6T50 Clutch Module, new and ready to install. Fits the 6T50. Ships fast from the USA.
When a first-generation 6T50 has burnt its clutches, slips between gears or lost reverse, and you are going to split the case anyway, this listing gives you the clutch side and the sealing side of the job in one order. It is a master kit for 2008-2011 Gen 1 units in the GM 6T40, 6T45 and 6T50 family: an overhaul kit with the gaskets, metal-clad seals, lip seals and O-rings, a full set of friction plates, and a new filter. It suits the Chevrolet, GMC, Buick, Pontiac, Saturn, Saab and Daewoo front-drive and all-wheel-drive models that carried this six-speed in those years.
The 6T50 is the heavy-duty version of GM's 6T40 design, a transverse six-speed with no bands. Every gear comes from applying two of its five clutches, and the shifts are clutch-to-clutch: one pack releases while the next applies, timed by solenoids in the control module that bolts inside the case. That puts all of the work on the friction plates and on the piston seals that hold apply pressure. When a friction lining glazes or burns, the clutch cannot hold torque and the computer sees slip as a ratio error. When a seal hardens, the piston leaks off and the clutch it feeds slips even with good frictions. Replacing the frictions without the seals, or the seals without the frictions, is how a rebuild comes back, which is why this kit pairs them.
Start with the fluid level, which on this family is set at the check plug with the engine running and the fluid hot. Pull codes, then drop the pan. A single solenoid or circuit code with clean fluid usually points at the control module or valve body rather than the clutches. Friction dust, metal flakes or pieces of a wave plate mean the unit has to come apart. Our 6T40-family slipping guide walks through those checks, and the wave plate failure guide shows what a broken 3-5-R plate does to the rest of the transmission.
This kit is listed for Gen 1 6T40, 6T45 and 6T50 transmissions from 2008 to 2011, six-speed only. GM revised the family for 2012 with a new 4-5-6 clutch and other changes, so a 2012 or later unit may need different frictions and seals. Front-drive 6T50s carry RPO MHK and all-wheel-drive units MHJ; check the RPO label in the glovebox or door jamb and the ID tag on the case before ordering. Note that the main photo shows the overhaul gasket and seal set; the friction plates and filter ship with it. If you are unsure, send us your year, make, model, engine and VIN and we will confirm the match. Other parts for this family are in our rebuild kits category.

An overhaul kit (gaskets, metal-clad seals, lip seals and O-rings), a friction plate kit and a filter, for Gen 1 6T40, 6T45 and 6T50 units. Steel plates, bushings, pistons and hard parts are not included.
It is listed for 2008-2011 Gen 1 units. GM changed the family for 2012, including the 4-5-6 clutch, so check the RPO and case tag or send us your VIN before ordering for a later vehicle.
Yes, the kit is listed for Gen 1 6T40, 6T45 and 6T50 six-speeds from 2008-2011. Confirm your unit is a six-speed from that window.
DEXRON VI. Set the level with the engine running and the fluid hot at the check plug, not with a dipstick.
Yes. Clear the transmission adaptive values with a scan tool and run the fast learn or a full drive cycle so shift timing matches the new frictions.
