Think I see why you are having overheating problems. I just read your other thread, I see that you are pulling 3.55 gears. That is a pretty tall gear to run behind a converter like that, and the tires look pretty tall too, probably 28"? I think you are running too much overall gearing for a converter like that, I would try a shorter gear. I still think there is probably another problem there too, but the 3.55s are almost certainly a contibuting factor.
