second gear
chevy 2 :
I had the same problem. The trucks runs great but doesn't shift !
You have a good top end speed right ?
I bet the screw above the 2nd gear adjustmentscrew came loose. Try to find it , I bet it's on the bottom of the tranny !
Screw it back in using some treadlock.
This schould do it , I had the same problem.
