You will definately need the Torque Drive Kit and the upgraded hard parts, check out Transmission Head, Mad Dog or Bowtie Overdrive Transmissions. Their sites have a bunches of information. I rebuilt my 700 before all the upgraded parts came out. If I had it to do agian I would just buy one. It was a great learning experience, but now I will have to spend more money to step up to the next level i.e. TOrque Drive, billet servos, better frictions, kolene steels, also the Beast sun shell. When I built mine I spent $750 with a new 2200 stall converter. If I was to buy it outright it would of cost about $1000at that time. The trans I need now is only about $1500. The Torque Drive Kit brings the torque carrying ability up to at least 600lbft. Pretty impressive.
