Transmission Cooler
The new Tahoe and Suburbans do not have an aux. transmission cooler unless you order the 4.10 rear end. Also they feed the transmission fluid thru the radiator backwards (from bottom to top). This brings the oil in on the cool bottom of the radiator and exit on the hot top. I was pulling my 3124 over Monarch pass in CO with the outdoor temp at 55 degree and light rain. The transmission temp went to 240 degrees. I added a large cooler since then. I pulled a heavier trailer last week and my temp. never went over 200 degree.
