Check for low transmission fluid level.make fluid and filter not dirty has been changed.if all is good you could have faulty a 2 - 3 shift solenoid valve. or 2 - 3 shift solenoid valve harness or connectors faulty.

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!

There are broken wires in the wiring harness between the frame and your driver's side door. These wires control all the windows and door locks in a 95 Jeep. Same thing happened to me. You will have to cut the rubber boot to get it off and check which wires are broken and repair them.

I alsao own a 95 grand cherokee.
Certain windows would stop working when the drivers side door closed. I removed the rubber boot in between the door hinges that shields the wiring harness and found several wires in a condition of broken and/or shorting.
I will say these shorts also caused the battery to drain on several occasions when the car sat overnight.
It is easier to re-attach and work with these wires if you remove the harness plug from the door. There is an allen screw located in the middle of the plug...sorry I dont remember the size....
Hope this helps

You can take it to your Jeep dealer and have the service department try to flash the computer. This may fix it. If not you will need to purchase a shift control module. They are about $ 590.00. This is a very common problem on the Jeep Cherokees and Grand Cherokees. Hopefully you are under warranty still. If you ignore this problem this is what will eventually happen: You will be driving down the road and your vehicle will not want to go over 15 mph and it will shift erratically. Do not wait to correct this problem or you will regret it. Yes it is a very expensive part, but a computer in itself that the vehicle needs to function correctly.

P0301 is #1 cylinder misfire detected and is most likely related to a worn spark plug that is need of replacement. All plugs should be replaced if replacing one. Not sure how many miles you have on this vehicle, or if plugs were ever installed, but this is the basic step to take in diagnosis.
