Unscrew the shift knob and pull up the shift boot. Hopefully the shift linkage just came loose at this particular point. If it didn't come loose from here, you'll need the car on a lift or stands to get at the other access point. If it isn't the linkage at the shifter, do NOT roll the car forward or backward. Call Terry. There's a shift linkage piece that can shear off and fall into the tranny and will KILL your trans very quickly if moved.
Hopefully, it's a simple fix for you and not the sheared bolt head... Good luck!
