T 10 Od
there used to be a kit on the market to use the Heavy duty borg warner W 11 4 planet overdrives on the back of a T 10 4 speed. . I have a Packard 3 speed overdrive in My roadster I built back in the 50's. The packaard has sychro"s on ALL 3 speeds, IS one of the strongest car transmissions ever made and Is Short enought.. I just want to get rid of the old hurst floor shifter I had to modify and need to find a 37 Packard top shift mechanism. I ran a Caddy LaSalle trans for a while, but no overdrive. The caddy didn't shift as well as the packard, but had better gear ratios. With 4.56 gears the front wheels still will come off the ground and the Od makes highway cruzing easier. I bought a Fred Hone kit and put an overdrive on the back of a ford C 6, but had a Hay barn fire , destroyed my tow van I was building the engine and trans for.
