this was like a three speed transmission with an extra "low gear", you drove it like a three speed, pulling out in second gear, fourth gear ratio was 1:1, it is not an overdrive transmission. you only used 1st for creeping or pulling where you needed maximum power. it's similar to the SM465 that came along later. with the right bellhousing it will bolt up to any chevy V8
