6T70 Overhaul Kit 2013-2019, new and ready to install. Fits the 6T70. Ships fast from the USA.
A 2013-2019 6T70 that leaks from the case, hesitates going into gear first thing in the morning, or slips once it is hot has usually reached the point where the seals are the weak link. This new overhaul kit is the full gasket and seal set for the later 6T70: the photo shows the loose kit laid out, with the pan and case gaskets, valve body area gaskets, rubber piston seals, sealing rings and the small O-rings and plugs that a teardown disturbs. It suits the V6 Chevrolet Equinox and GMC Terrain, the 3.6L Impala, and the Traverse, Acadia and Enclave built with the lighter 6T70 rather than the 6T75.
The 6T70 makes six speeds with five clutches, and it has no shift valves to soften a bad shift. The TEHCM commands each clutch directly, so shift quality depends on every piston building and holding exactly the pressure it is told to. Old seals that have taken a hundred thousand heat cycles get hard and shrink, and a piston that leaks a little applies late and slips a little. The computer learns around some of that until it cannot. This kit renews every seal and gasket at once so each circuit starts from zero leakage, which is what lets the adaptive shift learning set up correctly after the rebuild.
Pull codes, note the RPO codes, and check the fluid hot. If the fluid is clean and the problem is a cold-only delay or a leak, a reseal is likely enough. If the pan magnet is furry with clutch material, plan on frictions and steels as well. The Equinox shift problems guide and the Impala common problems guide both walk through separating seal and clutch faults from solenoid and valve body faults on these later trucks.
This kit is listed for 2013-2019 6T70 units, the Gen 2 era. The catch is the changeover year. ATRA explains that the 6T70 with RPO M7W or M7U got the Gen 2 controls update for 2013, while other RPO codes stayed Gen 1 until 2014 production. If your 2013 or early 2014 vehicle is Gen 1, the early 6T70 overhaul kit is the closer match. A separately listed 2013-2020 6T70 overhaul kit covers the same generation from a different maker. Gasket and seal sets differ by generation, so match the RPO code or send us your year and VIN. Every 6T70 part we carry is on the 6T70 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It fits if that transmission is a Gen 2 6T70 (RPO M7W or M7U). Some 2013 and early 2014 units were still Gen 1. Read the RPO label or send us your VIN and we will confirm.
Gaskets, rubber piston seals, sealing rings and O-rings for a rebuild, as shown in the photo. Clutch frictions, steels and the wave plates are not part of an overhaul kit.
Only if the slip comes from pressure leaking past worn seals. If the frictions are burned or the 3-5-R wave plate is broken, you need those parts as well. Check the pan for clutch material first.
Yes. The internal filter is not a routine service item on the 6T70; it is replaced when the unit is opened for repair, so a reseal is the time to do it.
DEXRON-VI, checked hot. After the rebuild run Service Fast Learn Adapts with a scan tool and let the TCM power down before driving.
