Upgraded transmission cooler

So last summer was the first summer with my truck. It has the factory towing package. I was taking a trip through the mountains, lots of climbing, not a lot of weight in the truck, and NOT towing. It was warm, high 80's. I noticed my tranny fluid topped out at 205 on the steepest climb. This seemed very high for normal driving, even if its through the mountains.

Ive been thinking about getting a camper. My concern is if thats the temp without towing in the hills, what will it be with?

I did check fluid level, and everything shifts and feels fine. Does anyone else see these temps?

Has anyone ripped off the factory cooler and upgraded to a larger aftermarket?

 

Were you driving in D or in 4?

 

Everything was normal. Come to think of it, i may have shifted into 4 a few times on some climbs

 

205 isnt anything to be worried about.

 

i wouldn't be worried about that temp if i was towing, but i wasn't. I am worried what that temp will be with 3-4000 lbs in back of me

 

Have you tried 4th instead of D on a long climb? Higher engine rpm might help with temps.

 

good to know other vehicles had similar experiences. lets you know things are probably normal
