usbusin Posted September 12, 2019 Report Share Posted September 12, 2019 Here is an interesting article I ran across about the development of "downspeeding" in the post 2010 engines. Interesting read. https://www.truckinginfo.com/155916/powertrain-specs-more-science-than-art Quote 2001 Freightliner FL70, Cat 3126b 300hp, 860 lb/ft, 6 speed manual Eaton/Fuller Motorhome body by Transport Designs (37 ft overall) Motorhome Specs and Pictures Our Music Ministry Link to comment Share on other sites More sharing options...
Moresmoke Posted September 14, 2019 Report Share Posted September 14, 2019 What’s old is new again. Went through this back in the early ‘90s with the family fleet. We were still running direct drive transmissions because you could net a bit more fuel economy. But driveshaft problems started showing up with faster rear ratios. Finally gave In and went to overdrives, which also had the benefit of slowing down reverse. Quote Link to comment Share on other sites More sharing options...
