I'm going to guess since you didn't mention which fluid...Transmission?
First find out which unit you have (usually an id tag on it somewhere ) Then look up what kind and how much fluid in your owners manual (usually around four quarts...unit holds more but you can't remove it from the pan) Remove all pan bolts and lower pan. (some units have a drain plug, use it first if you have one ) you will see the filter attached to the valve body. remove it and install the new one, Make sure all gasket material is removed from pan and trans. Clean any metal etc from pan and internal magnet (there is always some in there but should not be a ton of it) Then put pan and gasket back. Make sure you can turn each fastener easily to make sure they are not cross threaded and only tighten them after they are all in there. Bolts do not have to be tightened down like they never should be removed again (snug then a little bit more)tighten in an X pattern not a circle.Replace about half of the fluid with car off, then put in remainder while running. Put your foot on the brake and shift to reverse then drive a few times then check fluid level.Low is bad, a tiny bit (less than half inch) over is OK.
Drive for a short ride, check again for leaks and re-tighten if any are found.
If trans was exceptionally dirty and yours has a drain plug, I recommend that you use a generic oil on the first change, then in a week, drain oil again and re-fill with good brand name stuff. and perhaps a bottle of lucas conditioner.
Good luck!

The dealership has at their disposal far more and better testing equipment than most normal repair shops...their technicians are supposed to be well trained and competent...Yet, in one week you note that they did about a half days actual work and in doing what they did, have not repaired your problem? Who is working on the vehicle...the janitor or a lube tech? And, I'll bet that they are going to charge you for not fixing it!!! You would likely do better getting yourself a decent manual and a digital volt/ohm meter, and going through the system item by item till you find it yourself. Or see if you can find a decent independent shop that specializes in Jeeps in your area...You may do better there. There isn't enough info for me to offer anything meaningful, but often the problem is common to a bad crank sensor, ignition switch or auto shutdown relay...but without real testing, I could be way off with this. Also...don't forget there is an engine underneath the electronics that needs to be checked as well.

Sounds like it is in 4 wheel drive mode.
If you have a switch to disconnect the 4 wheel drive it may not be working.
If the vehicle is full time 4 wheel drive or computer controlled 4 wheel drive you have most likely a locked in full 4 wheel drive mode situation.
Not good on dry pavement.
