Listers including Bob and Dave,
Played with the switch on the gear shift knob today. I took it off and
inspected the switch and connections. Didn't see any obvious problems.
Re-assembled switch and went for ride. Shifted into O/D and tried to switch
out. Still didn't not dis-engage O/D. Hmmm what to do. I gently twisted
the the top of the knob just playing around. The O/D disengaged. Weird, ok,
tried O/D again and switch out. No luck, twisted knob ever so slightly,
bingo, disengaged. So, I'm going to try and crimp the contacts better and
put di-electric on them. Any other thoughts?
