Talked to my guy @ the dealership today and he didn't see too much of an issue besides the fact the the reluctor wheel is in the transfer case on a 4wd model and inside the tranny for a 2wd model.

Aside from that he couldn't give me much info.

Don't suppose anyone is looking to trade a lightly used 6L80E 4wd tranny for a 2wd version + cash...?
