6R80 Shift Kit 2006-2014, new and ready to install. Fits the 6R80. Ships fast from the USA.
This kit is for the first-generation 6R80 valve body, the one in six-speed Ford trucks and cars built through 2014. Owners of a 2009-2014 F-150, a 2011-2014 Mustang GT or V6 automatic, or an Expedition or Navigator from those years usually find it while chasing a light-throttle shudder that feels like an out-of-round tire, hot upshifts that slur, or a clunk on the way down to a stop. The kit pictured is TransGo's GEN1 repair kit, sold under part number SK 6R80-A, which TransGo lists for 2006-14 GEN1 6R60, 6R75 and 6R80 units.
On the GEN1 valve body the pressure regulator valve is the smaller .495 in design, and it rides in a balance bushing. Both wear the bore, so line pressure leaks away and the computer's shift timing stops matching what the clutches actually do. This kit replaces that stack with a two-piece hardened steel regulator valve, a new orange spring, two aluminum boost bushings and an end cap with no identification grooves, which is how you tell it from the GEN2 parts. The converter clutch regulator valve and spring are swapped for a steel valve and a small white spring, the change that targets the 28 to 46 mph quiver. Six damper rubber inserts and four wire retainers are in the box too.
On these years, the electrical side fails often enough that it has to be checked first. The 2012-2013 Expedition and Navigator in particular had lead frame and speed sensor faults that cause 5th-gear starts and a wrench light; our 6R80 Navigator shift problems guide covers those bulletins. Ford also changed the SSE solenoid on builds after November 4, 2010, raising its resistance from about 10.5 to about 18 ohms, so a mismatched solenoid on a swapped valve body can set codes that look hydraulic. Our 6R80 shift solenoid symptoms guide shows how to test them. If the circuits test good, the level is correct hot and you still see slip with the converter clutch commanded on, the worn regulator bores are the likely cause.
This listing is for 2006-2014. Within that span TransGo's GEN1 kit fits the 6R60 and 6R75 as well as the 6R80, so it covers the earlier Explorer and Expedition six-speeds too. The catch is the end of the range: Ford's parts book puts GEN2 on vehicles built after December 2014, but some late 2014 trucks and some new replacement GEN1 valve bodies have the extra filter hole that makes them look like GEN2. Pull the old pressure regulator valve and measure it. A .495 in reading means this kit is right; .514 in means you need the 2015-2019 GEN2 6R80 shift kit. Send us your year and VIN if you are unsure, and see every part for this transmission on our 6R80 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Most 2014 trucks use the GEN1 valve body this kit fits, but some late 2014 builds and replacement valve bodies are the exception. Measure the original pressure regulator valve: .495 in is GEN1 and fits; .514 in is GEN2 and needs the 2015-2019 kit.
Yes. TransGo lists its GEN1 kit for 2006-14 6R60, 6R75 and 6R80 GEN1 valve bodies, all with stock bore sizes.
Not always. If the solenoids test good and mileage is moderate, the kit alone usually does the job. On valve bodies past about 140,000 miles TransGo recommends fresh solenoids as well, matched by calibration number on 2011-up units.
Yes. Leakage past a worn pressure regulator bore lets clutches slip during and after shifts, which the computer sees as ratio errors such as P0731 through P0734 and P0729.
Read every code, check the fluid level at operating temperature, and test the solenoid and speed sensor circuits. Electrical lead frame faults are common on these years and can mimic hydraulic problems.
