727 Rebuild Advice

Standard bands are fine. Just get good ones, not cheap imported crap. And make sure and get a rigid front band. I've never heard of Alto Green clutches, just the Red Eagles and Borg Blue plates. Either them of Borg Blue plates are fine. As for what snap ring to change that's impossible for me to say because every trans. is different. When you get the clutch carriers rebuilt and check the clutch plate clearance you determine which selective snap ring to use to get the desired clearance. When I used to rebuild them a lot I kept several different thicknesses on hand. In your case what I'd do is take each clutch pack apart and wipe the trans. fluid off the clutch plates and steels and measure the the clutch plates and write it down then re-install them in the clutch carrier and check the clearance. Lets say the front clutch discs' ave. thickness is .087" which is .008 less than new discs and there's 4 discs, that means .032" is worn away. You then measure .100" clearance when assembled and subtract .032 (the amount worn away) and you come up with .068" clearance your great with that snap ring but if the clearance measures .130 you'll need a selective snap ring approx. .030~.035" thicker than the stock one that's in it. Same goes for the rear clutch pack except the clutch plates in them are .068 thick in stock form. You use the same formula above to determine what thickness snap ring you need.

As for the comment about replacing the wavey snap ring, you can find them in either the rear drum (most common) or both the front and rear drums. I leave them in the rear drum because it's not a shifting clutch so it doesn't hurt anything there and replacing it will only make the trans. engage in gear harder. Now if you have a loose converter it will absorb a lot of the shock of when you drop it in gear so you can replace the wavey ring in the rear drum if you need to too obtain the desired clearance. If you find one in the front drum replace it with a flat ring. Also on the shift kit I see no reason to not install one first. The Trans-go kit is a fantastic kit that not only improves the shift but makes the trans. last longer.
