This picture is from my 2006 Jeep Grand Cherokee, Haynes Repair Manual. My Crossfire dealer service manual indicates that the Crossfire's automatic transmission is a NAG1. The 06 Grand Cherokee Laredo (3.7L V6) that I have, and the Crossfire both use the NAG1 automatic transmission (mercedes W5A580 transmission).

I would assume you can use the same dipstick level reading and fluid capacity since they are the same transmission. I hope this helps you with the temperature & fluid level. I converted the US units from the graph to Metric because my dipstick tool measures metric. Good luck. I hated working on a "sealed" transmission, and I still do. I serviced my Jeep tranny a few months ago and overfilled it. Its throwing a code so I need to go drain some fluid to get it down.
