Hi Guys, We have a 2024 3.5 ton campervan with 9speed auto. when we go downhill van start to enginebrake with or without cruice activated. I use to shift over to manual mode to solv that in a way. i can only shift 1 to 5,th gear not gear 6,7,8,9 whch means low speed . normal or not ? or do i need to contact a fiat shop to make the upper gears to work?
