    I have a 98 mack ch with 427 and a 13 speed Im having trouble with the transmission not wanting to change smoothly from high range back down to low it either grinds and goes in hard or you have to come to a complete stop makes it hard when you are in a binding pull with a load of gravel or pulling a back hoe

    Are you dubbing clutching, if equiped is the cluching fluid up and when was the last time the clutch was replaced. Could be the throw bearing wore out also.
