4L60E Clutch Module 2004, new and ready to install. Fits the 4L60E. Ships fast from the USA.
A 2004 GM truck or SUV with the 4L60E that flares between gears, has lost 3rd and 4th, or smells burnt at the dipstick usually needs a full set of clutches, and the gaskets and seals to go with them. This new 2004 clutch module, as pictured, pairs a Raybestos Powertrain RCP96-087 clutch pack with an overhaul set of gaskets, piston seals, sealing rings and front and rear seals. For 2004 that means Silverado and Sierra 1500, Tahoe, Yukon and Suburban, the final-year S10 and Sonoma, the Blazer, and the last 4L60E C5 Corvettes. It carries a 1-year warranty.
Raybestos catalogs RCP96-087 as a GM 4L60 and 4L60E clutch pack module with 24 frictions: 2 overrun, 5 low-reverse, 4 reverse input (second design, 1987 and later), 5 forward, and 6 high energy hardened-core 3-4 plates. All except the 3-4 plates are OE replacement material, and the pack is made in the USA. The photo also shows separator plate and pan gaskets, piston and case seals, sealing rings, front and rear seals and a check ball set. Steels, bands and bushings are not shown, so measure your old steels and plan on those separately if they are blued or scored.
Five clutches and one band share the work in this transmission. The forward clutch drives every forward gear, the 3-4 clutch applies on the 2-3 shift and stays on through overdrive, the reverse input and low-reverse clutches handle Reverse and manual Low, and the overrun clutch adds engine braking in the manual ranges. The 3-4 pack is the one that usually fails first, and the six high energy plates in this kit are aimed squarely at it. Sonnax blames most burnt 3-4 clutches on low line pressure and oil leaking out of the 3rd-gear circuit, so the new seals in this kit matter as much as the frictions.
Scan for codes first. On 2004 trucks a worn pressure control solenoid (P0748) or a TCC slip code (P0741) can cause soft shifts and cook new clutches, so fix those at the same time. Pull the pan and read the debris: fine friction material means clutches; chunks of steel mean hard parts. A stripped sun shell also leaves a truck with no 3rd or 4th, which our 3-4 clutch pack diagnosis guide helps you separate, and the overrun clutch guide covers the engine-braking complaints.
Listed for the 2004 4L60E. The six-plate 3-4 stack suits the V8 trucks; 4.3 V6 S10, Sonoma and Blazer units may use a five-plate stack, so set the pack to your housing and confirm clearance. Separator plate gaskets changed over the years, so match each gasket to your plate before you discard the old ones, and send us your year and VIN if you want it checked. More parts are in the 4L60E collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
The photo shows the Raybestos RCP96-087 frictions with an overhaul gasket and seal set. Steel plates are not shown, so measure your originals for flatness and heat marks and replace any that are blued or scored.
Yes, it is listed for 2004 4L60E units, which covers those trucks. Confirm the 3-4 stack and separator plate gaskets against your teardown, or send us your year and VIN before ordering.
Most repeat 3-4 failures come from low line pressure or oil leaking out of the 3rd-gear circuit, not from the frictions themselves. Replace the sealing rings and piston seals, check the pump and pressure control solenoid, and keep the load release springs in.
Soak the new frictions in Dexron VI for at least 30 minutes, then fill with Dexron VI and set the level hot in Park.
Reset the transmission adaptive values with a scan tool after the rebuild, then drive through light-throttle upshifts so the computer can learn the new clutches. Old adapts written for worn plates can make the first shifts harsh.
