New here. Just picked up a '76 Cj7, with the 304 V8, 3 speed. Runs great, drives ok. Haven't had time to investigate if it's still the dana20 tc, or 300. Shift selector pattern is for the 300, not the 20. Question is, it drives "best" in what is 4 low. It drives in 2 high and 4 high, but is very, lets say slow/hard. Haven't tried to push it, cause I'm afraid something is going to snap or jam in both 2 and 4 high. Any thoughts on where to start besides determining what TC it really has.
