ah okay thanks. Idk why but I was looking for all three characters together and skipped right over that one. So basically this trans is not anything to get too excited over. what hard parts do you suggest I replace for this trans to last behind a sbc making about 400hp/tq(I would like to leave room for expansion... maybe a little spray in a future). I know the stator support and sun gear shell is a must. I have also heard that the forward drum can break but I never saw an estimated hp figure on when it will fail. I know ckperformance has a rebuild kit that includes a new forward drum and they rate it for 450hp.
