Hi Guys, I have a 99' f250 superduty 7.3 and when towing my travel trailer, the transmission temp is runs around 170-180 on the highway. My question is when I get to small towns or even the camp ground, the tranmission temp get around 225. I have heard about adding another tranmission cooler. Trans fluid is not burnt and pink and shifts fine. Ideas?? or don't worry.
