On my 06 2500 4wd 5.9 the truck wants to kind of jump back and fourth between 1&2 gears when ya goin slow or just easing off from a stop. Truck has 55K on it started doing it bout 10k ago has anyone else had this happen or anyone know wat it is, im hoping dealership will fix it. I dont tow anything just a daily driver and all i have is exhuast, hypertech and an intake it started doing it while the truck was still completly stock also.
Any info I would appreciate it.

 

There is a TSB out to replace a solenoid. If you got less than 36k mi on it it will save you about $130.

 

Thanks do you know which solenoid it is?
