Hey guys, just had my trans rebuilt and now my rear is going!

Anyone know of a good shop around here to get it rebuilt? Willie? Anyone? Please help. I just dumped 1100.00 into the trans and now this. I am trying to buy one from a friend of ChrisFormula, but in case it doesnt go thru, just want to get a back up plan in place. Even if I get it, might as well have my old one rebuilt with some good parts. Thomas
