How many quarts of transmission fluid does my F350 take?

Typically 12–16 quarts for a full automatic transmission service on most Ford F-350 Super Duty trucks, and about 9–12 quarts for a simple pan drop and fill. Exact capacity depends on the specific transmission model and year, as well as whether the torque converter is drained during service.

The question is nuanced because Ford has used several automatic transmissions in the F-350 across different generations. The safest route is to confirm the exact specification for your exact truck by checking the owner’s manual, the official Ford service data for your VIN, or consulting a dealer or qualified shop.

What determines your F-350's transmission fluid capacity

Before you refer to numbers, it helps to know what can change the amount you need to add. The transmission model, the service method (pan drop vs. full flush), and whether the torque converter is included all affect the total fluid required.

• Identify the transmission model and year (common examples include 5R110W and 6R140 TorqShift). Different generations have different capacities.


• Decide whether you’re performing a pan drop and fill or a complete drain-and-flush (which may require draining the torque converter).


• Check the official capacity specification for your exact configuration using the owner's manual or Ford’s service data for your VIN.

Knowing the precise specification avoids underfilling or overfilling, both of which can impact transmission performance and longevity.

How to determine the exact amount for your F-350

Follow these steps to arrive at the correct quantity for your vehicle and service type.

• Locate the correct transmission capacity for your year and model in the owner’s manual or Ford's official service data using your VIN.


• If doing a standard pan drop and fill, prepare for roughly 9–12 quarts, depending on whether you replace the filter and the exact pan capacity.


• If performing a full drain including the torque converter (a more thorough flush), budget about 12–16 quarts, depending on the transmission design.

Use the recommended fluid type specified by Ford for your model year (the manual or dealer guidance will confirm whether Mercon V, Mercon SP, or another specification is required).

Summary

In short, the exact number of quarts for an F-350 transmission depends on the specific automatic transmission model and the service you choose. To be precise, check your VIN-based Ford specifications or the owner’s manual, and prepare for a range that typically spans about 9–12 quarts for a simple pan drop and fill, or 12–16 quarts for a full drain-and-fill including the torque converter. When in doubt, consult a Ford dealer or a trusted shop for the exact capacity for your truck.

How many quarts of transmission fluid does a Ford F350 take?

The amount of transmission fluid for a Ford F-350 depends on the model year and transmission, but it ranges from about 8 quarts for a pan drop service to over 18 quarts for a full, dry fill. For a typical pan and filter service, expect to need between 8 and 17 quarts, while newer 10-speed transmissions require approximately 18.2 quarts for a dry fill. Always consult your owner's manual or the correct service manual for the precise amount and fluid type. 
Capacity by transmission type

• 6R140 TorqShift 6-Speed (2011-2019):
  • Dry fill: Approximately 16.3–17.4 quarts 
  • Pan and filter service: Around 8–8.5 quarts 
• 10R140 TorqShift 10-Speed (2020+):
  • Dry fill: Approximately 18.2 quarts 
  • Pan and filter service: Around 14–15 quarts 
• 4R100 4-Speed (older models):
  • Total fill: About 17.6 quarts 
• 7.3L Diesel (older models):
  • Pan and filter service: Around 7–8 quarts 
  • Total fill: Around 12–14 quarts 

Important considerations

• Service type: A full "dry" fill capacity is for a brand-new or completely drained system. A standard service involving a pan and filter change will require less fluid. 
• Torque converter: Older models may have a drain plug on the torque converter, which holds an additional 6 quarts of fluid. If you drain the converter, your total fluid requirement will be higher. 
• Fluid type: Always use the specific fluid recommended by Ford, such as Mercon LV or Mercon ULV, depending on the transmission model. 

What kind of transmission fluid does a 6.7 Powerstroke take?

The 6.7 Powerstroke transmission fluid type depends on the model year, but generally requires either Motorcraft MERCON LV for 2011-2019 models (6R140 transmission) or Motorcraft MERCON ULV for 2020-2025 models (10R140 transmission). It is crucial to use the correct fluid as recommended by the manufacturer, and other fluids could cause damage.

2011-2019 6.7L Powerstroke (6R140 Transmission) 

• Fluid Type: Motorcraft MERCON LV Automatic Transmission Fluid (XT-10-QLVC)
• Specifications: WSS-M2C938-A 

2020-2025 6.7L Powerstroke (10R140 Transmission) 

• Fluid Type: Motorcraft MERCON ULV Automatic Transmission Fluid 

Important considerations

• Use the correct fluid: Always use the specific fluid recommended for your truck's model year to avoid transmission damage. 
• Transfer case fluid: The transfer case on these trucks typically uses MERCON LV fluid. 
• Check your owner's manual: Refer to your owner's manual for the most accurate and definitive information for your specific vehicle.

How many quarts of transmission fluid goes in a 350 turbo?

A Turbo 350 (TH350) transmission holds approximately 4 quarts for a standard pan fluid change, but a complete dry fill with a torque converter will require around 12 to 13 quarts. The exact amount depends on whether you are doing a simple fluid change or a full rebuild and the type of pan installed (stock or deep aftermarket). 
Fluid capacity by service

• Standard filter change: Start with about 4 quarts, then run the engine, shift through the gears, and check the dipstick, adding more as needed to reach the "full" mark. 
• Complete dry fill (new build): Approximately 12 to 13 quarts are needed when the transmission and torque converter are completely empty. 
• With a deep aftermarket pan: A deep pan can add 3 or more quarts of capacity to the transmission, so the total will be higher than the standard 12-13 quarts. 

Important tips

• Fill the torque converter: When performing a full refill, always fill the torque converter with fluid before installing it to prevent damage and ensure proper operation. 
• Check the dipstick: After refilling, start the engine, run it, cycle through all the gears, and then check the fluid level on the dipstick while the engine is running. Add fluid as necessary to reach the "full" line. 
• Use the correct fluid: Older TH350 transmissions typically require Dexron III or a fluid with similar specifications. Check your vehicle's manual or with the transmission builder for specific recommendations, as newer fluids may not be compatible. 

How much transmission fluid does a 6.7 powerstroke take?

A 6.7L Powerstroke transmission typically holds between 16.3 and 18.2 quarts of fluid, depending on the year and specific transmission (6R140 or 10R140). A standard drain and refill with a filter change requires less fluid, around 7 to 10 quarts, because not all the old fluid can be removed from the torque converter and cooler lines. 
Fluid capacity by transmission type

• 6R140 (Six-speed, 2011-2019): Total capacity is about 17.4 quarts, but a typical drain and refill requires approximately 7–10 quarts. 
• 10R140 (Ten-speed, 2020-2025): Total capacity is about 18.2 quarts, though a drain and refill will be less. 

Important considerations

• Total fill vs. drain and refill: The total capacity is the amount of fluid the transmission holds when completely empty. A standard service will not remove all the old fluid, so you will need less. 
• Fluid type: Use the fluid specified for your truck's model year, such as Mercon LV for the 6R140 or Mercon ULV for the 10R140. 
• Safety first: Always refer to your owner's manual for the most accurate information and follow all safety precautions when working on your vehicle.
