I had a ‘81 Ford pickup with a 3-speed column shift that the throw-out fork broke and I was stuck in 2nd for six miles in heavy traffic. At stop lights I had to jam the brakes on hard to kill the engine and restart in 2nd gear! People sure looked at me funny with a bucking truck...............
Mine would fail to disengage 1st completely, but go ahead and engage 2nd, and lock the whole works up. You had to pull over, get under the hood and wiggle the shift linkages to get it freed up.
