Howdy all, so I need some advice with my AW4. The issue at hand is when it's hot out, over 85*, and I've been driving over 55mph/2k rpm range for a while the tranny feels like it's slipping and there is a lose of power. There will be a lag and then the RPM's jump up. It does not happen all the time, just when I've been driving it for a while, 20 mins plus, in the heat. When going up a hill the problem seems to be more persistent. All other gears are fine it's only OD that seems to have the issue. Currently, it has a tranny cooler that bypasses the cooler connected to the radiator. It had the same issue before when ran through the radiator. I've been doing some research and a few people have mentioned that the TPS may be the culprit. A few months ago I had an issue where the jeep would not turn over. Would crank but not turn over. It sat for a few days went to go back and it fired right up and drove fine. Had also read that the TPS may be faulty. Any advice is appreciated.
