Ford 555E Backhoe Overview
The Ford 555E is a mid-size tractor-loader-backhoe (TLB) introduced in the late 1990s under the New Holland brand, following Ford’s merger with Fiat. It features a 4.5-liter diesel engine producing around 85 horsepower, a four-speed power shuttle transmission, and hydraulic controls for both loader and backhoe functions. With an operating weight of approximately 15,000 pounds and a dig depth of over 14 feet, the 555E was widely adopted by municipalities, contractors, and rental fleets.
Ford’s backhoe line, dating back to the 1960s, evolved through the 555A, B, C, D, and E series. The 555E was one of the last models before full integration into New Holland’s branding. Known for its mechanical simplicity and rugged build, the 555E remains in service across North America.
Symptoms of Reverse Gear Failure After Storage
A common issue reported by owners is the sudden loss of reverse gear after the machine has sat idle for several months. The backhoe may start and operate normally in forward gears, but fails to engage or move in reverse. This behavior suggests an electrical or hydraulic fault in the shuttle control system rather than a mechanical transmission failure.
Key Diagnostic Areas
In Arizona, an operator parked his 555E for six months during the off-season. Upon restarting, the machine moved forward but refused to reverse. After inspecting the shuttle lever and wiring, he found corrosion on the reverse contact terminal. Cleaning the contact with electrical cleaner and reseating the connector restored reverse function instantly.
This case highlights how electrical oxidation—especially in dry, dusty climates—can mimic serious mechanical failure.
Recommendations for Owners and Technicians
Loss of reverse gear in a Ford 555E after extended storage is often caused by electrical contact failure or solenoid malfunction—not internal transmission damage. With basic tools and a methodical approach, operators can restore full function and avoid costly repairs. The 555E’s design favors field serviceability, making it a reliable choice for long-term ownership when properly maintained.

Key Diagnostic Areas
- Shuttle Shift Contacts: The power shuttle system uses electric contacts to signal gear selection. Corrosion or oxidation on these contacts can prevent reverse engagement.
- Neutral Safety Interlock: A safety switch prevents gear engagement unless the machine is in neutral. If misaligned or dirty, it may block reverse activation.
- Solenoid Function: The transmission uses solenoids to control hydraulic flow to clutch packs. A failed reverse solenoid or broken wire can disable reverse gear.
- Fluid Condition: Old or contaminated transmission fluid may cause sticking valves or delayed clutch response. Check for discoloration or debris.
- Power Shuttle Transmission: A hydraulic transmission that allows shifting between forward and reverse without clutching.
- Solenoid: An electrically activated valve that controls hydraulic flow.
- Shuttle Lever: The operator control used to select forward, neutral, or reverse.

Recommendations for Owners and Technicians
- Clean Shuttle Contacts with Electrical Cleaner: Use non-residue spray and a soft brush to remove oxidation.
- Inspect Wiring Harness for Cracks or Rodent Damage: Long-term storage can attract pests that chew insulation.
- Test Solenoids with a Multimeter: Verify voltage and resistance to confirm activation.
- Flush Transmission Fluid if Overdue: Replace with OEM-spec fluid and inspect for metal particles.
- Cycle All Gears Before Storage: Prevent sticking valves by running the transmission through all ranges monthly.
