Master overhaul kit for the Gen 2 GM 6T70 and 6T75, the 2013-up transverse six-speed in the Traverse, Acadia, Impala, Malibu and SRX.
This master rebuild kit is built for the second-generation GM 6T70 and 6T75, the version with GM's revised controls package that arrived for the 2013 model year. It services units also tagged 6T70E and 6T75E in the Chevrolet Traverse, Impala, Malibu and Equinox, GMC Acadia and Terrain, Buick LaCrosse and Cadillac SRX, and it replaces kit reference K196900A (manufacturer part number MEI-AP-TMS-TOR01201). If your later-model crossover or sedan is slipping, flaring on the 2-3 or 5-4 change, or engaging harshly into Drive, this is the soft-parts package for the overhaul.
Every gear in the 6T70 comes from two of its five clutches applying together, and the Gen 2 control system learns how long each clutch takes to fill, running that learn in steady 3rd, 5th and 6th gear. Worn frictions and leaking piston seals throw those learned values off, which is why a tired Gen 2 unit feels inconsistent before it actually slips. This kit supplies the friction plates, steel plates, gasket set and the rubber, Teflon and O-ring sealing set for one complete overhaul. It does not include hard parts: drums, planetaries, the pump, the sun shell and the valve body are inspected and reused or bought separately, and the filter is a separate purchase.
On later units it is common to see shudder that is really a controls problem and slipping that is really a clutch problem, and they need different fixes. Pull codes, check fluid hot, and look at what comes out of the pan. On 2015-2017 Acadia, Enclave and Traverse, a harsh light-throttle 1-2 with no codes is often just unlearned shift adapts, covered by GM PIP5363B, and needs a drive learn rather than a rebuild. The Acadia shift problems guide covers that procedure, and the rebuild cost guide explains when an overhaul makes sense.
This kit is for Generation 2 units. Gen 1 soft parts (roughly 2007-2012) and Gen 2 soft parts are not interchangeable even when they drop in, because GM changed clutch stack-ups and sealing rings with the update. The 2013 model year is the trap: ATRA reports that only 6T70 RPO M7W or M7U and 6T75 RPO M7V or M7X units got Gen 2 in 2013, while others stayed Gen 1 until 2014 production. Read the RPO from the glove box label, count the frictions in each pack against the kit, and send your year and VIN if unsure. Earlier units need the Gen 1 master kit for 2007-2012. All 6T70 and 6T75 parts are on the 6T70 transmission page.
The kit ships in a box about 15.7 x 11.8 x 7.1 inches at roughly 9.5 lb.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Most 2014 and later units are Gen 2. For 2013, check the transmission RPO on the Service Parts Identification label: M7W or M7U on a 6T70 and M7V or M7X on a 6T75 are Gen 2. If unsure, send your VIN.
Yes. The listing covers Generation 2 6T70 and 6T75 units, including those tagged 6T70E and 6T75E.
Hard parts are not included: drums, planetaries, pump, sun shell and valve body. Buy the filter separately and plan to replace the case connector seal as well.
No. Those are Generation 1 units with different clutch stack-ups and sealing parts. Use the Gen 1 master kit for 2007-2012.
Fill with Dexron VI, check the level at 180-200 F fluid temperature, and run Service Fast Learn Adapts with a scan tool. Then power the module down and restart to complete the learn.
