Eaton has been engineering commercial vehicle drivetrains since 1911, and the Fuller name it has carried since the 1950s has been on more heavy-duty transmissions than any other in North America. Today that expertise reaches the market two ways: through Eaton's own global manual transmission, clutch, and aftermarket business, and through Eaton Cummins Automated Transmission Technologies, the 50/50 joint venture formed in 2017 that designs, builds, and supports the Endurant family of automated transmissions. Behind every one of those products is Roadranger, Eaton's dedicated commercial vehicle support network — extended protection plans, ServiceRanger diagnostic software, IntelliConnect remote diagnostics, technical training through Roadranger Academy, and a 24/7 technical hotline. When you spec an Eaton drivetrain, you're buying the support behind it as much as the hardware itself.
