This is a GM light-duty car transmission used from 1966-1985 model years. It has a cast-iron case and extension housing, and a 7 bolt side cover with reverse shift lever on this side cover. The Saginaw is often mistaken for a Muncie. The Muncie also has a 7 bolt side cover; however, the Muncie reverse lever is found in the extension housing and features an aluminum case.SAGINAW 3 SPEED

There are several gear ratios for the Saginaws. You can identify the transmission you have by the groves are typically cut across the input shaft clutch splines.

 

The Saginaw transmission adapters we manufacture will normally require the installation of a new output shaft.

 

These transmissions are externally shifted and will require shifter components.

 

We make an adapter to mate this transmission to a Jeep Dana 18 or 20 transfer case
