All 17 in-stock 2021 F-150 transmission fitments, grouped by engine and drivetrain. Every unit is the 10-speed automatic (10R80) but the calibration and torque converter differ by engine — text us your VIN if you are unsure which applies.
Why Buy a 2021 Ford F-150 Transmission from Auto Power Source
Every 2021 F-150 transmission we ship is pulled from a low-mileage donor truck, cataloged by VIN, and held in our climate-controlled warehouse pending sale. Our ASE-certified technicians shift-test every gear and run a full functional evaluation before any unit is cleared for sale.
The 2021 F-150 pairs the 10-speed 10R80 automatic with five different engines — 2.7L and 3.5L EcoBoost, 3.3L V6, 5.0L V8, and the 3.5L PowerBoost hybrid — and the calibration, torque converter, and 4x2-vs-4x4 output are not interchangeable across them, so VIN-matching is critical. Text your VIN and we will confirm the exact match before you order.

2021 F-150 Transmission Buying Guide
-
Match the engine to the transmission calibration. Every 2021 F-150 uses the 10-speed 10R80 automatic, but the valve-body calibration and torque converter differ by engine (2.7L / 3.3L / 3.5L / 5.0L) — match the ID tag (e.g. ML3P-7000-xx).
-
Specify 4x2 vs 4x4. The 4x4 units interface with a transfer case; the tailhousing and output differ from a 4x2 gearbox.
-
Hybrid vs non-hybrid. The 3.5L PowerBoost hybrid uses a modular hybrid transmission (MHT) — it is not interchangeable with the conventional 10R80.
-
Police package vs standard. Police-spec F-150 transmissions (ID ML3V-7000-RA) carry a distinct calibration from the retail units.
-
Always run the donor VIN if available. We provide it on request for any F-150 transmission in inventory to verify mileage and history.
Our ASE-certified technicians verify every one of these points against your VIN before any transmission ships.
