The Saginaw three- and four-speed manual transmissions transmitted engine power to the wheels on General Motors non-performance and mid-range performance cars. The transmissions were cast-iron and stamped with an application code.
Both versions of the Saginaw transmission featured the case and extension housing sealed with a seven-bolt cover on the side. The gears were fully synchronized and the synchro rings had 30 teeth. Mounted on the cover was the reverse shift lever.
