Rebuilt 700r4 - no reverse
Hi. I just rebuilt a 91 700R4 with the TCI kit, and installed a B&M RV heavy duty shift kit. I carefully followed B&M's instructions for check ball placement.
I installed the transmission today and don't have reverse. I do have forward gears but they seem very weak. I can step on it with my truck in low range and still hold it, with the brakes, and my brakes are BAD.
There doesn't seem to be any engagement in reverse at all
This is my first automatic, and first time rebuilding one, and I don't even know where to start. Any ideas before I go searching for a new transmission?
