Full overhaul kit for the GM 6T40E and 6T45E: frictions, steels, gaskets, seals and O-rings to rebuild a slipping or shuddering front-drive six-speed.
This is the complete-pack option for a Gen 1 GM 6T45E or 6T40E: friction plates, steel plates, the paper and rubber gasket set, lip seals, sealing rings and O-rings, sold under manufacturer reference ING-6T40E. It is aimed at the 2011 Chevrolet Equinox and Malibu 2.4L, the 2010 Captiva Sport, the 2010-2011 Cruze and LaCrosse and the 2008-2009 Pontiac G6 2.4L when the transmission slips, shudders on the converter clutch apply, or engages late once the fluid is hot. Because the steels are in the box, a builder who finds heat-blued or warped plates on teardown does not have to stop and source them.
The 6T45E is the higher-torque member of GM's small transverse six-speed family and shares its layout with the 6T40E. Each gear is a combination of applied clutches and a one-way clutch, so a pack that slips in one range usually shows up in two or three gears that share it. Every pack is a stack of alternating frictions and steels squeezed by a piston, and the steel side matters as much as the lining: a steel that has run hot loses its flatness and its surface finish, and a new friction pressed against it will glaze quickly. Renewing both halves of every pack, plus every seal that holds apply pressure, is what gives the rebuilt unit a fresh baseline instead of a mix of new and worn parts.
Not every harsh shift is a hard-parts failure. GM Preliminary Information PI0724B covers a harsh 2-3 upshift on throttle release in the 2011 Equinox, Terrain and Captiva 2.4L 6T45 and corrects it with a TCM calibration, so an otherwise healthy unit with only that complaint should get a software update first. Slipping across gears, burnt fluid and debris are different: that is clutch and seal wear, and a teardown is the fix. Set the fluid level hot before judging anything. Our 6T40 and 6T45 common problems guide covers the known faults by year, and the 6T40 valve body symptoms guide helps separate a worn valve body from worn clutches.
Listed fitment: 2010-2011 Buick LaCrosse 2.4L and 3.0L, 2010-2011 Chevrolet Cruze 1.4L and 1.8L, 2010 Chevrolet Captiva Sport 2.4L, 2011 Chevrolet Equinox 2.4L, 2011 Chevrolet Malibu 2.4L and 2008-2009 Pontiac G6 2.4L. These are first-generation units; GM's PI0604C describes the 2012 Gen 2 update, which changed the 4-5-6 clutch and removed a sealing ring, so a later unit will not match this stack. Running changes also happened inside 2011, and V6 applications should be checked against the transmission RPO code. Compare the plate count from your case with the kit, or send us your year and VIN and we will verify it. Browse the rebuild kit category page for 2012 and later kits.
Clean the case and every passage, then check the drums for scoring and spline damage before opening the kit; a 3-5-R drum with chewed splines needs replacing, and the 2008 6T40 clutch drum covers early units. Soak the new frictions in Dexron VI, air-check each pack as you build it, and set clearances with the selective plates. The front pump seal and the case-to-pump gasket are in the kit; GM's PI0950 revised the converter seal on units built before February 1, 2013, so seat the new seal square with the 6T40 pump seal installer set rather than a hammer and socket. If shift feel was a complaint, the 6T45 shift kit goes in during the same teardown. Fill with Dexron VI, set the level hot at the check plug, clear adapts and run the adaptive learn.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
This one includes steel plates along with the frictions, gaskets, seals, sealing rings and O-rings. The other 6T40E/6T45E master kit leaves the steels out for builders who plan to reuse them. If your steels are blued, warped or scored, this is the kit to buy.
Not necessarily. GM PI0724B addresses a harsh 2-3 on throttle release in the 2011 Equinox, Terrain and Captiva 2.4L with a TCM calibration. If the shift is the only complaint and the fluid is clean, update the software first.
It is listed for 2008-2011 applications. GM updated the family for 2012 with a revised 4-5-6 clutch and other changes, so compare your plate count with the kit or send your VIN before ordering for a later unit.
The listed shipping weight is about 11 lb in a 22 x 16 x 6 inch package, and it ships from the USA.
Dexron VI. Fill, run the engine through the ranges, and set the final level with the fluid hot at the level check plug, then run the adaptive learn with a scan tool.
