Depends on the job. Those high revs mean I can get up to a pretty good speed in first.We were talking about how many gears you gasser boys need to get the job done…
My current truck with 4:10's and aisin pulls absolutely great but needs about 2k rpm to cruise a 70. The previous 3.73 truck with the 68 struggled a bit on grades with the same loads. Both HD transmissions are sometimes harsh shifting whereas i hardly noticed the zf shifting.
Hemi POWA!!!the ford 7.3 needs 4.30 gears and a 10speed to do what the 6.4 hemi can do with 8 gears and 4.10s keep that in mind
I wasn’t towing “heavy”, but my Hemi never had trouble doing 70+ up the passes in CO with my 31’ Airstream and 1000# of stuff in the bed! It did rev for it though, no denying that!Hemi POWA!!!
If they kept the gearing the same as the 6.4 8HP, then the axle ratio would actually have to go to a 3.55 to keep the final drive the same.Judging from my previous EcoDiesel, if it's up to the task i think the ZF would really shine and give Ram the clear edge over the competitors just from the better gear spacing and smoother shifting compared to either of the HD trany options. And a bonus if the final drive ratio was a bit higher to keep hwy cruising rpms down more.

The big downside was the ZF was nearly impossible to service with no easy way to check fluid levels. This issue would definitely need to be rethunk.
