I purchased a brand new 2023 Silverado with the 5.3 and 10 speed transmission in January 2024. At 23,000 kilometers I have had all lifters replaced, bank 1 cylinder head replaced, transmission replaced and I'm on my 3rd torque converter. The transmission still shudders, and the rpm needle has a major fluctuation. The dealership tells me that the truck is running normal and within parameters... That is their go to line when they failed to repair the truck and have no clue as to what is wrong with the truck! NORMAL AND WITHIN PARAMETERS!! GM knows that they are manufacturing and selling crap and they don't care! There needs to be a lemon law in British Columbia Canada, to protect customers when they are sold a piece of shit!
