10L80 Master Rebuild Kit 2017, new and ready to install. Fits the 10L80. Ships fast from the USA.
If your Silverado, Sierra, Tahoe, Suburban, Yukon or Escalade with the 10L80 has started to slip, bang into gear or throw clutch codes, and the teardown is happening anyway, this kit gives you every soft part for the job. It combines a professional overhaul kit with a complete OE friction plate set for the 10L80, the standard-duty member of GM's 10-speed family. Steel plates are not part of the kit, so plan to reuse good steels or buy them on their own.
The overhaul side covers the sealing: a three-piece bonded clutch piston set, four metal-clad seals, the pump rotor and slide seal kit, shaft sealing rings, the large outer pump O-ring, all clutch piston and housing O-rings and D-rings, rubber-coated pump bolt washers and the case seals for the pump and valve body. The friction side holds 28 plates: six for the D-clutch, three for the A-clutch, five each for the C-clutch and B-clutch, five flat E-clutch plates and four for the F-clutch. One set comes pre-soaked in ATF.
There are no bands in this transmission. Six clutches route power through four planetary gearsets, and the TCM swaps one clutch for another on every shift while three others stay applied. Because the 10L has no pressure sensors, the TCM leans on solenoid characterization data and speed sensor feedback to time each handoff. That makes clutch condition critical: a glazed or worn pack changes fill time, the TCM chases it with adapts, and the driver feels harsh or erratic shifts. The F-clutch works from fourth through tenth, so it sees highway duty, while the D, C and E clutches are applied across most of the gear range and take the most wear. The 10L90 version of this kit adds one D and one C plate and uses waved E plates, so do not swap kits between the two units.
Many 10L80 complaints come from the valve body, not the clutches. ATRA's GEARS diagnostic article lists sticking linear pintle solenoids and worn valve bores as common high-mileage findings, and GM's special coverage on rear wheel lockup describes a worn control valve with gradual pressure loss and code P0747. Check whether your truck falls under that coverage before paying for a rebuild. Our guides on 10L80 valve body wear and the recall and shift solenoid testing cover what to rule out, and the 3-4 clutch failure guide shows what a genuine clutch failure looks like.
Listed for 2017-on GM 10L80 10-speed automatics in cars, SUVs and pickup trucks. Check the RPO code on the service parts label; if it shows the 10L90, buy the 10L90 kit instead because the friction counts differ. If you are unsure, send your year and VIN and we will confirm.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
GM full-size trucks and SUVs such as the Chevrolet Silverado, Tahoe and Suburban, GMC Sierra and Yukon, and the Cadillac Escalade. Confirm by the RPO code on the service parts label or send us your year and VIN.
No. This is a master kit less steels: overhaul seals, bonded pistons and 28 friction plates. Reuse steels only if they are flat with no bluing.
No. The 10L90 uses one more D-clutch friction, one more C-clutch friction and waved E-clutch plates. Order the 10L90 kit for that transmission.
DEXRON ULV only. GM lists 8.1 quarts for a fluid change; after a rebuild with a drained converter you will need more, then set the level hot per the procedure.
Yes. Clear adaptive values and run the transmission service fast learn so the TCM learns fill times for the new clutches. Skipping it usually leaves harsh or slipping shifts.
Possibly. GM issued a recall and special coverage for 10-speed valve body wear tied to rear wheel lockup and code P0747. Check your VIN for open coverage before paying for a rebuild.
