Fuller RTO14613 13-Speed Transmission (Eaton Roadranger)
The Fuller RTO14613 is a proven 13-speed overdrive manual transmission from the Eaton Roadranger family, favored by fleets and owner-operators for durability, consistent shift quality, and long service life. It’s a strong fit for regional haul, linehaul, and vocational trucks that need close ratios for pulling power and an overdrive for efficient highway cruising.
Why Choose the RTO14613
- Versatile gearing: Split gears provide control on grades while overdrive lowers RPM at cruise.
- Roadranger pedigree: Known for robust shafts, bearings, and synchronizer design when serviced to spec.
- Serviceable platform: Widely supported with parts, manuals, and technician know-how.
- Reliable performance: Smooth range and splitter operation when air and linkage are set correctly.
Typical Applications
- Highway tractors and regional haul tractors
- Vocational trucks (dump, mixer, refuse, utility) needing both low-speed control and highway efficiency
- Linehaul units operating across mixed terrain and variable gross weights

Ordering & Fitment Help
Transmission builds vary by tag and previous service history. For the best match, have your unit tag photo ready, along with vehicle year/make/model, engine, axle ratio, and tire size. We’ll confirm the correct configuration and advise on any related parts (clutch, yoke, PTO cover, sensors).
Installation Tips
- Inspect mounts, clutch, linkage, and crossmembers; replace worn items while the transmission is out.
- Use Roadranger-approved lubricant and fill to the specified level.
- Set clutch brake and free-play per OEM procedure; verify air lines and electrical connections for range/split.
- Perform a road test through all gears under load; recheck for leaks and linkage adjustment after the first run.
