Engineering:Roadranger transmission

Eaton Roadranger 18 speed with automated gearshift

The Roadranger transmission is a line of manual, and automated manual, heavy duty transmissions built by Eaton Fuller. They have found use in vehicles from multiple manufacturers all over the world. Using a combination of gear "ranges" and "splitters", different variations of number of speeds are possible, with 9, 10, 13, 15 and 18 speed variants of the Roadranger being common. The rugged design makes use of twin countershafts and constant mesh, unsynchronised gears.
