Alright, so I just went through and replaced the clutches, seals, and some of the hardware inside of my 727, it's a 77 big block transmission in my 85 Ramcharger. Although, after looking at the valve body (stamped 67) this might be an older transmission since it was rebuilt in 99. Anyways, it worked before hand, but slipped heavily in first and after tear down, the rear clutches were shot, pretty much metal on metal. Anyways, get it all back together and now only reverse works, put it in Drive, 2 or 1 and no movement. I actually did get it to move about 3 inches once, but that's it. Reverse works all day though. I've swapped valve bodies, adjusted the bands, did an air check and both servos lock up, although the kick down servo seems to leak air quite a bit more than the reverse, so maybe that's the issue?
Anyways, any help would be appreciated. I'm tired and I've been searching online, but the only thing I could think of now is that maybe a wrong part was used since some parts were sourced from the 85 small block transmission that was original to the RC.
Thanks for any help/suggestions.
