My truck is acting a little weird whenever the temp approaches 90 degrees outside. The truck takes a little longer to shift to 2nd, and the noise of revving the engine seems higher in pitch, but only when in gear and starting up from a stop. Revving while in Park sounds normal. Literally, one degree ambient will make the difference. 84 and I'm fine, 85 and it will do it. One other thing, it also seems to act normal if I punch it, almost as if the 1500-2000 rpm range I hit when slowly accelerating causes it, but not the higher revs of a fast takeoff. I'm going to change the fluid most likely anyway, but I was just worried that there would be no warning if this thing was really overheating. One more thing of note, I DO have the transmission cooler option. I just added a billet grill and chrome bowtie, so I had the front off, and I inspected the lines, and the little radiator, and everything looks fine (no leaks. damaged fins, or anything).

No light to my knowledge and I ran my old tranny up extremely high a few times at the track. An aftermarket tranny temp gauge pays for itself in transmission repairs, IMO. They're inexpensive and easy to install. With outside temps that reach that high, you might want to consider an aftermarket cooler as well. These trannies are weak as hell.....even the built ones.
