tranny slips at high power upgrade?
 

i have a basically stock tranny it slips when i romp on it a bit but the fluid is not burnt. I was just wondering if any one could possiblty know what it is i am planning on getting a triple disk tq and a billet input shaft do you think just this could help it from slipping at about 500 horse to 700 or should i get out put and flex plate to etc.

You are also going to need to upgrade the bands and clutches inside the trans to keep it from slipping.
