When I shift gears in my 98 dodge Ram it has zero power especially up hill.The rpms go strait up and then drop back down on their own w/o me shifting then begin to go up again until it is time to shift up.I been putting it off but it is getting pretty bad .once I get up to speed Im ok in traffic unless I go up a steep hill then the rpms shoot up and I have no power. But it takes a good while to get up to speed.The turbos sound ok and I just changed the fuel filter but I think its the tranny or clutch anyway.Has anybody else expirienced or know about it.I aint much of a mechanic once it gets past the motor.Thanks J.J.
