Hello just bought a 1990 Dodge D350 truck at an auction with 30K miles on it, yes I am sure. While driving home it ran great except that it ran very high rpm at 60 mph and was slow to shift back down when I decelerated. While going up hills I lost speed with the gas pedal floored and the truck did not want to gear down or accelerate. Engine ran fine, did not overheat at all, just not smooth as I would expect. Took 3/4 tank of gas to travel 80 miles as the RPMs were so high just to travel 60 mph. Is this a transmission solenoid or controller issue? Been sitting for a couple years so I was hoping the highway drive home would blow the crap out of the thing and that it would run better afterwards but not the case. Ideas?
