I towed our racecar trailer (10,000 lbs.) home from Bakersfield yesterday with my '07 for the 1st time...Went 65 MPH up the Grapevine, 2600-2700 RPMS in 4th gear...Air temp was 60*, trans temp was 150* at the bottom of the hill, 170* at the top of Tejon Pass, and 150* again after going downhill for awhile...

I'd say only a 20* increase was pretty good considering the length of that grade and that I was running a decent sized tune...

Should have more results in May while heading to Vegas...

X2 on Mike's cooler. Definitely worth the investment.

My truck was in a collisionn (popped my tranny cooler) and I made sure they put another Mike L cooler on as I saw the before and after results of his cooler. My truck would not have gone back together without one.

Thanks Mike!
