I need to remove the shifters to get at the transmission countershaft which has 2 gears with broken teeth. I read in this forum's archives that you should move the shifters out off their respective detents and pin the pawls with small nails. This will allow the shafter to be slid out.

My question, I have the shift assembly off and am looking at the shifters and shaft, what do I move to get the pawls to come out? Can I rotate the shifter shaft with vise grips after loosening the shaft set screw? Or do I have to move the shaft laterally to get the shifters out of the detents? I don't want to damge any of the mechanisms.

Rotating the shaft will pop up the detent pin or sliding it partway into gear. I just use old wire in the holes.

you have to remove the shafts completely. Pining with cotter keys will work better for you, pin before removing the shafts or you'll be kissing the springs and detent shafts goodbye. There is also a sequence, believe it it removing from rear forward and installing in the reverse process.

How do you get the pawls to extend to enable pinning? Do you move the shaft or the shifter to come out of the detent with the idea of causing the pawl to extend? How is this done?

Lightly tap them to one side or another with a brass/plastic mallet, then pin the detent.
