Transmission ID
I have pulled the 3 speed transmission from my 71 GT-37. I was expecting a HD Muncie but instead it's a Saginaw. I know it's original because partial VIN is stamped on the side (VIN is 233371P160219). Also it has 1 ring on input shaft.
Does anyone know how I can determine the 1st and 2nd gear artios on this transmission? PS: engine is 250 HP 350 |

Sure, spin the input shaft when in each gear and count the rotations of the output shaft.

Should be 2.54 - 1st and 1.50 for 2nd gear. (2.63 - reverse)

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
