Im having some issues with my truck revving high, I normally run my truck on cruise at 65 and my rpms are around 1700 to 1800, but for some reason now it is running at 2000 for no apparent reason and im not sure what is causing this, any help is greeatly appriciated.

TC unlocked? Does it do it all the time or cold or hot? Also, changed anything lately? Tires?
What gears do you have and tire size? How's the trans fluid?

the TC is locked and it does it weather its hot or cold, nothing has changed my tires are 35s and i have 373 gears, the trans fluid was changed about 9,000 miles ago and does smell a little burnt, the truck feels like it has an extra load on it on the high way, normal driving it runs fine

4wd? something in the driveline might be causing extra drag.

If the tc is locked, then rpm shouldn't change, just boost levels. I would think tc

My Samsung SGH-I997 made me send this.

the rpms dont change wile cruising on the high way its just running higher rpms than it normally does at 65

I'm saying the shouldn't have changed, unless the TC is slipping. But I'm not trans guy, just throwing out ideas.
