today i bought a 91 which was an auto and this is my first auto and i am wanting to build it up to the 500hp range and was wondering what kind of trans build you recomend and should i go ahead and get this done before the motor build. i have heard a bunch of good things about garmon on the cummins forum which i am always on and garmon is highly recomended. i live in north ga so bring it down to the shop is not a big deal just trying to figure it out. thanks ironhead
