The 2005 Ford Super Duty with a 6.0-liter Power Stroke diesel uses Ford’s TorqShift five-speed automatic transmission, the 5R110W. This pairing was standard for the 6.0L Power Stroke in the 2003–2007 era, replacing earlier four-speed units to handle higher diesel torque.
Below, you’ll find a concise overview of the transmission that Ford paired with the 6.0L Power Stroke in the 2005 model year, followed by maintenance considerations and a brief recap.
Transmission type and historical context
The 5R110W is a heavy-duty, electronically controlled five-speed automatic transmission developed for Ford’s Super Duty lineup. In the 2003–2007 window, Ford matched this TorqShift unit to the 6.0L Power Stroke to provide robust towing and hauling capability. The transmission is designed for diesel torque and is commonly paired with 2WD or 4WD configurations in the 250/350 series trucks.
Key features and considerations for this pairing are summarized below.
Before the list, note that the following points describe the core attributes and practical implications of the 5R110W as used with the 2005 6.0 Power Stroke.
- Heavy‑duty five‑speed automatic transmission known as the TorqShift 5R110W
- Electronically controlled with shift logic calibrated for diesel torque
- Includes Tow/Haul mode to optimize shifts under load
- Designed to handle the torque characteristics of the 6.0L Power Stroke
- Replaced the older 4R100 in this era to provide improved strength and gearing
In summary, the 5R110W is the standard transmission paired with the 2005 6.0 Power Stroke, offering compatible performance for heavy-duty use while requiring routine transmission maintenance to prevent common wear-related issues.
Maintenance and common issues
Keeping the 5R110W in good working order involves regular, Ford‑approved maintenance and attentive inspection for wear or leaks.
- Use the correct transmission fluid recommended by Ford and maintain proper fluid level and condition
- Regularly inspect for leaks around the pan, seals, and cooler lines
- Monitor for unusual shifting behavior, hard shifts, or slipping and address symptoms promptly
- Schedule routine transmission service, including filter changes where applicable and fluid flushes as recommended by Ford
Effective maintenance can extend the life of the 5R110W in a 2005 6.0 Power Stroke, but experienced issues may require diagnostic work, solenoid testing, or, in some cases, transmission refurbishment.
Summary
For the 2005 6.0 Power Stroke, Ford’s TorqShift 5R110W five-speed automatic is the standard transmission. It’s built to handle diesel torque and towing demands, but owners should adhere to prescribed maintenance practices to keep shifts smooth and prevent leaks or solenoid-related issues. If you’re buying a used 2005 Super Duty with the 6.0L, verify the transmission’s service history and look for signs of typical wear or leaks to assess long-term reliability.
What transmission does a 2005 6.0 powerstroke have?
5R110W Transmission
5R110W Transmission / ZF S6-750 Transmission.
What is the difference between 5R110 and 5R110W transmission?
The 5R110 has a torque converter without a lockup clutch. The 5R110W does have a lockup clutch, which can help improve efficiency and lower fuel consumption.
