not sure what its from origanally but I think all were set up as 2wd outputs and then a divorced t-case was used for 4wd.... that said at one time this trans had an advanced adapter and dana18 behind it but I only bought the transmission when I got it. I am not sure what year GM started using them in there trucks but I think around the late 1940's and were used in everything from 1/2ton to school bus size trucks up until 1966 then they came out with the SM465....more info here ........the best advantage is the ultra low 1st gear and the small compact size for short wheelbase it is a real good choice....
