How much to change transmission fluid on a Ford F-150?
Most Ford F-150s require roughly 9–12 quarts (8.5–11.5 liters) for a complete transmission fluid change, including a pan replacement and new filter; a simple drain-and-fill typically uses about 4–7 quarts (4–6.6 L). The exact amount depends on model year and whether the truck uses a 6-speed or 10-speed automatic, and whether you also flush the cooler lines or torque converter. Always verify with the owner's manual or a Ford dealer for your VIN.
What influences the quantity
The F-150 has seen multiple automatic transmission designs across generations. The total system capacity and the amount you actually drain during service vary with the setup, and the service method (pan drop, full replacement, or machine flush). This section outlines the main factors to consider.
Common transmission types in the F-150
Ford has used several transmissions in the F-150, notably the older 6R80/6R140 family and the newer 10R80 (10-speed). The 10-speed generally holds more fluid and often requires more fluid to complete a full replacement. Knowing your transmission code helps pin down the exact quantity.
Service options and approximate quantities
Plan around the following typical scenarios. The numbers assume you’re using Dexron VI automatic transmission fluid and that you replace the filter when you do a pan service. A full system flush with a machine can require more fluid.
- Pan drop and filter replacement: about 4–7 quarts (4–6.5 L).
- Full pan service with refill (no torque converter drain): about 8–11 quarts (7.5–10.5 L).
- Full system flush or machine-based replacement: about 12–14+ quarts (11–13 L) depending on the model and condition.
The actual amount in your truck will depend on the transmission design, whether you’re changing just the pan fluid or performing a complete system replacement, and whether any coolers or torque converter drains are included in the service.
How to get the exact figure for your vehicle
Check the owner’s manual maintenance section for the recommended ATF type (typically Dexron VI for Ford automatics), the exact system capacity, and the recommended service interval. When in doubt, reference your vehicle’s VIN with a Ford dealer or a qualified shop to confirm the precise quantity for your particular F-150.
Summary
In practice, a simple drain-and-fill usually uses 4–7 quarts; a pan replacement with a new filter typically consumes 8–11 quarts; a full flush can require 12–14 quarts or more. The exact amount depends on the transmission version (6R80/10R80) and the service method. Always verify with the manual or a professional for your VIN.
