Complete 6L80E/6L90E overhaul kit with friction plates, steels, seals and gaskets for 2006-up GM trucks, SUVs and Cadillacs. Rebuild the whole unit.
This master rebuild kit is the one to pick when you are overhauling a 6L80E or the heavy-duty 6L90E and want frictions and steels in the same order as the seals and gaskets. It references the OE kit number A76L90 and covers the six-speed rear-drive units behind the V8s in 2006-up Silverado, Sierra, Tahoe, Yukon, Suburban, Escalade and Corvette, along with the 6L90E in 2500 and 3500 pickups and Express and Savana vans. Owners usually land here after a slipping 1-2 or 3-4 shift, a flare between gears, or a pan full of dark fluid and clutch material.
Both transmissions shift by handing torque from one clutch pack to the next, with no bands. Five clutch packs do all the work, so a single glazed pack or a piston seal that bleeds pressure shows up as a slip or flare the TCM keeps trying to adapt around. This kit renews the lip seals, sealing rings and gaskets that hold apply pressure, and replaces the friction and steel plates so the packs get their original holding capacity back. It does not include bushings, solenoids, the converter or valve body parts, which keeps it focused on the clutch and sealing side of the overhaul.
Do a fluid and pan inspection first, then check line pressure against commanded pressure. A healthy hydraulic system with burnt clutches is a rebuild candidate; a weak pump or worn pressure regulator has to be fixed as part of the job, or the new frictions will not last. The 6L80 Escalade common problems guide and the 6L80 pump failure guide walk through those checks.
The kit is listed for the GM 6L80, 6L80E, 6L90 and 6L90E from 2006 up, manufacturer number ING-TOR04501, OE kit reference A76L90. The 6L90 uses a longer case and heavier internals than the 6L80, so confirm the clutch counts in your unit match the kit before tearing in, especially on an HD truck or van. This kit does not fit the transverse front-drive 6T70 or 6T75. If you are not sure which unit you have, send us your year and VIN, and use our 6L80 parts collection for hard parts.
Soak the new frictions in Dexron VI, replace every piston lip seal and sealing ring, and measure clutch clearance as each pack goes back together. If any piston is cracked or the bonded rubber is lifting, a 6L80E/6L90 bonded piston set is the right companion. A filter is not part of this kit, so add an ATP B-239 filter and gasket kit, and inspect the bushings, the low sprag and the pump while the case is empty. Flush or replace the cooler, fill with Dexron VI using the check plug procedure, then reset adapts and complete a fast learn.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for the 6L80, 6L80E, 6L90 and 6L90E from 2006 up under OE kit reference A76L90. Count the plates in your packs on teardown to confirm the stack matches.
No. Bushings, the filter, solenoids and the torque converter are not part of this kit. Inspect those during teardown and order them separately.
Only if the converter is serviced too. Shudder usually comes from the converter clutch and fluid condition, so replace or rebuild the converter when you overhaul the unit.
No. Those are transverse front-drive six-speeds and share no clutch packs with the 6L80 or 6L90.
Dexron VI. Fill using the check plug procedure at operating temperature, then reset adapts and run a fast learn with a scan tool.
