Right. I almost never push the little button on the side.
Only time I use the tow/haul/pull mode is during a race. And it's hard with my front axle, extended body weight, and 32" tires. But when I do, I'll drop it to 1st, push the Overdrive button (OFF light illuminates), and place my left foot over the brake and keep my right foot on the gas for a quicker response. If you know your redline RPMs, you can manually shift out of 1st to 2nd (w/the column shifter). By 2nd gear, there's no need for Drive cause they're way behind me anyway. Yea, right.
On the highway at 50 or 60 mph, if you want a lower gear to get more pickup to accelerate, all you have to do is step on the gas pedal. Welcome to the world of automatic transmissions. I'm sure you know this. I'm not trying to be an ars.
As far as who's overheating... neither one should as long as you treat your vehicle nicely (unlike me) and make sure the T-fluid is always the right color. But, yes, if one or the other is going to heat up faster, it's the auto, because of the characteristics born from the factory (sadly). Something us performance hungry fiend's always need to remedy. A transmission cooler (maybe a Superchip) and a relaxed foot should fix your concerns.
