| Well, I don't have much experience with a hot day up here in Alaska, but when I drive from faibanks to anchorage in the summer (about 70-80 degrees out), mine usually runs about 140-150 degree range. If I am in the city or pulling hills a lot, I will see 180-210. If your torque converter is locked up, it should settle at a decent temp until you get back in the city. As far as fluid, anything that is dextron III rated or higher is good. I am running Mobil 1 sythetic in mine with no problems. A lot of other guys use transynd (allision synthetic fluid). I would just make sure you change your spin-on filter between 5000-10000 miles. It is easy to do and cheap insurance on your tranny.
