How much transmission fluid does a 2005 6.0 powerstroke take?
In the 2005 Ford Super Duty with the 6.0-liter Power Stroke, the automatic transmission uses the TorqShift 5R110W. The amount of ATF needed depends on the service you perform. The short answer: plan for roughly 14–16 quarts for a standard pan drop and refill, with about 18–20 quarts if you’re replacing the entire system, including the torque converter.
Understanding capacity by service type
Transmission fluid capacity varies with how you service the unit. Below are typical ballpark figures to guide planning and ordering parts and fluid.
- Pan drain with filter change (standard drain-and-fill): about 12–14 quarts (11–13 liters).
- Full drain and fill with new filter (pan drop and refill): about 14–16 quarts (13–15 liters).
- Complete system replacement including torque converter and lines (flush or full replacement): about 18–20 quarts (17–19 liters).
Note: Exact amounts depend on the truck’s configuration, prior maintenance, and whether you are performing a flush versus a simple pan drop. Always verify by checking the dipstick as you fill and top off to the correct level.
Practical tips and caveats
Use the fluid type specified by Ford for the 5R110W transmission in your year; many 2005 trucks call for Mercon SP or Mercon LV compatibility. If in doubt, consult the owner's manual or a dealership service bulletin and have extra ATF on hand to top off after the initial fill.
Summary
For a 2005 6.0 Power Stroke with the TorqShift 5R110W, plan on about 14–16 quarts for a standard pan drain and refill, and roughly 18–20 quarts for a complete system replacement including the torque converter. Always confirm the exact specification for your vehicle and top off to the correct level using the dipstick as a guide.
