Question about 2004 Jeep Grand Cherokee
While driving, Jeep transmission will slip into neutral, put shifter in neutral and turn ignition key and will go back into gear
The item that is electrically controlled and it turn controls the gear shifts is the TCM. transmission control module. They are prone to playing up and one of the reasons for that is moisture in the cable connections near the box. Have some one pull all the harness connections concerning the box apart and blowing them clean with air and ensure that they are dry and clean

First of all make sure you are checking the fluid right. Some people do not know that in order to check transmission fluid the engine needs to be running and the temperature needs to be sort of warm althought you should be able to get a good Idea just by the engine running. In this instance you might have a governer valve that isn't properly working to shift the engine when hydraulic pressure reaches a certain PSI. I would suggest having it flushed and put in new fluid and filter. If this doesn't work the problem is more serious and might need some professional assistance.

I had the same problem with my 94 jeep and i ended up finding out what was causing the problem was the starter relay in the fuse box under hood, i believe its the second or third relay. Try turning the key to the start position and leave it there and poop open ur hood and manuelly start the relay

As I said, trans fluid keeps the internal components "alive"... Low fluid level can cause burning of internal clutches, premature hardening of seals (essential to proper transmission of fluid pressure) as well as lubrication of necessary gear components such as planetary gear set (which can cause whine etc. which you now have) All of these components rely upon a constant flow of fluid for both cooling and lubrication. Depending upon how low and how long these parts had interrupted fluid flow, directly influences how much damage was done. I take no joy in telling you that you may have damaged your unit, I'd be far happier if I could give you a quick, inexpensive fix. But based upon what you have said, If I was working hands-on with this problem, I would make the recommendation I've already made. There are pressure tests etc that can be done at a transmission shop to verify to some degree of certainty what is going on within your unit. Hopefully they may find something other than what I've said. At this point though, it is wise to have it checked out by a professional, before you become stranded at a time when you can least afford to be.

SOURCE: 1991 Jeep Wrangler Stuck In Gear
I had the same problem, but in first gear. What I did to free it up, with the shifter out of the transmission, looking down into the hole you will see two linkages side by side with a slot in each. The trouble is the linkage got out of sink. What you do is put a large screw driver into (shifter lever) slot and try to move them (they are hard to move) to you find neutral.

Check for wear in the gear lever selector/gate mechanism.
It may have allowed the lever to select reverse, the 'jump' the lockout gate back to neutral position for selection of forward gears.
You may be able to de-select reverse if you access the lever directly at the gearbox case.
