I have a th400 with reverse manual trans-brake valve body in my Vega.I already know I built the clutch stacks too tight (10-20 thousandths per stack),because when you wing it to 4-5000 in neutral,the car lurches forward,kinda like the forward clutch is too tight.My question,if you haven't guessed,is what would be a good baseline clutch stack clearance for each set in the trans? I'm simply gonna dis-assemble the trans,check the clearance,and machine the clutch pistons,if possible.Thanks in advance ladies and gents-Lew.
