6R80 Shift Kit 2015-2019, new and ready to install. Fits the 6R80. Ships fast from the USA.
Built for the second-generation 6R80, this kit is what you want if your six-speed Ford is a 2015 or later: an F-150 before the ten-speed took over, a 2015-2017 Expedition or Navigator, or an automatic Mustang. The usual reason people go looking for it is a shimmy at light throttle somewhere between 28 and 46 mph, shifts that feel fine cold and sloppy hot, or a clunk as the truck coasts down. The kit pictured is TransGo's SK 6R80-G2, which TransGo lists for 2015-2019 GEN2 6R80 vehicles and the 6R100 from 2017.
Ford reworked the valve body for the 2015 model year. The pressure regulator valve grew from .495 in to .514 in, the separator plate switched to bonded gaskets, and the casting gained an extra filter port used by start-stop models, which also carry a small electric auxiliary pump. The wear point did not change: the regulator valve and its boost valve still polish the bore until line pressure drifts, and the converter clutch regulator still lets the clutch hunt at part throttle. The G2 kit replaces the regulator with a patented two-piece hardened steel valve, a new boost valve, a large white spring and a four-groove end cap sized for the GEN2 bore. A steel converter clutch regulator valve and small white spring follow, with six damper inserts and four bore plug retainers.
Check the VIN for open recalls first. In April 2026 Ford filed recall 26V-237 for about 1.39 million 2015-2017 F-150s built from March 2014 to August 2017, because a degrading lead frame can send a false range signal and cause an unexpected downshift. That is a wiring and software repair, not a valve body problem. Our 6R80 F-150 shift problems guide covers how to tell the two apart, and our 6R80 harsh shift causes guide explains relearn and solenoid issues that feel similar. If the recall is done or does not apply, the level is correct hot, and you have ratio or shift codes with no circuit faults, worn regulator bores are the likely cause.
This listing covers 2015-2019 6R80 applications with or without start-stop. TransGo's instructions note that Ford's parts book shows GEN2 on everything built after December 2014, yet some early 2015 trucks still left the plant with a GEN1-style regulator in a casting that looks like GEN2. So measure the original regulator valve before installing. A .514 in land is GEN2 and this kit fits. A .495 in land is GEN1 and needs the 2006-2014 GEN1 6R80 shift kit. The kit is designed for stock factory bore sizes only. Send us your year and VIN if you want a second check, or browse the 6R80 transmission parts collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. TransGo's G2 kit fits GEN2 6R80 valve bodies with or without start-stop. Start-stop units have an extra steel check ball and spring and a two-neck filter, so keep every small part in its original spot.
Measure the original pressure regulator valve. A .514 in land means GEN2 and this kit fits. A .495 in land means GEN1, which some early 2015 trucks still have, and you need the 2006-2014 kit.
TransGo lists the same G2 kit for the 6R100 from 2017 on. This listing is sold for the 2015-2019 6R80, so send us your year and VIN if you are fitting a 6R100.
Usually not. On 2015-2017 F-150s that pattern matches the lead frame recall 26V-237. Get the recall checked and the wiring diagnosed first.
Often not. TransGo notes that a long-running quiver can mean the converter also needs replacing, but shops that install the kit with fresh fluid report it usually clears the shudder on its own.
Shifts can feel firm or uneven for several drive cycles while the computer adapts. Drive normally with a mix of light and moderate throttle and the shifts should settle.
