Bryan, Do you run an aux trans cooler? Trans temp gauge?
I replaced the stock AUX trans cooler with a larger Tru-Cool max 40,000 GVW cooler. This was necessary because the deer-guard and center lights blocked enough airflow the stock cooler was no longer adequate. Prior to those upgrades, the stock cooler was sufficient. I have a Banks trans temp gauge mounted on the A-piller.
Note: the highest trans temps are usually right after leaving the freeway, especially if I exit into a hilly area like most of the Portland area. Cruising on the freeway temps are never a problem. The only highway trans temps really got hot was coming west-bound out of death valley. I was right at 22k combined, and it was 107F out. I ended up pulling over because my rear diff temp gauge maxed out at 250F. Trans temp was getting high too and probably would have hit the yellow zone soon if I hadn't pull over to let the diff cool.
