can you manually downshift to 1st gear?

sounds like it might be in limp mode. need to check all of the wiring for the tranny. i had that happen to me and had a bad shift solenoid. changed them both and it fixed the problem.

I replaced the servO with a corvette servo. And otherwise it was just a standard shift kit. Draped out most of the springs and the pistons and pins.

Well excuse me.



I think it might be the shift solenoids. We took off the pan and everything was in place and I wiggled the 1-2 shift solenoid and 1st gear came back for a little while but after about 5 min it was gone again.
