What's the best way to pull Hills?

With my 8sp trans in tow/haul mode, shouldn't the truck recognize the different grades and adjust accordingly?

If you set the cruise control, the 8spd will downshift automatically to try to maintain the set speed.

Where do you live? I'm guessing you've never towed in 100'+ weather!

I have towed in those temps. Why do you ask?

150' transmission temps while towing when it's over 100' seems hard to believe.
Especially because when I'm not towing and its 70' out the transmission will be in the 120 range. In the summertime my mom towing temps will increase accordingly to the outside temp. So you have almost zero temp increase when towing.
Also people say their 8speed temps when not towing are 180+
I'm not disputing that 245 is hot for the tranny. I just find it hard to believe you're at 150 when towing in the mountains and it's 100+ outside.

I had the 6 speed and normal operating summer time 90 degree temps were 130ish. If I sat idle in a lot yes they would climb but if the trans cooler had good air flow it would remain low. The 6 speed was much cooler running than the 8 speed.
