6T50 Overhaul Kit 2006, new and ready to install. Fits the 6T50. Ships fast from the USA.
This is a first-generation overhaul kit for the GM 6T50 and its 6T40 and 6T45 siblings, packaged as part number S144002B (the 144002B Gen 1, without-pistons kit). It is listed here under 2006 because that is where the Gen 1 run begins, but the kit itself is cataloged for Gen 1 units built from 2006 through 2011. If you own an early Malibu, Equinox, Terrain, LaCrosse, Regal, G6, Aura or Vue with a six-speed that needs to come apart, this is the gasket and seal set for that earlier design, not the later Gen 2 parts.
In a Gen 1 6T50, clutch apply pressure travels from the pump through the case and the valve body to five clutch pistons. The early design also used pressure switches in the control solenoid body that report clutch apply to the TCM, and GM changed that layout for 2012, which is why Gen 1 and Gen 2 soft parts are kitted separately. This kit replaces the paper gaskets, lip seals, O-rings and sealing rings that keep those Gen 1 circuits tight. It ships without bonded pistons, so it assumes your pistons are reusable or that you are replacing them separately.
Most early 6T50 rebuilds start with the 3-5-R wave plate, so read our wave plate failure guide before assuming the problem is a leak. Our 6T40 common problems guide covers the other known Gen 1 issues and the checks that point to each one. Pull the pan and look at the debris: fine friction material and broken plate pieces mean the clutch packs need attention too, not just seals.
The kit is listed for Gen 1 6T40, 6T45 (MH7) and 6T50 units from 2006 through 2011, including North American applications such as the 2008-2011 Malibu, 2010-2011 Equinox and Terrain, 2008-2009 Pontiac G6, 2009 Saturn Aura and Vue, plus export Buick, Chevrolet, Holden and Opel models. A 2011 build can sit near the changeover, so do not go by model year alone. Our 6T40 identification guide shows how to tell Gen 1 from Gen 2; the quickest tell is whether the control solenoid body has pressure switches. If yours is a 2012-2013 Gen 2, use the 2006-2013 overhaul kit instead, which carries both gasket patterns. When in doubt, send us your year and VIN before ordering.

No. It is the Gen 1 kit, cataloged for 6T40, 6T45 and 6T50 units built 2006 through 2011. The listing year is where the Gen 1 range starts.
No. 2012-2013 units are Gen 2 with a revised solenoid body and clutch layout. Use the 2006-2013 overhaul kit, which includes Gen 2 gaskets.
No, this is the without-pistons version. Inspect your bonded pistons and replace any that are cracked or swollen.
The 3-5-R wave plate on early units, any burned frictions and steels, the filter, and any cracked bonded pistons. Refill with DEXRON VI and run an adaptive relearn.
Check for pressure switches on the control solenoid body and confirm the build date. If you are not sure, send us the year and VIN.
