There were three available yesterday, now it is down to two. There are other sellers but this one has the lowest price. I think it took about two weeks to receive. Very well packaged. https://www.ebay.com/itm/314091027125

Same problem with my 2017 Silverado LT with 8" screen. Random beeps, radio stations would randomly scroll, screen would lock up and not function etc. I disconnected the digitizer ribbon cable and the random beeping problem went away. Radio functionality is available thru the knobs but a bit cumbersome to use. (thanks to Wyatt1963 for the idea) I found a digitizer on ebay for $68. The price has since dropped. Replacement was relatively simple. Removing the old digitizer was a bit time consuming; I used a razor blade to separate it from the frame. I have about 20 hours on so on the new digitizer with not one problem. I just checked ebay. $48. https://www.ebay.com/itm/314091027125 (quick note: the sticky foam was on the wrong side. I had to carefully remove it then install on the correct side. the seller is aware of the issue) Here are a few pictures showing the original digitizer part numbers, the black lcd screen with digitizer and frame separated from each other and the whole assembly when first removed.

I had the transmission serviced today; new filter and six quarts. The technician let me in the shop while the pan was down. The old filter inlet looked clean. The magnet had a collection of normal clutch wear material. All is well. I guess I'm getting a bit sensitive in my older years. He said to come back in a few years and get the fluid changed.

I brought the truck in for oil change and transmission diagnostic. The short answer from the dealer is working as designed. The tech, 30 years experience with transmissions, drove the truck before the oil change then he requested we both go for a test drive afterwards. I pointed out when AFM kicked in/out and the rpm's moved; I could see the smile on his face. Yes that is normal. He went on to explain the balancing act between engine/transmission for optimum fuel combustion. These transmissions are constantly adjusting. I have faith that there was no BS here. No codes were present. His parting words, again no BS, was that my truck drove better than 90% of the trucks he sees in the shop. I will add here that they waived the $199 tranny diagnostic fee. I have 43,000 miles on the TC replacement. With two months left on the warranty, I will bring the truck in for a transmission pan drop fluid/filter change. If there is excessive metal then we will discuss what action to take.

I found this on Sonnax. Is this what you referring to? https://www.sonnax.com/tech_resources/845-6l80-6l90-transmission-tech-advisory-consider-an-updated-converter-in-your-next-rebuild

newdude, I like the idea of a data recorder. Thanks! I have an oil change coming up so will double up on that visit.

Thanks guys. I purchased the truck on July 2, 2017. With less than 52,000 miles and less than five years have gone by the drivetrain is still under warranty. How do I get what so far has been a reluctant dealer to take action?

2017 Silverado LT 5.3 4X4 6speed transmission 51,000 miles When I first bought the truck the transmission suffered from severe bucking or shudder under light load. GM calls it chuggle. The cause was "intermittent tcc delamination causing scoring on fluid pump". They replaced the torque converter, cover housing and pump cover along with a flush. This was at 10,000 miles. That seemed to solve the chugging problem. For the last year or so I have noticed that the torque converter unlocks and locks frequently at freeway speeds. When it locks, following an unlock, there is a noticeable lurching forward. This is not neck snapping but is definitely noticeable. This lurching motion also occurs when upshifting 4/5 or 5/6. While driving at freeway speeds (65 70mph) when I slightly let off the accelerator the rpm's rise about 200 then settle down. If I should slightly press down the same thing happens. However, when driving at a steady freeway speed, and holding steady on the throttle, on level ground I can feel this unlock/lock along with seeing the engine speed move up then settle down. If I engage cruise control on level ground it is worse and occurs more often. But, with cruise control on and there is a slight road incline there is no unlock or downshift. When I press hard on the throttle then it downshifts and accelerates fine. Locking/unlocking and lurching; I do not recall the transmission behaving like this in the early years. The dealer says if it doesn't throw a code then it is operating normally. I can see that there are times when it should unlock such as when under load, but should it be this happening this frequently and be so noticeable? Or maybe I am being too sensitive? Anybody experience the same thing? Is this normal transmission behavior?

I too had been looking and recently found this Gogear storage CNSLPLUS-BLA which fit perfectly on my 2017 LT. http://www.gogearmobile.com/organizers.html
