About this product

A 2008-2013 6T45 that slips when it gets hot, flares between gears on the highway, or leaves burnt fluid and lining dust in the pan is a transmission whose clutch frictions have given up. This is a Raybestos friction module, manufacturer part number RHT-246, made in the United States and listed for both the 6T40 and the 6T45 from 2008 through 2013. That span covers the early Gen 1 units and the Gen 2 update GM phased in during 2012, so it is the friction set a rebuilder reaches for when one of those first-generation GM six-speeds is on the bench.

What the clutch module does in a 6T45

The 6T45 has no bands. Every ratio comes from applying two of its five clutch packs at the same time: low and reverse, 1-2-3-4, 2-6, 3-5-reverse and 4-5-6. Each pack is a stack of lined friction plates splined to one member and steel plates splined to another, and a hydraulic piston clamps the stack to lock them together. The control module watches input and output speed and adjusts pressure to keep each apply smooth and fast. As the lining glazes or burns, the pack needs more pressure and more time to lock, the module runs out of adaptive range, and the driver starts to feel the slip. Because each clutch works in several gears, one worn pack can make a whole group of shifts feel wrong.

Symptoms that point at worn frictions

How to confirm it before you buy

Not every 6T45 shift complaint is a clutch problem. GM released a calibration for a harsh 2-3 shift on the 2011 Equinox, Terrain and Captiva 2.4L, and a sticking pressure control solenoid can drop gears and set slip codes on a unit with good frictions. Set the fluid level hot through the check plug first, read every stored code, and note exactly which gears slip. Our 6T40 and 6T45 shift solenoid guide walks through the control faults to eliminate, and the common problems and fixes guide covers the 3-5-reverse wave plate and piston failures that often travel with burnt frictions. If the pan is full of lining debris, the case is coming apart and this module belongs on the order.

Fitment: 2008-2013 6T45 and 6T40

RHT-246 is listed for 6T40 and 6T45 transmissions built from 2008 to 2013. GM's PI0604C notes that the Gen 2 update brought revised identification markings on several friction plate assemblies, and some 2012 models stayed on Gen 1 parts, so lay each old plate beside its replacement and match count, thickness and tooth pattern before it goes in. If your unit is a 2015 or later build, the 2015-up 6T45 clutch module is the correct set. Send us your year and VIN if you are unsure which design you have, and if you are rebuilding the lighter-duty sibling instead, the same years are covered by the 2008-2013 6T40 clutch module listing.

6T45 Clutch Module 2008-2013: common questions

Does this fit a 6T40 as well as a 6T45?

Yes. Raybestos RHT-246 is listed for both the 6T40 and the 6T45 from 2008 to 2013. Compare each plate against the one you remove before installing.

My 2012 Equinox is a Gen 2 unit. Will this work?

The module is listed through 2013, which includes the Gen 2 changeover. GM revised the identification markings on some Gen 2 friction plates, so match the old plates to the new ones, or send us your VIN and we will check it.

What should I replace along with the frictions?

Piston seals or bonded pistons, the filter and a full gasket set, plus any steels, drums or wave plates that show heat damage, worn splines or cracks.

Can a bad solenoid cause the same slipping?

Yes. A pressure control solenoid fault can cause missing gears and slip codes on a unit with good clutches. Check codes and solenoids before tearing down the transmission.

What fluid does the 6T45 take, and does it need a relearn?

DEXRON VI, with the level set hot at the check plug. After new frictions go in, clear the adaptive values and complete a relearn so the shift timing matches the new packs.
