Question about 1997 Jeep Grand Cherokee
Slipping is caused primarily by worn seals inside the unit causing the pressure to drop and not fully engage the clutch packs. Once that begins to happen the clutch material burns and begins to quickly deteriorate.
Pressure loss is also possible if the unit is low on fluid, or the filter is restricted...Most times filters become restricted with clutch material and as such that tells you that there is a problem, as the clutch material belongs on the clutches, not floating around in the oil.
There is no chemical that will repair broken or worn parts but the only one I've ever seen actually help at all is the sealer and conditioner made by Lucas. It won't fix it but it may buy you a little time. Your trans needs to be rebuilt.

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.

There is a vacuum leak under the hood. If it's a 6 cylinder, look on the drivers side for a vacuum line that runs vertical with a 90 degree angle fitting to the manifold. That one usually comes off. If it is a V8 look on the battery side for a broken or corroded vacuum line.

sounds like a possible shift solenoid. If it's due for a fluid change, do that and add a container of lucas trans conditioner. Likely you have a drain plug on the pan so if the fluid was recently serviced, just drain a quart out and replace with the additive, then top off.
If the condition does not change within a week, likely you will need better diagnosis from a reputable trans shop.

Depending on how many miles you have on it. You may need to have some repairs done. I don't know if there is much you can do to a jeep after it starts slipping other than try and change the fluid. The rebuild is the best option for you for sure. But you could put some no slip transmission fluid additives in it. Go to a parts store if you think thats your best option and tell them whats wrong and they will hook you up with some good additives. Go to Advance Auto or Auto Zone. The rebuild will be less expensive if the transmission still functions. Around $1000 versus the non functioning transmission that would cost about $1400-$2000. New transmission cost a lot more.
And don't forget! Please leave four thumbs up. I always try my best at explaining my answer to your problem.
