Cooling the fluid is only half of the heat ex changer's job.
It also warms the fluid in cooler climates.
You really should install a tranny temp gauge if you're towing.

When the TC is locked very little heat is generated.
If you install a cheap and easy lockup switch and use it wisely you can keep your temps way down.
