Ford Bronco Sport Transmission Fluid: Change Interval
Compiled & reviewed by Nikolai Tsyrenov · Updated 2026-07-02
When to change the transmission fluid on a 2021-2025 (1st gen, Escape/C2 platform) Ford Bronco Sport.
In short: Ford Bronco Sport transmission fluid: 8-speed auto (Mercon ULV) ~150,000 mi; AWD PTU/rear-unit gear oil serviced under severe use.
| Transmission Fluid interval | 8-speed auto (Mercon ULV) ~150,000 mi; AWD PTU/rear-unit gear oil serviced under severe use |
|---|---|
| Engine / drivetrain | 1.5L EcoBoost turbo-3 (0W-20) or 2.0L EcoBoost turbo-4 (5W-30); 8-speed auto; standard AWD |
| Model years | 2021-2025 (1st gen, Escape/C2 platform) |
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 Bronco Sport note: The 1.5L 'Dragon' three-cylinder runs its oil pump off a wet belt submerged in the sump — strict on-time 0W-20 changes matter, because degraded oil can damage that belt; plan to replace it ~150k. Some early 1.5L units had a coolant-intrusion recall.
FAQ
How often should you change the transmission fluid in a Ford Bronco Sport?

Should I flush or drain-and-fill the transmission on a Ford Bronco Sport?
