EVERY time I get held up going up these 10,000 foot passes it is because I am stuck behind some F-150 with the 5.4L huffing and puffing and doing like 20MPH. I think I will be fine then going 6 feet longer and about 1100lbs heavier. Power is not an issue on the new RAMS, I just don't want to be using up all my rated tow capacity - as you know these mountains here will tear up the unprepared and underpowered. In the summer I am sure you have seen the grade on I-70 near the Eisenhower tunnel looks like a battlefield with all the broken down steaming vehicles along the shoulder. If you can tow up here, you can tow anywhere. Thanks again, see ya on the roads

From what I've read, if you're just peaking for short periods at those temps it is not nearly as bad as if you were running for hours at those levels.

It's my understanding that the higher transmission temps affect the transmission fluid first, its useful life is diminished. I would change out that fluid as soon as practicable. I am wondering, for those of us who already have the factory tow package, is there is any further aftermarrket Transmission cooling we can set up?
