727 (340) TRANSMISSION REBUILD QUESTIONS THREAD

Rear clutch is engaged in forward gears only. So it can only drag at low speed in reverse. I shoot for .025". The front clutch likes .012"-.015" clearance per friction. I'd swap in a 4 clutch front drum. If it's the early small pin KD servo use the inner and outer springs. Raybestos or Borg Warner frictions will be fine. As many springs in the front clutch as it has provisions for 10-15. A TF2 shift kit is a nice addition. 3.8KD lever prefered. A deep 46rh pan from Ebay. With a quality front band this setup will easy handle 700hp for years.
