Overdrive th400
I was thinking of getting a 75' vette with the Th400 tranny. I want to use it as a daily driver in the summer and don't like the idea of driving around everywhere with no overdrive killing my gas mileage and wearing the engine out faster. Is it possible to add an overdrive kit to the th400? ( i have seen this done with torqueflite 727's) I could probably just switch the tranny out to a th700r4 but i want the th400 for durability reasons as i plan on tuning the motor up to 400~500 hp.
