Funny how my last 3 or 4 trucks have had transmission temp gauges and OE coolers and have run between 215 when towing in the summer and 100 in the middle of winter during 100 mile trips. How can it have a 115 degree swing AND have a thermostat. My current truck (new GM 8 speed) does seem to have some sort of thermostat because it has never gone over and hovers at 190 in summer even when towing. But when not towing during the winter it will run anywhere between 120-140 and stay there for a 100 mile trip?
