FORD 5R110 Product Information

The Ford 5R110 transmission, commonly referred to as the TorqShift, is a heavy-duty automatic transmission used in Ford’s Super Duty trucks and vans. This robust and reliable transmission was designed to handle high torque outputs, making it an excellent choice for workhorses that demand durability and efficiency.

Overview and Design

The 5R110, introduced in 2003, was primarily paired with Ford’s Power Stroke diesel engines. It features a five-speed automatic system with an additional overdrive gear, often referred to as a six-speed due to its dual overdrive functionality. This advanced design allows the transmission to adapt to varying loads and driving conditions, enhancing performance and fuel efficiency.

Key specifications include:

• Gear Ratios:

  • 1st Gear: 3.09

  • 2nd Gear: 2.20

  • 3rd Gear: 1.54

  • 4th Gear: 1.09

  • 5th Gear: 0.71 (Overdrive)

  • Reverse: -2.88

• Torque Capacity: Designed to handle up to 1,000 lb-ft of torque, making it ideal for heavy-duty applications.

• Fluid Type: Mercon SP or Mercon LV, depending on the model year.

Applications

The 5R110 transmission has been used in various Ford vehicles, including:

• Ford F-250, F-350, F-450, and F-550 Super Duty models (2003-2010).

• Ford Excursion (2003-2005).

• E-Series vans equipped with Power Stroke diesel engines.

Notable Features

1. Tow/Haul Mode: Optimizes gear shifting to improve towing performance by reducing gear hunting and providing better engine braking.

2. Dual Overdrive Gears: Enhances fuel efficiency during highway driving and heavy loads.

3. Adaptive Learning: The transmission’s control module learns and adjusts shift patterns based on driving habits and load conditions.

4. Heavy-Duty Components: Reinforced clutches, planetary gearsets, and a robust torque converter to withstand high stress.

Common Issues and Maintenance

While the 5R110 is known for its durability, it is not without its challenges. Some common issues include:

• Shift Solenoid Failures: Can result in hard shifts or failure to engage certain gears.

• Torque Converter Problems: May cause shuddering or slipping under load.

• Overheating: Prolonged heavy towing without adequate cooling can lead to premature wear.

To ensure longevity and reliability, follow these maintenance tips:

• Regular Fluid Changes: Replace transmission fluid and filter every 30,000 to 50,000 miles, especially for vehicles used for towing or hauling.

• Use OEM Parts: Always use genuine Ford or high-quality aftermarket components for repairs.

• Check Cooling System: Ensure the transmission cooler is functioning properly to prevent overheating.
