6T40 Clutch Module 2008-2013, new and ready to install. Fits the 6T40. Ships fast from the USA.
Early 6T40 transmissions have earned a reputation. The 2008 to 2011 units in the Malibu, Aura, Equinox, Terrain and first-year Cruze are well known for broken 3-5-R wave plates (especially the 2008 and 2009 builds), lost reverse and burnt clutches by the time they reach a shop. If you are rebuilding one of these first-generation units, this is the friction side of the job: a Raybestos HT (Hybrid Technology) friction clutch pack module, Raybestos catalog number RHT96-246, listed here for the 6T40 and 6T45 from 2008 to 2013. It is made in the United States.
Raybestos lists this module for the Gen 1 6T40 and 6T45 with fourteen frictions: four for the 1-2-3-4 and 2-6 clutches, four for the 4-5-6 clutch, three external-spline frictions for the 3-5-Reverse clutch, and three for Low/Reverse. The 4-5-6 and Low/Reverse plates use HT material and the others are a high-energy material. Each of those five clutches works in more than one gear. Third, for example, is 1-2-3-4 plus 3-5-R, and reverse is 3-5-R plus Low/Reverse, so a single worn pack takes out a whole pattern of gears. Re-lining all five at once is the standard approach on a high-mileage Gen 1 unit, because the packs share the same burnt fluid and worn out together.
Gen 1 6T40s have control-side failures that can look like clutch slip. The pressure switches built into the control solenoid assembly can fail, and a damaged filter plate on early Cruze units has been tied to a flare toward neutral on the 1-2 shift. Read the codes, check the fluid hot at the check plug, and note exactly which gears misbehave. Our 6T40 common problems and fixes guide separates the clutch failures from the control failures, and the speed sensor guide explains how a bad sensor can trigger slip codes on a healthy unit.
Raybestos catalogs RHT96-246 for Gen 1 6T40 and 6T45 units, which GM built from 2008 through 2011, with some Gen 1 exceptions carried into later production. The listing title covers 2008-2013 for that reason, but 2012 and later Gen 2 units use a different friction count, with five 4-5-6 plates instead of four, and need a different module. Before you order, read the eighth digit on the TEHCM: 1, 2 or 3 is Gen 1 and fits this kit; B, C or D is Gen 2 and does not. Count the 4-5-6 frictions in your old pack as a second check. For 2015 and later units, see our Gen 3 6T40 clutch module. Send us the year and VIN if you want us to confirm it, or, for a Gen 1 6T45, see the 6T45 clutch module for 2008-2013.
Soak all fourteen frictions in Dexron VI for 30 minutes or more. Inspect the steels and replace any that are blued, glazed or out of flat. On a Gen 1 unit, never reuse the original 3-5-R wave plate; install an updated plate and inspect the drum splines for notching from a broken one. If the drum is damaged, our 6T45 clutch drum for 2008-up units is listed for these early transmissions. Replace the bonded pistons, set clearances, and air-check every clutch. Many builders also address the Gen 1 valve body at the same time with a 6T40 shift kit for 2007-2012. Refill with Dexron VI, level hot at the check plug, then clear adapts and relearn.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.


Only if the transmission is a Gen 1 unit. Most 2012 and later units are Gen 2. Check the eighth digit on the TEHCM label: 1, 2 or 3 is Gen 1 and fits.
Raybestos lists fourteen: four 1-2-3-4 and 2-6, four 4-5-6, three 3-5-R external spline, and three Low/Reverse plates.
On a Gen 1 6T40, yes. The original 3-5-R wave plate is a known failure point, so install an updated plate and check the drum splines.
Yes. Raybestos lists RHT96-246 for both the Gen 1 6T40 and 6T45.
Dexron VI. Set the level hot at the check plug, clear the TCM adapts, and drive through repeated shifts so the transmission relearns the new clutches.
