Hi folks-

I recently bought a 93 dakota (extended cab, v6, 4x4, auto) to use as a
work truck. Needed new shocks in front and brakes, which I put in
without any trouble - it's a nice roomy car to work on. Otherwise it's
been pretty dependable engine-wise.

It's started developing an intermittent tranny problem, though. When I
got it on the highway after I bought it, I noticed that it tended to
shift down into third a lot when going up minor hills. Now it's started
to not want ot go into fourth at all. I'll get it every once in a while,
but mostly it's driving in third. Bad on gas mileage.

The previous owner said he had the tranny rebuilt a year or so ago. I
noticed that the transmission fluid level was very high, so I pumped out
a quart or so to get it into the right area on the dipstick. It's made
no difference. The button that should disable OD is missing from the
dash. The tranny shifts smoothly in every other gear and reverse.

So any thoughts on what might be causing this? I've read that the
throttle position sensor can cause problems going into 4th gear. Could
this be the trouble for a 93? Or maybe the speed sensor? Any procedure
on how to test them? First Dodge - still learning my way around it.

TIA
