6T70 Clutch Module, new and ready to install. Fits the 6T70. Ships fast from the USA.
When a Traverse, Equinox, Impala, Acadia or Enclave starts slipping after the shift, flaring the engine between gears, or burning its fluid dark, a rebuilder opening the 6T70 usually finds glazed or thin friction plates. This new GM-branded clutch module is a set of 6T70 friction plates for that repair. The photo shows the plates themselves, in more than one diameter, so it is built to restock the frictions in the unit rather than a single pack.
GM built the 6T70 around clutch-to-clutch shifting. ATRA's introduction lists five clutches and one one-way clutch, two on/off shift solenoids, five pressure control solenoids and a single accumulator, with no shift valves. Each shift is timed electronically: the module ramps pressure off one clutch while ramping it onto the next, and it watches pressure switches and turbine speed to see whether the handoff landed. That system is precise, but it depends on friction plates with full lining. As linings wear, piston travel grows, the apply arrives late, and the overlap between the releasing and applying clutches turns into a moment of neutral. That is the flare drivers feel. New frictions put the stack height back where the computer expects it.
Rule out the cheap causes first. Low fluid and failed pressure switches in the TEHCM can mimic slip, and Sonnax notes the switches fail often enough to set P0752, P0872, P0877 and P0989 on their own. Check the level hot, scan for codes, and look at shift adapt values: one clutch that keeps learning more pressure is the pack that is wearing. Then drop the pan and look at what is on the magnet. Our 6T70 3-4 clutch failure guide explains which pack causes which symptom, and the Impala and Equinox common problems guides list the failures by vehicle.
This listing names the 6T70 but not a year range, and that matters because the 6T70 changed in 2013. Transmission Digest documents that generation 2 parts entered selectively in the 2013 model year and every 2014-and-later unit is Gen 2, with thinner 1-2-3-4 frictions (.058 in. against .061 in. for Gen 1) and a taller apply piston. Before you order, measure a 1-2-3-4 friction from your unit with a micrometer and count the plates in each pack, then compare. If you would rather not guess, send us the vehicle year and VIN and we will check it. If you already know your unit is a 2007-2012 Gen 1, the 2007-2012 clutch module is listed for those years. All 6T70 and 6T75 parts are on the 6T70/6T75 collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The listing covers the 6T70 without a year range. Gen 1 (2007-2012) and Gen 2 (2013-up) use different 1-2-3-4 friction thickness, so measure your old plates or send us the year and VIN before ordering.
It is a set of friction plates. Steels, piston seals, gaskets and the wave plates are separate. Reuse steels only if they are flat and not blued.
Often, if the pan shows lining material and adapt values show one clutch climbing. If the fluid is low or a TEHCM pressure switch has failed, fix that first; new frictions will not cure a hydraulic or electrical fault.
Dexron VI. GM specifies it for the 6T70 family, and soak the frictions in the same fluid before assembly.
Yes, ideally. Clearing the adapts and running the shift relearn gives smooth shifts right away. Without it the module keeps compensating for clutches that are no longer worn.
