This happened to me as well but I just pulled the fuse out that is in the black box under the hood marked ATC, left it out for a bit then put it back in. I know....sounds silly but its worked ever since...2 years about. So give it a whirl before just spending $400 dollars. Maybe I was just lucky.

that worked for me too for about a day then it went out again this time for good best thing to do if that doesnt help try and find a tccm from a friend same year model etc and swap it i did that and it worked withmy gfs fathers, in fact his friend hooked me up with one for free from a wrecked LTZ at his job just plugged it in and was good to go 2 weeks so far no problems yet didnt have to get it reprogrammed or anything

Hey trailblazin08 -

From where did you order your new TCCM? I'm in the market unfortunately - saw one on eBay for about $200 - did you order yours from there?

Thanks!
