There were several transmissions put into your Grand Cherokee and of course the model depends on whether its a manual shift or automatic.
You can find the part number stamped on the transmission itself if its an automatic. Look on the drivers side above the fluid pan gasket. On the manual its on a tag near the drain plug. The numbers will have the part number, build date and serial number and you can cross reference this number by calling the dealer.
