727 Overdrive
What is really needed is an aftermarket auto trans with o.d.
The manual trans guys have it made. lots of 4 5 speed trans--lots of hp clutches but like for autos there isn't any aftermarket trans.
Maybe the auto guys are too hung up on using a trans that has the same name on it as their has.
Wish TCI or somebody would make from the ground up a hp auto trans with different bell housings to fit most v8 motors. And sell the darn thing for $1,000, lol Be cheaper to buy a torque converter too.
