Not impressed.... Ok I had a 07 Dodge dually 6.7 auto that was 2wd and now went to a 2010 Dodge dually 6.7 auto that is 4wd. Trucks are the same except for the years and one being 2wd and the other 4wd. Anyways we went of a couple hundred mile trip with it towing the same Montana trailer. The old truck once it got into 6 gear would purr right along never shift unless there was a steep or very long grade. Which means here in Texas that was rare. The new truck would not stay in 6 and would drop to 5 on any little incline. Also didn't seem to have the spunk on one of our steeper hills. It runs up thru the gears real well with no problems. The tranny and engine temps stayed normal. But I am gonna run it by the dealer but doubt they will do anything since there are no check engine lights or anything obvious. Sad the truck that looks like a beast is wimpy wimpy wimpy......
