17 silverado TCM update?

[NYMetsFan86]

hello!

 

I have a 2017 silverado that i financed in early february. I have had read elsewhere that some owners were getting a shudder feeling and that it may be the torqe converter. Either way, is there some type of tcm update that has come out since february? Thank you

Nothing that I'm aware of. Are you getting a shudder?

I am not certain its a shudder, it has happened twice on a cold start at low rpms. Could be described as a shudder or a rubber band feelong for a second....Then it goes away in aeconds. Has really only happened twice, after 3000 mile mark. Drove from nj to FL hoping that does not have anything to do with it. I do have a custom ecm tune but diablo sport has not cracked the TCM yet, so that remained factory Either way. The tune is nothing crazy just an 87 custom tune. yesterday was the second time and it went away quickly. Hoping to hear that its no big deal. Thanks for the help and info
