6R80 Shift Kit 2006-14, new and ready to install. Fits the 6R80. Ships fast from the USA.
Most people searching for a 6R80 shift kit own a 2009-2014 F-150, a 2011-2014 automatic Mustang, or an Expedition or Navigator from the same years, and they are chasing one of three complaints: a buzz or quiver at highway-on-ramp speeds that feels like the driveline, upshifts that slip and flare once the truck is hot, or a thump as it coasts to a stop. This listing is the TransGo SK 6R80 kit in the blue box, TransGo's repair kit for first-generation (GEN1) valve bodies. TransGo rates it for 2006-14 Ford 6R60, 6R75 and 6R80 units, and on this page we focus on the 6R80 trucks and cars from that span.
The 6R80 is a clutch-to-clutch six-speed: there are no bands, and every shift is a timed hand-off between clutches A through E, with variable force solenoids metering the oil. All of that depends on a stable base pressure from the pressure regulator (PR) valve. In the GEN1 casting, the PR valve and its balance bushing wear the bore, oil leaks past, and the computer can no longer predict how fast a clutch will fill, so it adapts until it runs out of range. TransGo's answer is a hardened steel, two-piece PR valve with longer lands plus aluminum boost bushings, and a steel TCC regulator valve with two calibration springs so the converter clutch applies smoothly instead of hunting. New damper inserts and wire retainers are in the box because the originals flatten and snap with age.
Not every bad shift on these years is the valve body. A 2012-2013 Expedition or Navigator that launches in 5th, shows a wrench light and a zero speedometer is a known lead frame fault covered by Ford's TSB 13-6-8 and extended coverage program 19N01, and our 6R80 Expedition shift problems guide lays out how to tell them apart.
Read codes first. Open or short solenoid circuit codes, P0720 or P0722 output speed codes, or an intermittent drop to first gear point at wiring, not hydraulics. With those cleared, check the fluid level hot, then watch commanded versus actual gear and TCC slip on a scan tool. Steady slip numbers with the clutch commanded on, plus ratio codes, are the classic worn PR and TCC regulator pattern. Mustang owners can work through our 6R80 Mustang shift problems guide, which covers the same valve body.
This kit is GEN1 only. Ford changed to the GEN2 valve body for vehicles built after December 2014, so most 2015-and-later trucks need the TransGo SK6R80-G2 kit. The catch is the changeover: some 2014 and early 2015 units, and some replacement GEN1 valve bodies, carry the extra filter hole that makes them look like GEN2. Pull and measure the original PR valve; .495 in is GEN1 and fits this kit. Keep in mind that Ford updated the 6R80 for 2011, including the one-way clutch and a change in SSE solenoid resistance on builds after November 2010, so a used or swapped valve body may not match your build year. If in doubt, send us your year and VIN, or browse all 6R80 transmission parts.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. This is the GEN1 kit for valve bodies with the .495 in pressure regulator valve, generally 2006-2014 builds. The G2 kit is sized for the larger .514 in GEN2 valve, used on most vehicles built after December 2014.
Probably not. A 5th-gear start with a wrench light and a dead speedometer on 2012-2013 Expedition and Navigator is the lead frame fault Ford addressed in TSB 13-6-8 and extended coverage program 19N01. Fix the electrical side first.
Yes, as long as the valve body is GEN1, which is what those cars came with. Measure the original PR valve at .495 in to be certain, especially if the transmission or valve body has been replaced.
No. The valve body comes out with the pan off, so the kit goes in as an in-vehicle service. Expect to recover several quarts of fluid when the valve body comes out and refill with Mercon LV.
Only if they test bad or the valve body has very high mileage. If you reuse them, put each one back in the exact bore it came from, since the calibration bands differ between positions.
