6 speed locked in 1st
Need some help, My tranny has a fresh rebuild, the only time that is on it is at the track, with about 4 passes. I have been backing it out of the garage weekly to work on the car, Yesterday was no different, reversed out of the garage, put it in 1st and shut her off. Went to back it up a little more and it is jammed in 1st gear and will not budge. I tried revving the motor, revving and trying to pull it out of 1st the same time and no luck, What the hell happened?
Wish I still had the pics

Pro 5.0 shifter..
Maybe:
Bent 1/2 shift fork
Mangled 1st gear syncro keys
Mangled 1st gear blocker ring
I would pull the shifter and rule it out. Then try to manipulate the shifter rod where the shifter connects, move it front and back. If its still jammed, your fukd and the T56 is coming apart.

Sounds like a Key popped out of the slot on the 1-2 Slider and it's got it in a bind.
It will have to come apart..
