Full overhaul set for the GM 4L60E: frictions, steels, band, filter, bushings and every seal and gasket needed for a 1997-2003 rebuild.
If your 1997-2003 Silverado 1500, Tahoe, Suburban 1500, Blazer, S10, Astro, Express 1500, Trailblazer, Camaro or Escalade has started slipping in 3rd, flaring on the 2-3 shift or falling out of overdrive once it warms up, the 4L60E has usually worn its clutches and its seals together. This master overhaul kit is built for that job. It includes the full set of friction plates and the matching steel plates, the 2-4 band, a new filter, the overhaul gasket set, metal-clad and lip seals, O-rings, Teflon sealing rings, a pump bushing and an extension housing bushing.
A plain overhaul kit is gaskets and seals only. A master kit adds the parts that actually transmit torque. In the 4L60E that means five clutch packs (overrun, forward, 3-4, reverse input and low/reverse) plus the 2-4 band that holds the reverse input drum for 2nd and 4th. Raybestos lists the stock overrun pack at just two frictions, while the 3-4 pack carries far more load and is the one that usually burns first. When a unit has slipped long enough to char the frictions, the steels next to them are often heat-blued or warped. Including new steels means you are not stacking fresh frictions against plates that may not be flat, which is a common reason a cheap rebuild slips again within a few thousand miles. The two bushings in the box cover the pump and tailshaft wear points that leak or let the shafts wobble.
Rule out the cheap causes first. Low line pressure, a cross-leaking 2-4 servo, or a worn valve body bore will burn a new 3-4 pack just as fast as the old one. Code P0741 on these years usually traces to converter clutch apply rather than the clutch packs, and P0748 points to the pressure control solenoid. Our 3-4 clutch apply and AFL valve guide walks through the pressure checks, and the 2-4 band and servo guide covers the servo pin and seal problems that take out the band. For a wider symptom list, see our 4L60E common problems guide.
The listing covers the 4L60E built from 1997 through 2003 in the Silverado 1500, Tahoe, Suburban 1500, Blazer, S10, Astro, Express 1500, Trailblazer, the 1997-2002 Camaro, and the 1999-2003 Escalade including the EXT and ESV. Check that your unit is a 4L60E and not a 4L65E. The 4L65E uses five-pinion planets and a different 3-4 clutch count, so this kit is not a match for it. Read the case ID tag or the glovebox RPO list (M30 is the 4L60E), and send us your year and VIN if you want us to verify. The rest of our hard parts for these years are on the 4L60E parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It includes both the friction plates and the steel clutch plates, along with the band, filter, gaskets, seals, sealing rings and the pump and extension housing bushings.
No. The 4L65E uses five-pinion planets and a different 3-4 clutch count. This kit is for the 4L60E built from 1997 to 2003.
Inspect the sun shell, sprags, drums and pump for wear. Rounded sun shell splines, a cracked drum or a scored pump will undo the rebuild, so replace those hard parts if they are damaged.
Often, yes, but low line pressure or a leak in the 3rd gear circuit is usually what burns that pack. Check pressure and the servo before rebuilding, or the new clutches can fail the same way.
Soak the frictions in clean ATF for at least 15 minutes. Fill the rebuilt unit with Dexron VI ATF and check the level hot at idle in Park.
