I won't tow in OD anymore.

With a shift kit, cooler and servos, from Denver to Northern Wyoming I tried to tow in OD some of the way, but it created too much heat. The TCC kept locking and unlocking which makes a lot of heat, not to mention 4th doesn't hold that well with a trailer yanking on it so that too was making a ton of heat.

I've got 35" tires, 4.56 gears. Was turning about on average 2500 RPM going 65ish on the way home in 3rd. Got better mileage in 3rd too.
