6T75 Master Rebuild Kit 2013-2019, new and ready to install. Fits the 6T75. Ships fast from the USA.
The 6T75 is the heavier-duty member of GM's 6T70 family of front-drive six-speed transaxles, and by the 2013-2019 model years it was carrying a lot of weight: three-row crossovers, larger sedans and tow-rated V6 applications. When one of these units starts slipping, flaring between gears or dropping clutch material into the pan, a piece-by-piece repair rarely holds. This GM master rebuild kit for 2013-2019 6T75 units is meant for the full overhaul: every clutch pack renewed and the whole case resealed in one job.
The 6T75 builds its six ratios from five clutches: 1-2-3-4, 3-5-Reverse, 4-5-6, 2-6 and Low-Reverse. There are no bands. Each clutch is applied by a piston fed through sealing rings and lip seals, and the transmission control module times each apply against fill volumes it has learned. When frictions glaze or seals harden, the module can no longer hit those targets, so you feel it as flare, bind or a harsh engagement. A master kit replaces the friction and steel plates plus the gasket and sealing set that every one of those circuits depends on. Drums, planetaries, the pump and the valve body are hard parts and are inspected and reused or replaced separately.
A master kit is the right call when the clutches are actually worn, not when a solenoid or valve body is misbehaving. Pull every stored code, check fluid level hot (GM specifies a fluid temperature of 180-200 F before reading the dipstick) and look at what is in the pan. Clean fluid with a shudder code usually means valve body work, not an overhaul. Our 6T70 and 6T75 common problems guide separates the soft-part failures from the controls failures, and the rebuild cost guide breaks down what a full overhaul involves so you can compare it with a replacement unit.
This kit is listed for the 6T75 from 2013 through 2019. The important detail inside that range is 2013 itself. GM released a major controls update (Generation 2) for the 2013 model year, but according to ATRA only 6T75 units with RPO M7V or M7X received it that year; other RPOs did not get the update until 2014 production. So a 2013 vehicle can carry either generation. Check the transmission RPO on the Service Parts Identification label, count the frictions in each pack if the unit is already apart, and send us your year and VIN if there is any doubt. The 6T70 version of this kit is listed separately as the 6T70 master rebuild kit 2013-2019, and all parts for this family are on the 6T70/6T75 transmission page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2013-2019, but 2013 is a split year. Only RPO M7V and M7X 6T75 units got the Generation 2 controls update for 2013; others stayed Generation 1 until 2014 production. Send your VIN and we will confirm which build you have.
No. A master kit covers the soft parts and clutch plates: frictions, steels, gaskets and seals. Drums, planetaries, the pump and the valve body are reused if they inspect good or bought separately.
Dexron VI. Check the level only at operating temperature, 180-200 F on the scan tool, with the engine idling on level ground.
Yes. Run Service Fast Learn Adapts with a capable scan tool so the module learns the new clutch fill volumes. Skipping it usually leaves harsh or flared shifts until the adapts settle.
That pattern with P0776 usually means the 3-5-Reverse wave plate broke. The kit renews the clutches, but inspect the drum splines and the reaction planetary for debris damage, because those hard parts are often hurt too.
