Complete 6L80E/6L90E overhaul in one box: friction plates, steels, sealing rings, piston seals, solenoid O-rings and pan gaskets for 2007-2017 GM trucks.
This overhaul kit is aimed at the 6L80E and 6L90E in the 2007-2017 GM lineup, the era of the Escalade 6.2L, the CTS and Camaro with the 6.2L, the STS 4.4L, and the Tahoe, Yukon, Silverado 1500 and Sierra 1500 on the second-generation platform. It is a friction-and-steel master kit: every clutch plate for the five packs, plus the overhaul seal and gasket set. What sets it apart from the other 6L80 kits we carry is how the soft parts are packed. The 1-2-3-4 and 3-5-Reverse clutch O-rings, the general seals and O-rings, the solenoid O-rings and the 2006-up shaft sealing rings each come in their own bag, so you can work drum by drum without sorting a pile of rubber on the bench.
In a 6L80 the TCM shifts by draining one clutch while it fills another, using pressure control solenoids to time the overlap. Worn frictions take longer to grip, and the controller compensates until it runs out of adapt range. That is why these units often flare on the 3-4 or 4-5 shift long before they slip outright. Replacing every friction and steel, along with the piston O-rings and Teflon rings that hold apply pressure, brings all five clutches back to the same baseline so the TCM can relearn them together.
Not every 6L80 slip is a dead clutch. GM's PIP5429A describes a 2-3 upshift slip or flare on 2010-2015 Camaros caused by air trapped in the 3-5-R clutch circuit when the car is cold, and the fix is a purge procedure, not a rebuild. GM bulletin 16-NA-130 covers no Reverse and no 2nd after an upper valve body replacement, traced to the wrong valve body version being installed. Rule those out, then check line pressure against the commanded value. Our 6L80 Camaro shift problems guide and 6L80 Escalade shift problems guide walk through the gear-by-gear checks.
Listed applications: 2007-2017 Cadillac Escalade 6.2L, 2007-2015 CTS 6.2L, 2007-2009 STS 4.4L, 2009-2013 Avalanche 5.3L, 2010-2015 Camaro 6.2L, 2009-2016 Silverado 1500, 2007-2016 Sierra 1500, 2009-2017 Tahoe, 2007-2016 Yukon and 2009-2014 Express 1500. The kit is built for the 2006-up 6L80E/6L90E design. Read the tag on the case to confirm you have a 6L80 (MYC) or 6L90 (MYD), and if your truck is a heavy-duty model or outside this range, send us the year and VIN before ordering.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No filter is listed for this version. It includes the frictions, steels, sealing rings, piston and clutch O-rings, solenoid O-rings, front and rear seals, valve body gaskets and cork pan gaskets. Buy a 6L80 filter with its neck seal to complete the job.
Both are on the listed fitment: 2007-2017 Escalade 6.2L and 2010-2015 Camaro 6.2L. Confirm the case tag reads 6L80 or 6L90 before you tear it down, and contact us with your VIN if anything looks different.
Possibly not. GM's PIP5429A attributes a cold 2-3 flare on 2010-2015 Camaros to trapped air in the 3-5-R circuit and calls for a purge procedure. Try that and an adapt reset first; if the flare persists hot as well, the clutches are the likely cause.
A filter and neck seal, any worn bushings, and any piston or housing that fails an air check. Inspect the pump gears and the 3-5-R and 1-2-3-4 housings for cracks before reassembly.
Yes. After filling with Dexron VI and checking level hot, reset the transmission adapts and run a fast learn so the TCM relearns clutch fill times on the new plates.
