2- 2023 duramax trucks both less than 60,000 miles one was in shop for month 2nd one still in shop over a month and waiting. Have driven 6 speeds never touched with milage in the 500,000 miles no problems and better fuel milage time to go back, because ford amd dodge went to more gears doesn't mean you need to match stick to what works
