Transmission cooler

I'm taking a trip from Minnesota to Seattle area this summer pulling my fifth wheel. I have a 2011 F350 6.7 diesel. I have a 2005 Jayco Designer 38' fifth wheel. With it loaded with everything it should be about 13000 lbs. Just wondering about the mountain driving. Will I need a bigger transmission cooler or will I be fine?

TorqueShift tranny will be fine with the factory coolers. More important is if you've kept up the fluid and filter change schedule.

I haven't done anything with it yet. But I only have 58000 miles on it.

The 03 thru 07 TS trannys were 30,000 mile flushes and external filter change. The 6.7 TS trannys I think are 60,000 with an internal filter but I'd have to get my book out to verify it. Check your owners manual. If it's 60,000 I'd have that done and not worry about it.

Your flush is due @ 150,000 mi.
