Richmond 4-Speed Super T-10 Transmission

2.43 Ratio Super T10
PN# 1304000070

This new Super T10 is built by us and blueprinted to our specs. Using forged synchro rings, bronze thrust washers,and sealed bearings. This can be used as a replacement Super T10 issued in GM cars from 1975- 1982. The 2.43 1st gear ST10 transmission is ideal for vehicles equipped with 3.73 to 4.56 axle ratios. These make great replacements for standard Muncie 4 speeds. Ask us about how to convert your shifter and clutch. These take a few days to build. We will need your axle ratio and tire size to install the correct speedometer gears.
