The F550 doesn’t get the 10 speed
The Ram 3500 pickup doesn’t get the Aisin. It previously got a Chrysler transmission. Ram now offering a ZF-8 in lighter Cummins trucks. Should be a very good transmission.
Dont know what the future transmission will be in the 3500-5500 chassis.
Have heard of troubles with Ford 10 speed.
No contest for me. The Cummins engine and the Ram truck are nicer and more capable. The HO Cummins is sick
Just went to the Ram build site and verified that the Aisin 6 speed is required with the HO Cummins. You cannot select the ZF 8 speed with either of the diesel power options. The 8 speed ZF is standard with the 6.4l Hemi.
I hope that an 8/10 speed becomes available at some point.
As I understand it there were early teething problems with the 10 speed however later builds have been trouble free ( so far).
