6T70 Master Rebuild Kit 2013-2019, new and ready to install. Fits the 6T70. Ships fast from the USA.
When a 2013-2019 Chevrolet Traverse, Equinox, Malibu or Impala, GMC Acadia or Terrain, or Buick Enclave starts slipping in 3rd and 5th, loses reverse, flares on upshifts or comes back from the shop with a P0776 and a dark pan full of clutch material, the fix is no longer a solenoid or a fluid change. It is a teardown, and this new master rebuild kit puts the wear parts for that job in one box: friction plates, steel plates, seals and gaskets for the later 6T70, as the photo of the boxed kit shows. Buying the master version instead of a gasket-and-seal overhaul kit means you are not reusing tired clutch plates in a transmission you have already paid to take apart.
The 6T70 uses five clutches to make six forward speeds: the 1-2-3-4, 2-6, 3-5-Reverse, 4-5-6 and Low/Reverse packs. Every one of them depends on friction material, steel plates with the right flatness, and piston seals that hold apply pressure without leaking. A master kit addresses all three at once. It is the right choice for a high-mileage unit that has slipped or overheated, a transmission with clutch debris in the pan, or any rebuild where you want each pack measured and set up with new plates rather than gambling on used ones.
Check fluid level and condition hot, scan for codes, and look at the pan and filter area for clutch material and metal. A unit that still shifts cleanly with a pressure-related code may only need controls work. Our 6T70 rebuild cost guide explains what drives the bill, and the common problems guide separates kit-level failures from solenoid and valve body faults.
This kit is listed for 2013-2019 6T70 units, which is the Gen 2 era. ATRA's update notes are specific: the 6T70 with RPO M7W or M7U, and the 6T75 with M7V or M7X, got GM's major controls update for 2013, while vehicles with other RPO codes stayed Gen 1 until 2014 production. So a 2013 or early 2014 transmission may still be Gen 1, and the earlier Gen 1 master rebuild kit is the one to use. Kit contents vary by application, so before you order, read the RPO codes from the Service Parts Identification label or send us your year and VIN. The same Gen 2 kit is also listed for the 6T75, which shares the clutch layout. Everything else for this transmission is on the 6T70 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Only if it is a Gen 2 unit. In 2013 the update went to RPO M7W and M7U 6T70s; other 2013 and some early 2014 vehicles are still Gen 1 and need the 2007-2012 style kit. Check the RPO codes or send us your VIN.
An overhaul kit covers gaskets, seals and sealing rings. A master kit adds the friction and steel plates, so every clutch pack goes back together with new material.
P0776 on these units is usually the broken 3-5-Reverse wave plate. The kit supplies the wear parts for the rebuild, but inspect the 3-5-Reverse drum splines too, since damage there needs a new housing.
DEXRON-VI only. Check the level hot, at 180-200 F transmission fluid temperature, after the fast learn procedure.
The TCM lives inside the transaxle. After internal repair, run Service Fast Learn Adapts so the module relearns clutch fill, and reprogram if the module or transaxle was replaced.
