Denny FYI, Just lost the TCM in my 2013 LML service truck. Had it rebuilt by circuit board medics. $1,200.00 with lifetime warranty and five day turnaround with overnight shipping. Just got it back. Everything is good as new. I hate to hear stories of people paying 3 to 4K for a used TCM or not finding one at all and trucks sitting for months at a time waiting for one.
