10L80 Shift Kit 2017, new and ready to install. Fits the 10L80. Ships fast from the USA.
Read this first: the listing is filed as a shift kit, but the product is a 10L80 transmission rebuild kit for 2017 and later units. It combines a Transtec overhaul kit (the gaskets and seals), a set of BorgWarner friction plates, and replacement clutch pistons. It is built for the Silverado 1500, Sierra 1500, Tahoe, Suburban, Yukon or Escalade owner whose ten-speed is slipping, flaring, shifting harshly after every relearn, or has burnt fluid and is coming out for a full rebuild. It does not recalibrate the valve body the way a true shift kit does.
The 10L80 makes ten forward gears from four planetary sets and six clutches, and each gear holds several clutches applied at once. Shift timing is managed electronically, with very short overlap between the clutch coming on and the one letting go, so a pack with worn friction material or a piston that leaks pressure shows up quickly as a flare, a bind or a code. This kit replaces the three things that wear out together in a high-mileage or overheated unit: the friction plates, the piston seals and bonded pistons, and the gaskets and sealing rings that keep each clutch circuit holding pressure.
Many 10L80 shift complaints are not worn clutches. GM bulletin 22-NA-182 lists harsh shift, shudder and flare concerns where software, fluid condition and adaptive learning come first, and valve body wear can cause the same feel; our 10L80 harsh shift guide walks through that order. Check line pressure and solenoid operation as described in the pressure control solenoid guide. If the pan shows heavy friction debris and the slip persists after a relearn, the unit needs this kit.
The kit is listed for 2017 and later 10L80 transmissions, which covers the half-ton Silverado and Sierra, Tahoe, Suburban, Yukon and Escalade from the start of production. GM made running changes, including the Gen. 2 valve body update in late 2019, so compare your old pistons and plate counts with the parts in the box before assembly, or send us your year and VIN. It is not listed for the 10L90 or the Ford 10R80. More parts are on our 10L80 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Although it is listed as a shift kit, this is a 10L80 rebuild kit: a Transtec overhaul gasket and seal kit, BorgWarner friction plates and replacement pistons. It does not change valve body calibration.
2017-up GM 10L80 applications such as the Silverado 1500, Sierra 1500, Tahoe, Suburban, Yukon and Escalade. It is not listed for the 10L90 or the Ford 10R80. Send us your year and VIN if you want a fitment check.
They are not listed in the contents. Plan to inspect and replace steel plates and buy a new filter separately if your unit needs them.
Dexron ULV only. GM lists 8.1 quarts for a service fill; a fully rebuilt and dry unit takes more, so fill and check the level hot.
Yes. Run the GM fast learn with a scan tool once the fluid is between 167 and 185 degrees F, then road test so the control module adapts to the new frictions.
