RTO16908LL

MANUAL TRANSMISSION

The Eaton Fuller RTO16908LL is an 8-speed manual transmission designed for heavy-duty trucks that need both highway road speeds and extreme low-end torque for off-road or construction use. It includes two deep reduction (low-low) gears in forward and reverse, providing extra pulling power when starting heavy loads on steep grades. Replacement is typically necessary when internal parts like synchronizers, bearings, or gears wear out, causing hard shifting, grinding, or loss of drive.
