2023 Silverado 5.3L with 10 speed doing the exact same thing , vibration when going certain speeds or going down slight incline , drive in L9 and truck runs great , but doesn't that defeat the purpose of DFM , they may as well just go back to the regular engine without DFM , has anyone had any luck figuring it out ? my 2017 Silverado had AFM and never had an issue thats why I traded up , wishing now would have kept it ! This exactly why people are switching to imports the quality isn't there anymore especially with the increase in price !
