Hi,
I've been battling with a 80+ MPH high pitched whistle whistling. It was bad enough to make me hate my truck. As expected, reporting this to my dealer (and expecting them to find the root cause) was similar to banging my head against a wall.
I believe I've got it eliminated/narrowed down...
My 2024 Platinum 3.5 702A (non powerboost) does not skip any gears under light acceleration. It was built 10/24. This includes normal and also eco mode. Is anyone else seeing this change or do I have a fluke?
