It would only be covered IF it was recalled for it. A TSB is only a company "cheat sheet" it means that a bunch of folks had a problem,here is what we found,Here is how to fix it. It is not admission of faulty design/components, just add ons to the manual saying how to repair something they may/may not be a problem.

You don't understand how things work. TSB's are designed to save time and money for the tech's in a dealership, by pooling the available knowledge from all GM dealerships. They usually deal with "pattern" failures.
By the way, the worst thing you can do is wander into a dealership with copies of TSB's you found on the internet, and demand that all the work be done. They will, (and should) simply laugh at you. You have to actually "have the problem" before it can be fixed. The dealerships answer to GM and cannot just be replacing parts willy/nillly....whenever some customer comes wandering in with a TSB.
Even if you were under the factory warranty, nobody is going to just "perform all the TSB's" that "might" relate to your truck. You have to have the complaint or failure present. Now if people were smart, what they would do is sit down and read the TSB and then formulate a complaint that might lead a tech/service advisor to then perform the TSB procedure. But of course you didn't hear me say that.
