6T70 Overhaul Kit 2013-2020, new and ready to install. Fits the 6T70. Ships fast from the USA.
Late-model 6T70 owners usually land here after a shop quote: a 2013-2020 Chevrolet Equinox, Malibu, Impala or Traverse, a GMC Terrain or Acadia, or a Buick Enclave or LaCrosse with a slipping first gear, a shudder on the 2-3 shift, or a leak that keeps coming back. This new overhaul kit is the gasket and seal set for that second-generation 6T70. The photo shows the bagged kit with its pan gasket on top, ready to reseal the unit once it is apart.
A 6T70 shifts by pressure alone. Each of its clutches is applied by a piston, and that piston only works if its seals hold. Fluid reaches the rotating clutches through sealing rings, and the case, pump and side cover are closed with molded gaskets. When those parts age, pressure leaks off between the solenoid and the clutch. The module sees slower apply times and adds more pressure and time to compensate, which is why a worn 6T70 often feels fine on a short trip and slips or flares once the fluid is hot. Replacing every seal in one pass resets the hydraulic side of the unit.
Scan for codes and check fluid hot. Pressure switch and solenoid faults inside the control module can imitate worn seals, so rule them out first. The Equinox shift problems guide covers the shudder and flare tests, and the Malibu common problems guide explains which failures need a teardown and which do not.
This kit is listed for 2013-2020 6T70 transmissions, the Gen 2 design. Transmission Digest documented a slip-and-delay-in-first complaint caused by a Gen 1 piston built into a Gen 2 unit; the two pistons have different apply finger heights. That is the reason to order by generation and not just by model name. GM phased Gen 2 in during 2013 and used it in every 2014-later unit, so a 2013 vehicle should be confirmed by build date and RPO code. A heavy-duty 6T75 takes its own kit. Send us your year and VIN if you are unsure, and browse the 6T70/6T75 collection for matching parts.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2013-2020 Gen 2 units. A 2012 and earlier 6T70 is Gen 1 and uses different pistons and seals, so order the Gen 1 kit for those years.
No, this listing is the 6T70. The 6T75 is the heavy-duty version with its own parts, so order the 6T75 kit if your RPO code shows a 6T75.
No. It is the gasket and seal overhaul kit. Add frictions and steels if the plates are glazed or the pan has clutch material.
Not by itself. GM traces that shudder on 2014-2019 units to valve body debris, so the valve body must be cleaned or replaced and the fluid flushed along with any reseal.
DEXRON VI, checked hot. After installation, clear the shift adapts and run the GM drive learn, or the unit can shift harshly from 1st to 2nd with no codes.
