hi all im runen a 98 4.5 auto, on steep hills when it comes under load in low range and with the auto in low it wont rev over 2000rpm right boot hard into the floor even if traction is broken it just sits there spinning at 2000rpm . iv had this problem since i got the truck 18months ago ,the 4.5 give up the ghost 2 months ago so i fitted a 5ltr ss comodore v8 now it goes like a dog shot in the arse on the road but still wont pull over 2000rpm on steep hills dose anyone no if theres sum sensor on the auto or tcu that wont let it rev or has the auto had the dick ??? my mate has a 96 v6 auto pathfinder and when it looses traction on a hill you dont wanna be standen behind it with rocks and **** flying , it will rev to red line no problems this is wot i expected from the patrol even more so with the v8 fitted . iv asked all the mechanics and auto blokes around my area and they look at me as if im the idiot . (well maybe i am ) anyone having or had this problem or no the solution ??????
