cummins 5.9 with 5 speed allison

Will this system work with the new freightliner FRED with the 5.9 Cummins and a 5 speed.
Will there be a need for new programing?


Should Work

I have a Freightliner XCS chassis with an Allison 5 speed and VMSpc works fine. Transmission temperature doesn't read on my 1000 transmission, but yours possibly might if it is a 2000 series. Surely Freightliner didn't change their data format with the FRED.

The engine data is all there on the FRED. But no tranny data. There are already a few folks out there running SilverLeaf on their FREDs. The MPG data I've heard is pretty good - 10.4 mpg in mixed driving from one guy I trust.
