Ok, back story... so as you can see from the pictures, i decided to relocate my intermediate roller clutch/sprag into the pan, and that race wasnt happy being 1 piece. that was a TCI hardened race. the 1-2 accumulator spring broke and hammered the piss out of the accumulator piston, as well as the bore.
trans was a 76 case out of a 2wd something, i built it myself about 8 years ago(my first trans ever) i used a full tci rebuild kit, with trans scat shift kit, hardened outer race, trans worked fine until it didnt. it also had the direct clutch piston machined down to fit more frictions/steels
it has been driven hard along the way, twisted off the imput shaft, ripped the bolts out of the b&m converter and broke flexplate, destroyed another b&m converter. fixed witha hughes 2500 stall converter to match new cam that was swapped in, ATI input shaft and scat SFI flexplate, ran for about 5 years like that before the sprag let go. it sits behind a dart headed 10.5:1 383 with a full roller valvetrain with an erson 284/296(IIRC) cam with .548 lift, and a quick fuel tech. 750 double pumper.
ok, now for the problem at hand
the 1-2 accumulator bore is not looking so hot, i know there are sleeve kits available, but would like to avoid that. i kept the original th350 out of the truck from 1974, 29k miles on it, can still read borg warner on the frictions, case looks immaculate.
i would like to use this case. everything looks the same, except this ones front pump only has 5 stator rings, the pump in my current unit has 6. i already went and bought a replacement pump as the old one was damaged from the sprag failure. it is a 6 stator with teflon rings. can i use the case with all my hard parts and 6 stator pump? i was thinking so, but couldnt find any solid info.
next thing is, my valve body i had in my failed trans has a different number stamped on it vs the one i got out of my core trans, the core one is out of a 1/2 ton and failed trans is a 3/4 ton
also i have been reading about people double bushing' the sunshell(dont know the name of it) part with the gear on top and bottom, then drilling out the hole in new bushing, is this common practice?
sorry for the long post, thanks for any and all info
