Ijust purchased this truck and at about 60 mph it wants to shift in and out of overdrive constantly with very little torque on the engine. Any ideas? It seems there might be an easy solution with a new sensor or ?

Can you feel it actually shifting, or are you noticing about a 200 rpm jump up and down ?
Most likely, what you're feeling isn't a 4-3, 3-4 shift, but the torque converter locking and unlocking. Two common causes of this are a bad throttle position sensor (TPS), located on the throttle body (on top of the intake manifold), or a bad brake switch, located on a bracket alongside the brake pedal arm. Both are easily checked with a voltmeter (an analog meter is better for testing the TPS), and both are inexpensive (and simple) to replace.
There are other possibilities, but these are the most common.
mine was doing the same thing last week. it should be out of the shop tomarrow. transmission rebuild
But your transmission / engine combination is a known klunker...
yes they are! but when they are right :) actually I think the dodge automatic is the weak link in all their 90's on trucks, but due to a handicap it is easier for me to have the automatic.
It shifts
Thanks..I will check.
