First, and most importantly, congrats on the sticker!!! :drinks:
I thought you could flat tow with a 2-speed Atlas? I seem to remember reading that it wasn't recommended with the 4-speed, but you could do it with the 2-speed. There were some limitations though, unlike with the stock transfer case.
EDIT: Ah, found it!

"DO NOT FLAT TOW an Atlas 4 Speed without removing the drive shafts! The planetary unit AND additional bearings will NOT receive the oil needed as they would under normal driving conditions- damage will occur! We can only recommend flat towing an Atlas 2 Speed (after the 500 mile break-in period) for a maximum distance of 300 miles and then starting up the vehicle and with transmission in gear and Atlas 2 Speed in neutral letting it idle for 5-10 minutes. If you do not wish to stop and circulate the oil, we actually prefer that you remove the drive shafts from the vehicle."
Correct. 6L80 transmission is required for this swap. It's a much better, 6 speed transmission. You can't use a rubicon transfer case. Atlas or a sport/Sahara will work. I'm using a sport t-case. And from what I've been told, an Atlas can't be used if your flat tow your Jeep on the ground.
