Full 4L60E overhaul kit with frictions, steels, seals, gaskets and filter for 2004-2010 Silverado, Sierra, Tahoe, Yukon and Escalade rebuilds.
If your 2004-2010 Silverado 1500, Tahoe, Yukon or Sierra has started flaring between 3rd and 4th, slipping when it pulls off in drive, or the fluid on the dipstick smells cooked, the transmission is usually past the point of a fluid change. This master rebuild kit is built for that late generation of the GM 4L60E, and it also covers the 4L65E and 4L70E that share the same core hardware. Frictions, steels, the seal and sealing ring set, gaskets and a new pan filter come together in one box, so the case can be split once and closed once.
The 4L60E is a 4-speed rear-wheel-drive automatic that makes every gear by applying clutch packs and a band in different combinations. The forward clutch holds the truck in drive, the 3-4 clutch carries the load in 3rd and 4th, the overrun clutch gives engine braking in manual ranges, the reverse input clutch drives reverse, and the low-reverse pack holds in manual low and reverse. When any one of those packs burns, its debris circulates through the rest of the unit and the valve body. A master kit renews the friction material and steel plates in each pack and replaces every lip seal, piston seal and sealing ring that holds apply pressure, so you are not trusting a 15-year-old seal behind a new clutch pack.
Drop the pan and read the debris. A light gray film is normal wear. Flakes of friction lining, chunks of band material, or bright steel on the magnet mean the unit needs to come apart. Shift-quality complaints are not always clutches: a worn valve body can cause TCC slip and P0741, and pressure control solenoid wear can cause harsh or soft shifts and P0748. Our 4L60E common problems guide walks through separating those failures, and the valve body rebuild walkthrough explains how to tell if the valve body needs work while the unit is out.
Listed fitment includes 2004-2010 Chevrolet Silverado 1500 and Tahoe with the 4.3L, 4.8L, 5.3L, 6.0L and 6.2L engines, 2004-2007 GMC Sierra 1500 and Savana 1500, 2004-2010 GMC Yukon, 2004-2006 Cadillac Escalade, 2007-2008 Avalanche, 2004-2005 Corvette, and 2004-2010 Colorado and Canyon. Check that your unit is a 4L60E-family transmission (RPO M30, M32 or M70) before ordering. GM revised parts within this range, so lay your old gaskets over the new ones and match the hole pattern before assembly. If you are not sure, send us your year and VIN. Every part we carry for this unit is on the 4L60E parts page, and if your truck is 1997-2003 the 1997-2003 master rebuild kit is the correct box.
Hard parts are not included. Inspect the sun shell, input drum, reaction carrier and pump, and budget for them separately if they are worn. A holding fixture makes the teardown much easier, and the reverse input lip seal protector keeps the new seals from rolling during drum assembly. Our bench tools guide lists the rest of the tools you will need.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. 2004-2010 Silverado 1500 with the 4.3L, 4.8L, 5.3L, 6.0L and 6.2L engines are on the listed fitment. Confirm the transmission is a 4L60E family unit (RPO M30, M32 or M70) on the glovebox sticker, and send us your VIN if you want us to double check.
No. It covers the frictions, steels, seals, sealing rings, gaskets and filter. The sun shell, input drum, reaction carrier, pump and bushings are hard parts that need inspection during teardown and are bought separately if they are damaged.
Dexron VI ATF. Use it to soak the new frictions for at least 30 minutes before assembly and for the initial fill.
Usually, because a burnt 3-4 clutch pack is the most common cause. But if the 3-4 pack looks fine at teardown, check the sun shell. Stripped sun shell splines cause the same no 3rd or 4th symptom, and that part is not in this kit.
Yes. The kit is listed for the 4L60E, 4L65E and 4L70E, which share core hardware. Match the gaskets against your originals before assembly, since GM changed parts during the production run.
