10R80 Transmission Master Rebuild Kit Ford F-150 Mustang

The Ford 10R80 is the 10-speed rear-wheel-drive automatic Ford co-developed with GM (GM calls its version the 10L80). This master rebuild kit covers a full teardown: the complete friction clutch module, the matching steel plate set, and a precision overhaul gasket and seal kit. Fitment runs across 2017-2022 F-150 (3.0L, 3.3L, and 3.5L EcoBoost including the Raptor), 2018-2022 Mustang (2.3L EcoBoost and 5.0L GT), 2018-2022 Expedition 3.5L, 2019-2022 Ranger 2.3L, 2021-2022 Bronco 2.3L and 2.7L, and 2018-2022 Lincoln Navigator 3.5L. Manufacturer part number SNTRK-10R80.

The 10R80 usually lands on the bench for harsh or flaring 1-2 and 4-5 shifts and for shudder on torque converter lockup once the clutches glaze and the fluid breaks down. When the unit is apart, replacing every friction and steel and every seal in one pass is what makes a rebuild hold. Reusing a burnt clutch pack or a hardened seal is what brings a 10R80 back a second time.

This kit puts the frictions, steels, and soft parts in one box so you are not chasing individual seal part numbers across suppliers. Build to the factory clutch counts and clearances, set your endplay, and refill with Mercon ULV. This is a full teardown and reassembly, so professional installation is recommended rather than a driveway fluid service. Ships from the USA, in-stock items ship same day.
