ok... it slows down seriously when going uphill, doesn't accelerate as quickly as it should (i'm assuming it should have more pick up than my 4 barrel stratus) and just seems wimpy overall. don't know much about the mechanics of it, just trying to gather info for my ford experienced counterpart to work on my mopar...
no, it doesn't kick down. traveling on the highway, or a hill in town for that matter, it just slows down. on a recent trip i was cruising at about 65 on a hilly road and it slowed to about 40. it doesn't seem to have the balls to pass a car on the straight flat stretches either.
Sounds like you should check and make sure the kickdown is working properly. With the throttle wide open make sure there is no slack in the kick down cable. How many miles are on this truck? Sounds like there may be more than just a plugged exhaust-unless you have or still have the catalytic coverter on it. If those are plugged up then that would cause some of the problems you are explaining. Could just need a good tune up as well.
