Ford F-250 Super Duty Transmission Fluid: Change Interval
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-11
When to change the transmission fluid on a 2020-2025 Ford F-250 Super Duty.
In short: Ford F-250 Super Duty transmission fluid: 10-speed: inspect ~10,000 mi; change ~150,000 mi normal, ~50,000 mi heavy towing/severe.
| Transmission Fluid interval | 10-speed: inspect ~10,000 mi; change ~150,000 mi normal, ~50,000 mi heavy towing/severe |
|---|---|
| Engine / drivetrain | 7.3L 'Godzilla' V8 gas (primary) or 6.7L Power Stroke turbo-diesel; 5W-30 (gas); TorqShift 10-speed auto |
| Model years | 2020-2025 |
Why it matters: Transmission fluid lubricates and cools the gearbox. "Lifetime fill" really means "lifetime of the warranty" — heat from towing, hills and stop-and-go traffic ages it much faster.
A drain-and-fill (not a flush) is the safe approach, especially on higher-mileage cars. Use ONLY the exact fluid spec for your transmission — the wrong fluid can ruin a CVT or automatic.
Ford F-250 Super Duty note: The 7.3L 'Godzilla' gas V8 is the primary engine; the 6.7L Power Stroke turbo-diesel differs sharply — far larger oil capacity, a fuel/water separator, and diesel fuel filters on their own (~every 20,000 mi) schedule. As a work truck, frequent towing/hauling pushes oil, transmission and coolant to the severe-service intervals — document service by duty, not just mileage.
