It's possible the reverse pin fell out of place during assembly, it can happen pretty easily if your not specifically looking for that pin to STAY in place. If every shift is always made real clean and the linkage is adjusted perfectly the problem may not show up for months afterward.

When I bought the ERA the fellow mentioned that occasionally the linkage would lock up. Didn't happen to me for several months, then one day, backing out... I later found the pin in the bottom of the trans, no doubt it had been that way for years. Whew, I hope it's something else, the trans has to come apart to fix the pin.
