Still the basic transmission is the same. I would sure like to know where to find one of the tiwn hydramatics.
I was under the impression that just like with the manual transmissions ie the SM420 it was the same from 1/2 ton up through the largest truck offering. And the reason for them not going too crazy with engine torque and power, and the use of very low rear axle ratios as to not over stress the transmission offerings of that day and so they remained upward and downward compatable.
