confused trans????
 

I recently just purchased a 2007 dodge ram 1500 Qc 4x4 4.7 litre with 20 ich stock wheels....it seems that the transmission decides to up shift when trying to pass some one...and when driving the truck normally and not getting into the gas...it will upshift into 3rd or possibly 4th prematurely....resulting in the motor bogging down and "chugging" in stages back up to a proper rpm range for the speed....the truck has less than 1,000 miles on it and was in the shop at 300 miles....the techs said theres nothing wrong with the truck.....funny cause i think there is....i've drivin all the other trucks...(chevy..ford...toyota...etc) with comprable engines and they didnt do it!!!!!!....


IS THERE ANY ADVICE OR FELLOW DODGE OWNERS EXPIERIENCING THE SAME?????

PLEASE HELP!!!!
