no drive in forward and reverse after first start up.sometime i can feel it trying to move but not.and does not rev at first as well.
found brake valve block leaking replaced still the same.
but if you push down on the rev pedal very slowly it will move but it wont do it in forward.
when it move in rev then the truck will drive around ok.when truck is turn off then go back to it wont drive unless you press down on the rev pedal very slowly.
