Chevy LML TCU issues

[Drupanddown]

Hey guys I rember another thread about Chevy TCM on back order a year or so ago. My 2013 Chevy LML is throwing a U0101 fault. Trucks in limp mode shift erratic and service stable track system on the dash. Checked all the chatGP suggested stuff batt voltages, fuses,brake fluid levels ect. Pulled the 80 pin connector on the TCM and check the harness on few test points off UTube all check out good. I think the TCM is bad any one have a source for a new module. Trying to tow the boat to river sat morning throwing a Hail Mary here.
Thanks for any insight

This place was able to get me a TCM last year when my mechanic couldn’t source one. Recommended by a member on here

same exact codes and lights i had, it was just past covid and no chips being made. dealer said out of stock with no eta. I accelerated the issue with GM and finally got one of the first ones made. waited 9 months for GM to make a new one for like $800 during this time the junkyards were asking for $2500 for a used one

it had to be programmed once installed
