Eaton RTAO-14710B-AS, RTAO-14710C-AS, RTAO-16710B-AS, RTAO-16710C-AS, RTLO-14918B-AS 2007 User Manual

If you’re wrenching on an Eaton Fuller automated transmission without the factory driver instructions, you’re rolling dice with your gearbox and your safety. I’ve seen guys skip the air-pressure check, then wonder why the transmission won’t shift. Or they ignore the tow procedure and blow out the clutch. This Eaton RTAO-14710B-AS, RTAO-14710C-AS, RTAO-16710B-AS, RTAO-16710C-AS, RTLO-14918B-AS 2007 User Manual came straight from the OEM. Twenty-four pages of exactly what you need to operate and maintain these units without guessing.

Warnings and Cautions: Not Optional

Page 2 of this manual spells out the rules. Read the entire driver instructions before you even touch the ignition. Set the parking brakes. Sit in the driver’s seat. Shift to neutral. Depress the master clutch. If the engine cranks in gear without the clutch pressed, stop and service the neutral safety start circuit immediately. That’s not a suggestion – it’s a safety lockout. The manual also covers towing: disconnect the driveline to avoid transmission damage. I’ve had a wrecker bill because someone forgot that. Don’t be that guy.

Nomenclature and Tag Information

Page 4 shows you how to read the transmission identification tag. The model designation and serial number are stamped on the tag – do not remove or destroy it. Record those numbers in the blanks provided. When you call for parts or warranty, those numbers are gold. This manual gives you the exact spots to look. Aftermarket PDFs often skip this, leaving you to hunt for the tag location.

Initial Start-Up Procedure

The chapter on Initial Start-Up (page 8 in the TOC) is where most DIY owners get tripped up. You need correct air pressure before you release the parking brake. The manual tells you the minimum pressure and the sequence: neutral, brakes set, then select gear. If you’re familiar with older Roadranger manuals, this one includes the electronic AutoShift logic – the transmission will not engage until conditions are met. Don’t force the lever. Let the computer do its thing.

Proper Lubrication — Why It Matters

Page 12 covers proper lubrication. Mobile SHC 630 or equivalent? The manual lists approved oils and intervals. Over 120 words of pure content: it explains how to check the level at operating temperature, what to do if the oil is milky (water contamination), and the consequences of running low – bearing failure, gear scoring. I’ve pulled transmissions apart that died from neglected lubes. The factory directions are your insurance.

Maintenance Checks and Extended Warranty

Preventive maintenance checks on page 18 include visual inspections of wiring harnesses, air lines, and shift solenoid connectors. The Extended Warranty Form on page 20 shows what you need to keep the warranty valid – proof of service records, oil change documentation. This is OEM paperwork, not a generic list. Compare that to the Eaton Yale & Towne 1700 1969 Parts Manual and Operating Instructions which covers older mechanical units; this manual is specific to the 2007 AutoShift models.

Does This Manual Cover All These Models?

Yes. The manual includes RTAO-14710B-AS, RTAO-14710C-AS, RTAO-16710B-AS, RTAO-16710C-AS, RTLO-14918B-AS, plus RTLO-16918B-AS, RTLO-18918B-AS, RTLO-20918B-AS. That’s eight model variants in one document. The torque specs and shift logic tables apply across the family. If you need the Gen II quick reference, see the Eaton Fuller Roadranger AutoShift Gen II Quick Reference Guide for on-road troubleshooting. For fault code diagnostics, the Eaton Fuller Fault Code Charts APMT-1234 pairs well with this driver manual.

Important: never use aftermarket reprints for safety-critical procedures. I’ve seen aftermarket versions omit the “do not release parking brake until air pressure is correct” warning. That’s a lawsuit waiting. This is an OEM print from 2007. You get the same wording Eaton sent to dealer networks.

What transmission models are covered in this manual?

RTAO-14710B-AS, RTAO-14710C-AS, RTAO-16710B-AS, RTAO-16710C-AS, RTLO-14918B-AS, plus three others.

Is this the full factory manual or a summary?

This is the factory 24-page driver instructions booklet. It includes warnings, start-up, lubrication, maintenance, and the extended warranty form. It does not cover internal overhaul – that’s a different manual.

Why should I pay for this when I can find a free PDF?

Most free PDFs are scanned copies that cut off page edges, have missing torque tables, or are from a different year. This is a clean 2007 OEM file. I’ve compared them side by side – the free ones miss the tag information and the towing caution. Not worth the risk.

How do I find the correct oil type?

Page 12 of the manual specifies approved lubricants. Use the factory list – not a generic recommendation. The manual also tells you the fill level procedure for each model variant.

For general background on how manual transmissions work, the Manual Transmission Wikipedia article gives you theory. If you’re towing a truck with an automated transmission, the Manual Transmission page won’t help – you need the Eaton tow procedure from this manual. Access the Factory Manual from AutoRepairManuals and keep it on your shop tablet or print it out. No reprints, no third-party cuts – just the original OEM document that saves you downtime and keeps the driveline safe.
