Full overhaul kit for 1997-2003 GM 4L60E with gaskets, seals, filter, band, bushings, bonded pistons and steels to rebuild the unit in one order.
A 1997-2003 Silverado 1500, Sierra 1500, Tahoe, Yukon, Suburban or S-10 that has lost 3rd and 4th, flares between gears, or comes back from the pan drop with black fluid and a fuzzy magnet is usually past the point of a reseal. This Remco kit is for that truck. It packs eight components into one order: the gasket and seal set, pan filter, 2-4 band, bushing kit, piston kit and steel plates, so a 1997-2003 4L60E can be torn down to the case and rebuilt without a second parts run halfway through.
The 4L60E shifts by filling clutch pistons and the 2-4 servo with line pressure from the valve body. Four things wear in that chain: the piston seals that hold the pressure, the steels that soak up the heat, the band that holds the reaction sun shell in 2nd and 4th, and the bushings that keep the drums and shafts running true so the sealing rings can do their job. A basic overhaul kit covers only the paper and rubber. This one adds the band, every bushing, new pistons and new steels. That matters on a high-mileage unit, because a heat-checked steel or a piston whose lip has taken a set will slip a brand-new friction pack, and a worn pump or stator bushing bleeds pressure out of the circuits you just resealed.
Rule out the cheap fixes first. Converter clutch slip with P0741 often comes from valve body bore wear, and harsh or soft shifts with P0748 point to the pressure control solenoid, not the clutches. Our 4L60E common problems guide walks through separating them. If the codes are clean, the fluid is burnt and the slip follows load and heat, the unit needs to come out. A stripped sun shell also kills 3rd and 4th, so check its splines when you tear down; that part is not in this kit.
This kit is listed for 1997-2003 GM 4L60E units, with the internal parts also named for the 4L65E and 4L70E that share the case and clutch layout. The gasket and seal set is the 1997-2003 pattern, and the listing notes that 2004-up units take different sealing and pan parts. If your transmission was built in 2004 or later, compare the 2004-up overhaul kit with steels and pistons instead. The truck's model year is not the final word: read the ID tag on the case, count the clutches in your 3-4 pack on teardown, and send us your year and VIN if you want us to check. Hard parts for the same unit are in the 4L60E collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
A 2002 half-ton with the 4L60E falls inside the 1997-2003 range this kit is listed for. Confirm with the ID tag on the transmission case, and send us the year and VIN if you want a second check before ordering.
A basic overhaul kit has gaskets, seals and usually frictions. This one also includes the 2-4 band, a bushing kit, a piston kit and steel plates, eight components in total, so worn pistons, steels and bushings are replaced along with the rubber.
No. The gasket, seal and pan parts in this kit are the 1997-2003 pattern. Later units take different sealing parts, so use a 2004-up kit for those transmissions.
Inspect the sun shell, input drum, forward sprag and pump while the unit is apart, since none of those hard parts are included. Many builders also add a shift kit to firm up apply rates on a towing truck.
Fill with Dexron VI ATF, soak the new frictions in the same fluid before assembly, and check the level hot at idle in Park after a test drive.
