Check your speed sensor pickup on the T-case. I've seen a few posts on this type of issue lately. Also, check the twisted wire coming from the t-case to your DRAC module. Be sure there aren't any frayed wires. I'd probably try replacing the t-case sensor just for the heck of it. You might just find another one at the junkyard or a new one.....
