I just got a 47 Olds with Hydramatic and want to know more about this trans. Ive heard that they were battle proved in ww2 served in Sherman tanks. Is that correct? If thats true they should stand up good. What are the pros and cons of this trans. My hydra slips in reverse but I will change the oil and clean filter and see if thats help. Is there any adjustments to made to take care of this? I appreciate all the help I can get.
They were used in tanks, just not the Shermans, and there were two of them, along with two Cadillac flathead V-12's, I think. They've been used in everything from Nash Ramblers to Rolls Royces. They even put them in Lincoln Continentals for a couple of years (A G.M. manufactured, Detroit transmission, in a FOMOCO product). Yours is a "single" range, not the more desirable "dual" range. Chevrolet and GMC trucks, Caddy, Olds, Pont, Nash, Hudson, Rolls, Lincoln, and probably various forms of heavy equipment. I forget anything? Of course, they were the baseline transmission for a lot of aftermarket racing transmissions, such as B and M, Vitar, C and O, and a host of others. Butch/56sedandelivery
