  2. Gm didn't offer a 3-speed that would stand up to the torque rating of the higher HP V-8s. So they chose a Dearborn"FORD" trans. All the more reason to order a 4 speed. BTW Most Chevy V-8s of that era didn't need a Heavy Duty trans Whats that tell ya??? Muncie did make a 3 speed but it was light duty. Saginaw was the norm for all other 3-speed applications.

    the dearborn transmission was a heavy duty 3 speed option in the BOP GM cars that was sincronized in all 3 gears. I think GM's first 3 speed sincro trans was in 1968??

    1966. I used one in a 55 Poncho way back in '67 or so.

    The first time I saw a Ford transmission in a Pontiac was in 1968. I was working in a gas station and was doing an oil change on a 1967 GTO. When I went to pull the side plug on the 3-speed transmission to check the fluid level I noticed it was a Top Loader Ford. Later that night I told my buddies what I had seen and no one believed me.

    That 3-speed Ford trans was really tough. Because it wasn't as cool as a 4-speed hot rodders mostly ignored it.

    There was also a time when Ford used GM transmissions. '50s Lincolns had Hydra-Matic transmissions. The Lincoln units had a different color ID tag than the ones used in GM cars. Rolls-Royce used Hydra-Matics for a number of years too.
