Some Jeeps will do that. When you feel the engine beginning to work too hard, lightly tap the brake pedal. That will disengage the overdrive. On long steep hills, shift into normal drive (3rd gear).
Also try flooring the gas on a straghtaway and see if the kick down is working. If not, try lengthening or adjusting the kickdown cable.
If what I just said has no effect, run a code scan. Could be that the MAP sensor isn't working properly, or some other sensor is out of range.
I have four Jeeps and all of them do that and run perfectly. Jeep is a bit conservative when it comes to the kickdown position. After a while what I mentioned becomes part of "normal procedure" when driving.

My 01 Pontiac Montana is trying to overheat at high power


If your vehicle doesn't actually overheat, just getting hot, I think that's the normal behaviour for these cars. My 03 AWD behaves the same way. When driving uphill, especialy when towing, the temperature rises close to the red marking, but I have never experienced it overheating. I think that the temperature has to rise much over the normal driving temperature to activate the two electric fans.

Will not go into 4th gear or uphill


Hi Msch, As your vehicle is a relatively late model I think it would be fitted with electronic transmission control modules. As you have lost power to the speedo and other circuits, you may have a problem with the speed and ABS sensors. The signals from those send command signals to the management system and control both vehicle speed and gear changes. Take the vehicle and have a diagnostic scan carried out. I believe the problem to be electronic and nothing to do with how much ATF is in the box. I do believe the electrical problems are related. Regards John

Roaring in front when going down highway


this vehicle has thermostatic fan when engine gets hot enough under load ie, going uphill it will engage and you will hear a roarining sound which during normal driving you probably wont notice, once the engine cools down the sound will go away.

hope this helps art

Why does my car loose power going uphill


YOU COULD HAVE CLOGGED FUEL FILTER AND FUEL INJECTORS.ALSO CHECK TRANSMISSION FLUID.IF LOW TRANSMISSION WILL SLIP GOING UP HILL.NOT ENOUGH FLUID TO BUILD UP PRESSURE FOR OVER DRIVE.

Poor performance on up hill drive


This could be caused by a low fuel pressure or poor plugs/wires. Do a fuel pressure test, if low replace filter, if still low replace pump. Also replace spark plugs and wires if you have not done so. If check engine light is on you can bring vehicle to local parts store to have them retrive trouble code. Thanks
