This happened about two weeks ago and I haven't gotten around to it until now. My '72 had been sitting for a year or two before I bought it and earlier is anyone's guess. It has a 4-speed trans that got stuck in 2nd gear while I was doing some shakedown runs close to home. Whatever happened, it's really stuck, but fortunately I can still move the car. Anyone had this happen before? I did once with a '65 Mustang and it was caused by a detent screw falling out inside.
