That is why I took mine back to the dealer. What I say is true, They had to hook it up, to the computer. The tranny tech says they ussually do that, when the truck gets to the dealer, but some slip by.

Also my son drove my truck (I had a weak moment) The next day, It was hangin in the gears a bit longer then normal, but calmed down. Well I also got pulled over by the cops, to tell me I was doing big smokey burnouts at the High school. I told him I was not, my truck was described because of my mud flaps. (very distinctive) The the cops showed me the rubber metled in my wheels wells. (We laughed whe I told him my son had the truck) Then I remeebred what the dealer said, and after a little while, shifting went baqck to normal.

Things change to as mileage climbs. I am not a computer tech , but it sure was weird geting used to this tranny, and the way it picks and chooses gears.

I agree with post 12
