Haven't looked into it to far yet, but was wondering if anyone has seen this before. 74 duster slant six auto. Driving it up the hill by my house i manually shifted it to second to keep it from going to third as it always wants to but doesn't have the power to pull. Anyways topped the hill went to manually shift back to drive and it wouldn't shift. Got home, shifter stuck at second, can shift first and second. Popped the linkage off the transmission and the column shifts fine, but the lever on transmission won't go past second. What did I break?
