  That's a good question. Over-the-Air technology allows some software updates for certain vehicle components to be downloaded and installed over a wireless connection. Updates are downloaded and installed via Connected Access or by connecting your vehicle to a Wi-Fi network. When an update is made available for your vehicle, you’ll get an in-vehicle notice. This will happen the next time you turn your vehicle on or put it in park. We recommend connecting with your preferred Chevrolet dealership about any suspected missing vehicle software updates for your 2021 Silverado. Their staff will be in the position to assist. To learn more, you may visit www.chevrolet.com/support/onstar/data-wifi-hotspot/software-updates If you have any further questions, please let us know at: https://s.chevy.com/support-request and fill out the support request form with all pertinent details. This form helps our team gather the right information and ensures your request is routed appropriately.

  Didn't I read where if Gm does the valve body on the "Allison", you get a 10yr/150k warranty? Kinda wish mine has a minor blip around 24k. Get a free trans service, and a pile of warranty.

  Put new plates on Pepper. I guess the state thinks ten years is long enough.
