My 88 aw4, 163k, has a annoying problem when i am in overdrive. Right when O/D kicks in i get a tugging from the rear of the jeep. Like when you have a fish on a fishing pole, but two or so... tugs every second. It may do it more, it may do it less, But from 0-44 it is fine. The engine is not missing when this is happening. It only does it in overdrive so i am ruling out the axle. I replaced the 75 dollar tps, to no avail. I know there is a way to adjust it, but i dont have a DMM to test it. If anyone knows what i am talking about, or experienced this, and fixed their problem, let me know. Thank You!
