On a warm day driving up Highway 18 to Lake Arrowhead the trans temp will read 220 degress. That is without any trailer and no real load other than 3 passengers, two of which are 6 years old or younger. I've tried it with the A/C on and off and it makes no difference in trans temp. The factory transmission cooler on our Yukon is pretty small and before I tow anything I'll be swapping the factory unit out for a larger and hopefully more effective cooler.

My Tahoe gets up to 230 on the 18 going up the hill. Also no trailer; just 4 people and a dog.
238 if it is a hot day.
