold to Doug Nash Corporation in the early 1980's and then to Richmond Gear which today is now a division of Midwest Truck. The complete line has been retooled to increase quality and precision. Factory GM Super T10 4 speeds came in 1975 to 1982 Corvettes and 1975 to 1981 Camaro and Firebirds. Variations of the transmission were coupled to overdrives in 1984 to 1988 Corvettes and issued with a 27 spline output in the 1982 Camaro / Firebird platform. Some parts will interchange with 1st design Ford , Studabaker, and AMC versions.
