727 help

[B.G. Smith]

I have a 89 Ramcharger with 727 trans. Got stuck in the sand at deer lease and grenaded the one way bearing in rear of the case. I changed out the case and put in new seals and clutches and now when it gets up to operating temp. , I prettty much don't have reverse, it works pretty good when first started cold and the forward gears are fine. I'm thinking the reverse band may be worn and running out of travel, is this possible? I checked the pressure on the reverse servo and had like 275#, pulled the pan and removed the reverse servo piston, everything looks ok, any ideas???? Thanks, bg
