This is my PERSONAL overdrive experience from 1978. My 77 Volare Road Runner I bought new off the lot with a 318 2 bbl and overdrive tranny. After about 3000 miles the tranny would lock up in gear between shifts. I had to pull over to the side of the road and whack the shifter around to get it out of gear. It happened multiple times. Eventually I swapped it out for a proper 4 speed. I'm sure after all of these years someone can chime in and tell me what was wrong but that was my experience with a factory new OD gearbox.

Most of the times when this happened, it was because one of the fingers of the lever on in interlocking lever on th side cover would snap off. It was a pisser because they would still shift most of the time, but every once in a while, the lever would get out of line and not shift. The best fix was to either beef up the levers in the side cover (done many of them) or just change out to a ball and detent cover.
