Driving my '90 SHO today, I downshifted into second, and heard a snap, only to realize that engaging first or fifth, the shifter would move to third, and engaging second or reverse, it would go into fourth. Does anyone know what piece might have snapped, or how I would go about fixing this? I can go from 1-3-5 without neutral, and 2-4-R without neutral as well. I can start in third, and shift to fourth, but that's it. Any advice would be very much aprreciated
