Transmission Class Action??

The problem is the low speed, like 25-30 MPH or even less.
Offroad, forest roads, and not highways.
At 75MPH should be plenty of airflow and RPM to keep temperatures controlled.

I've been under 25-30mph for hours on trails going up and down the mountains, all off-road or forest roads. These trips usually last 3-4 hours, average probably twice a week or so. I'd venture a guess that the average speed during those times is 15-25 mph.
