I dont notice that specific whine in my 2022 Trailboss 6.2. I do notice that it is not a smooth quiet idle compared to the multiple 5.3 litres I've had. I do like the engine though. But seems a little noisy. The issue that is driving me crazy. I am having a couple of strange issues. I hear a prominent whine when dow shifting into lower gears and when down shifting it hunts for gears and have had it lurch and buck really bad. Especially if just driving normal or slowly. Also happens if I have to stop quickly in traffic or if turning into another road and starting to accelerate etc. It did it so bad the other day. I thought someone hit me in traffic. Is there a programming change for this. Thinking torque converter to transmission issue. The transmission to me got hotter than normal cruising in a car show this past summer. It was like 95 degrees and high humidity. Tranmission got to like 215 and was not towing. Truck just hit 17,000 miles as time of this post. Had 14k on it when transmission was a little warm.
