Eaton RT-11109A-AT, RT-13109B-AT, RT-11109A-ATR, RTO-13109B-ATE, RT-11109A-ATS 2007 Troubleshooting Manual

Aftermarket PDFs get you halfway then leave you chasing a ghost code. I’ve seen techs swap solenoids on a hunch because some online guide skipped the electrical pretest. That’s billable hours down the drain. This 194-page Eaton RT-11109A-AT, RT-13109B-AT, RT-11109A-ATR, RTO-13109B-ATE, RT-11109A-ATS 2007 Troubleshooting Manual from Eaton is the factory file – no third-party guesswork. If you’re working on any of these Fuller automated transmissions, you need the real fault isolation procedures, not a rewritten summary.

Section 1: Diagnostics Procedure and Fault Codes

First thing you’ll hit is the diagnostics procedure starting on page 1-2. Eaton spells out how to retrieve and clear fault codes in the Driver Information Display. The Fault Code Isolation Procedure Index (page 1-8) organizes every code by symptom, so you’re not flipping through 50 pages hoping to find “System Code 72, Failed to Select a Rail.” Driving techniques are covered too – page 1-4 explains how the transmission behaves during a power-up sequence. This matters because a driver-induced fault looks a lot like a hardware failure.

Electrical Pretest on Page 2-1

Before you start chasing component codes, Eaton demands an Electrical pretest. Page 2-1 lists the volt/ohm meter (Eaton 5505027) and the pneumatic pretest on page 2-3. I’ve watched guys skip this step and waste a day replacing an ECU that was fine – the problem was a low voltage condition. The manual walks you through checking system voltage and verifying power-up sequence. If you don’t have a Pro-link main with the Heavy Duty Multi-Protocol Cartridge, buy one. Eaton lists the MPSI tools on the suggested tools page. You’ll need a 0-300 PSI hydraulic gauge, a 0-100 PSI hydraulic gauge, and a 0-100 PSI air gauge. No compromises.

Component Code 21 – Interrupt Solenoid Coil

One common headache: Interrupt Solenoid Coil faults. This manual gives you the exact resistance check, the supply voltage test, and the location of the coil in the valve body. You follow the steps on page 2-16 and you know if it’s a bad solenoid, a wiring short, or a bad ECU drive. There’s no “try this and maybe it works.” The same structured approach applies to every code: Component Code 22 Lockup/Bypass Solenoid, Component Code 34 Throttle Position Sensor, System Code 71 Stuck Engaged, and beyond.

Using the Suggested Tools – Factory Required

Eaton lists specific part numbers for a reason. The volt/ohm meter (5505027), Pro-link main (MPSI 104004), and the MPC Eaton Systems Software (805001) are the only way to pull the proprietary fault codes. You can’t use a generic scanner and expect to see RTO-13109B-ATE gear position sensor data. This manual tells you how to interpret every data parameter from the ECU. The related publications on page 2 include the Service Manual (TRSM-0020) and Driver Instructions (TRDR-0020). If you need parts, grab the Illustrated Parts List – Eaton TRIP-0023 for 11109 series, TRIP-0025 for 13109.

3 Reasons to Choose OEM Documentation

First: the fault code isolation tables in Section 2 are built from actual transmission test data, not a weekend engineer’s guess. Second: the torque specs and sensor clearances are missing from aftermarket knock-offs – you need those to avoid stripping a shift yoke. Third: safety warnings for towing and low air pressure are printed right on page 2. Aftermarket reprints often skip the “block the wheels” warning because they assume you know. You’d be surprised how many people skip it. Stick with factory.

Does this manual cover the RT-11109A-ATR?

Yes – RT-11109A-ATR is listed on the cover and in the fault code procedures.

What electrical tests are in this manual?

There is a full Electrical Pretest on page 2-1 covering system voltage, power-up sequence, and sensor resistance checks. Component Code 33 (System Voltage) on page 2-36 is a dedicated procedure for low-voltage faults. You’ll also find throttle position sensor tests, solenoid coil resistance, and ECU data link diagnostics. If you have a wiring issue, this manual walks you through the pin-out verifications using the Pro-link tool.

This isn’t a quick reference card. It’s the binder Eaton sent to dealers in 2007. If you’re dropping the transmission pan to replace a solenoid, you want the factory test before you spend the cash. Access the Factory Manual and keep it on your bench next to the VOM.
