Default raise in rpm's questionable

my durango keeps reving up a few hundred rpm's but only does it is seems above 30, i know this is where the trans. will try to shift but i think it also does it in higher gears as well, though i dont drive on the freeway hardly ever so its kind of hard for me to say. anyone fimilar with this problem? ive been told to put some trans additive in it by a mechanic, he said he hardly ever recommends additives to ppl but has had luck with it on specific things. what do yall think?

Check the filter... sometimes the trans filter will get a little clogged and make shifting a bit hard. Also, check the level of trans fluid.

i would check your K&N air filter as well, if you havent cleaned it in a while, that could be causing your engine to run alot harder than normal.

havent checked trans filter, but air filter was fairly dirty havent really cleaned it yet, but knocked it off and put in some fuel system cleaner and it seemed to help a little.
also this truck doesnt seem to have the HP on paper that i thought it would, im seeing all these new cars with like 4.6 v8 380HP i know they may have put some electric engines in the back to help with MPG but wow thats high

If it keeps on doing it, you might consider changing the throttle position sensor. My mom has a 2000 Dodge 5.9 that started doing the same thing a couple years ago, and it escalated to the point it wouldn't hold an idle. Changing the TPS solved the problem. I have seen other Dodge V8's in that year range have the same problem as well.
