Full 4L60E overhaul in one box for 1997-2003 GM trucks and SUVs: frictions, steels, band, gasket and seal set, bushings, washers and filter.
A 1997-2003 Silverado, Sierra, Tahoe, Suburban, Blazer, S10, Trailblazer, Envoy, Escalade, Camaro or Firebird that slips into 3rd, flares on the 2-3 shift, has lost 4th gear or leaves a dark, burnt-smelling film on the dipstick is usually telling you the 4L60E needs a full overhaul, not another fluid change. This master overhaul kit puts every soft part and wear part for that job in one box: a complete friction set, hardened steel plates, a new 2-4 band, the overhaul gasket and seal set with sealing rings and O-rings, bushings, thrust washers and a pan filter.
The 4L60E shifts by applying five multi-plate clutch packs (overrun, forward, 3-4, reverse input and low/reverse) plus the 2-4 band, which wraps the reverse input drum to hold it for 2nd and 4th. Every one of those apply devices depends on two things: friction material with grip left in it, and seals that hold apply pressure without leaking. When a unit has been slipping, both are worn at once. A gasket-and-seal kit alone leaves the burnt frictions in place, and new frictions alone get stacked against steels that may be heat-blued or no longer flat. Because this kit carries frictions, steels, band and seals together, the rebuild starts with fresh surfaces and fresh sealing everywhere the transmission makes or holds pressure. The bushings and thrust washers cover the spots where worn clearances let fluid bleed off past the sealing rings and drums.
Pull the pan first. Fine gray paste is normal; flakes of friction material, chunks of band lining or brass and steel chips mean the unit is coming apart inside and an overhaul is the right call. Scan for codes too. P0741 on these years usually points to torque converter clutch apply or valve body wear rather than the clutch packs, and P0748 points to the pressure control solenoid, so fix those causes or the new frictions will burn just as fast. If there is no 3rd or 4th at all, check the sun shell splines during teardown, because a stripped sun shell gives the same symptom and is not in a soft-parts kit. Our 1997 4L60E rebuild parts list lays out every part that fits the first year of this range, with the hard parts to inspect while the unit is apart.
This kit is listed for the 1997-2003 4L60E behind the 4.3L V6 and the 4.8L, 5.3L, 5.7L and 6.0L V8s: Chevrolet Silverado 1500, Tahoe, Suburban, Blazer, S10 and Trailblazer; GMC Sierra 1500, Jimmy, Safari, Savana, Envoy and Sonoma; Cadillac Escalade 1999-2003; and the Camaro and Firebird. The year split matters. Overhaul kits are cataloged 1997-2003 and 2004-up because GM changed piston and seal design for 2004, and the unit itself changed inside this range: a bolt-on bellhousing was phased in for most applications in 1998, and Gen III V8 trucks picked up a 300 mm converter, pump and input shaft that same year. Read the ID tag on the case and match it to your year before ordering. If you are not sure, send us your year and VIN and we will check it. Year-specific parts lists for 1998, 1999 and 2000 are on our blog, and every 4L60E part we carry is on the 4L60E collection page. For a 2004-up unit, use the 2004-up overhaul kit instead.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is listed for 1997-2003 units. Overhaul kits are split at 2004 because GM changed piston and seal design that year, so a 2004-up truck needs a 2004-up kit.
No. It covers frictions, steels, the 2-4 band, the gasket and seal set, sealing rings, O-rings, bushings, thrust washers and a filter. Pistons, hard parts and the converter are separate.
Usually it fixes a burned 3-4 pack, but no 3rd or 4th can also be a stripped sun shell, which is a hard part. Check it during teardown before reassembly.
Dexron VI ATF. Prime the pump on install, then check the fluid level hot with the engine running.
Read the ID tag on the transmission case and match it to the vehicle year. If you are unsure, send us your year and VIN and we will confirm fitment.
