6R80 Transmission Master Rebuild Kit Ford F-150 Mustang

The 6R80 is the six-speed automatic Ford put behind almost everything with a Blue Oval on it from 2009 on: F-150, Mustang, Expedition, Explorer, Ranger, Transit, and the Lincoln Navigator. It is a stout unit, but heat and miles wear the friction plates and harden the seals, and once you get shudder, slip on the 3-4 shift, or a delayed engagement, you are into the whole thing. When you have it on the bench, you replace the soft parts as a set, not one at a time.

This master kit gives you the full clutch pack of friction plates and matching steels, the complete gasket and seal package, the rubber piston seals, sealing rings, and o-rings needed to close the case back up. It cross-references the common 6R80 overhaul numbers T18300D, T18302D, T183080D, and T183081D, so it lines up with what you are pulling apart. Everything is fresh, so you are not reusing a glazed friction or a swollen o-ring that puts you right back under the truck.

Fitment covers 2009-2014 F-150 (3.5, 3.7, 4.2, 4.6, 5.0, 5.4, 6.2L), 2005-2017 Mustang, 2009-2014 Expedition and Navigator 5.4L, 2007-2014 Ranger, and 2009-2018 Transit. Use fresh Mercon LV, coat the seals with assembly lube on the way in, and pay attention to o-ring orientation on the pistons. This kit carries the parts to send a worn 6R80 back together tight. Ships from the USA.
