Is this a Grand Cherokee with the 4.7L V8?
Ok, first of all the AW4 transmission is absolutely bullet proof as long as it has had regular fluid changes and was not abused. I had an AW4 in my Cherokee and racked up 247,500 miles on it before I sold it. No problems at all with that trans. Now the 4.7L V8 is a very good engine, and is probably good for at least 160,000 miles before needing any major repairs as long as it was never overheated, and had regular maintenance performed.
Hope this helps, and let me know if you need more assistance with this,
The AW4 transmission is the "transmission" only. The different transfer cases available determine which 4 WD system you have. If you can send me the Jeep's VIN# XXXXX mileage I will look it up for you,
Ok, here is your vehicle information. You do not have the AW4 in this vehicle. It is the 45RFE trans which isw also a good trans (not as hardy as the AW4 however) afgain though if it was maintained well, then you should expect at least 160,00 miles out of it.
The transfer case in this vehicle is the Quadra Trac II on demandXXXXXsystem. This is a reliable system.
