Strictly my opinion, but the temps do not seem to high to me pulling 6,500# in Colorado foothills. The transmission will get much hotter when going downhill using the jake, and the transmission is designed to run much hotter, especially with synthetics. All I would do is steam clean the radiator, not high pressure spray.
