Il start back a few weeks ago from the 1st time I had this issue, so a few weeks ago I was towing the same trailer with the same quads out back 4 sportsman 850's and going up 7% grade up the mountains in colorado my temps shot up to 245 so I pulled over and cooled down then made it over the pass, back then I had a full race intercooler and I thought that was just blocking my trans cooler but since I was having boost issues with the full race I sold it and picked up an afe intercooler, well this weekend I went back up the mountains with same quads and the Temps started climbing to around 235ish even 240, I don't no what the deal is, it used to pull heavier loads (9000+) up smaller grades with temps around 205ish. Anybody now what could be up? I also thought that mabe the fluid Is burned up so mabe that's one of the reasons it's not cooling anymore? Anyways I dropped my truck off at Ford this morning to do a transmission flush and see what happens. I also thought of buying an afe deeper trans pan would that help too or is it just a waste?
