Just installed a shift kit in my 95 z28 it drove great for about three days then while passing someone on the freeway overdive was just like neutral and won't downshift into 1st. Any suggestions?

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.

My shifter is 2, D, OD. So no way to manually shift her.... I'm opening it up today after work I'll let you know what I see.

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.
