Re: 4 speed auto transmission with 389
Hey, along this line I have a project question. I am restoring a 1965 GTO with the stock 389 Tri-power. I have the 2 speed Powerglide but would really like to install a 4 speed automatic, possibly with overdrive. Is there a trans that will bolt or use an available adapter or can you modify a TH400/350 BOP by adding a 4th overdrive? Thanks, Jim
