- Hemi 6.4
In tow/haul mode only 8th gear is locked out.
I had a 2018 6.4 with 4.10’s and now I have a 2021 6.4 with 4.10’s. There is no difference in fuel mileage from the 6 speed to 8 speed.
However, the 8 speed is better than the 6 speed when pulling. I have a 33’ fifth wheel that is 12,000 wet and it pulls well. There’s some good size hills where I’m at and the 6 speed would be in 3rd and the 8 speed is in 4th.
