I have an issue with flickering exterior and interior lights. I had the vehicle in to the dealer last winter with the same issue. They kept it for 2 days and let one of their service techs drive it home overnight and said they couldn't find any problems or duplicate the problem. The problem has resurfaced this winter and is worse than last winter. It seems to be worse when the outside temperature is below 40 F. I have recently had the engine light to flicker on 2 separate occasions while this is occuring and can actually feel through the steering wheel like you shut the vehicle off for a fraction of a second. It was like I turned the ingition off and back on very quickly. I am actually having vehicles in front of me moving over, thinking that I'm flashing my lights at them. Not only is this becoming very annoying, but I feel, it's unsafe as well. Please offer some insight that I can take back to the dealer.

  Go for the 10-spd. I have a 2024 3/4 ton and 1 ton dually. We are now at over 100k miles between the two. The 3/4 ton doesn't tow as much and I have had zero issues. The 1 ton tows a couple times a week, 10-16k depending on the machine I am moving. Both trucks are used for construction and also spend time at the farm, have been great. Had an issue with the 1 ton and GM replaced the valve body in the transmission, it was down for 3 weeks which sucked, but it was all covered. It tows great and I really like the 6.6 L8T. Maintenance has been easy, I do all oil and fluid changes myself. The front end is greasible, so make sure you keep everything lubed up. On our 2018 3/4 ton with the 6.0 I just had to use our unlimited powertrain warranty. I thought the warranty would never actually pay, but once they saw the engine was spotless inside at 180k and the only issue was a failed camshaft bearing, they paid 12k for a new engine. Always thought those warranties were a scam, but if you are diligent about maintenance and keep track of your records, they are great. Many of the oil changes were self performed, but I had all the receipts from buying the oil and filters, and had a log with the mileage I changed it at.

  Alright so this one ended up being a different TSB that was not related to the transmission at all. It was the O2 sensor wire that got too close to the exhaust and melted. I guess the 5v reference wire melted, shorted out and caused about 200 codes to populate and the truck to go into limp mode. https://static.nhtsa.gov/odi/tsbs/2024/MC-10253570-0001.pdf

  Would the best option be to use a local dealer? I'll be flying into town, most dealers I've called want to charge to do a used car inspection. Can get expensive if I'm comparing 3+ trucks on the same day, not to mention scheduling. All I see on CARFAX reports is "Engine/powertrain checked" or "Emissions system serviced" and on a few, "Transmission replaced" or "Valve body replaced" which is concerning. A lot of "Transmission Replaced" prior to 140k so I guess I'll have to plan for some extra cash in case of an emergency. Is it normal for the 10L80 to downshift hard and flare when coming to a stop? I've now experienced it enough (along with some rear end noise when test driving) that I don't know what's a normal 10L80 in non-sport or Tow-Haul mode. Some trucks downshifted cleanly, others lurched and jerked as the RPMs jumped around even in Normal mode.

  I'd go right back to the dealer. If I didn't get satisfaction there, I'd go to a different one. If not there, I'd contact GM. It's under warranty. It's their issue to fix.
