I just had my 700 rebuilt with a TCI rebuild kit and a corvette servo. I got it reinstalled with new stock torque converter. But it wont move in reverse. There is a very very slight drop in rpm when you shift it initially. It seams to shift fine into the forward gears. But im not sure as I cant get it out of the garage without reverse. Fluid levels are right on. I reset the TV cable according to how everyone says. Any ideas ??!??!?!??! PLEASE!!
