Overhaul gaskets and seals, friction and steel clutch sets, a new 2-4 band and pan filter in one box for 1997-2003 GM 4L60E rebuilds.
If your 1997-2003 Silverado, Sierra, Tahoe, Yukon, Suburban, S10, Blazer, Astro or Safari has lost 3rd and 4th, flares on the 1-2 shift, or left a pan full of black fluid and clutch lining, the 4L60E is due for a teardown. This kit puts the wear parts for that job in one box: the overhaul gasket and seal set, a full friction clutch set, a steel clutch set, a new 2-4 band and a pan filter. It is the middle option in our 4L60E line, more complete than a seals-and-frictions kit, without paying for pistons or bushings you may not need.
The 4L60E builds its four gears by holding or driving parts of two planetary sets. Five clutch packs (forward, 3-4, overrun, reverse input and low-reverse) each stack frictions and steels that a piston squeezes together. The 2-4 band does a different job: when the servo applies, it wraps the reverse input drum to hold it for 2nd and 4th. On a tired unit all of these wear at once, and steels that have taken heat can slip brand new frictions, which is why this kit replaces both sides of every pack.
The filter is the part people forget. Once a clutch pack burns, the debris loads the old filter and keeps circulating to the pump and valve body. A rebuild with a reused filter feeds that contamination straight back into the fresh clutches. Having the filter in the same box means the unit goes back together clean.
Pull the pan first. Clean fluid with a light gray film on the magnet usually means normal wear, while clutch lining and flakes mean a pack has already let go and the unit needs to come out. Then road test with a scan tool: compare commanded gear against input and output speed. Slip only in 3rd and 4th points to the 3-4 pack; slip in 2nd and 4th points to the band and servo. Rule out the electrical side before you commit, since a sticking EPC solenoid or a TCC slip code such as P0741 can come from valve body bore wear rather than the clutches. If the fluid simply looks old and the unit still shifts well, a service may be all it needs; our 4L60E filter and pan service guide covers that option.
This kit is listed for the GM 4L60E built from 1997 to 2003. That range covers the 4.3L V6 and the 4.8L, 5.3L and 5.7L V8s in C/K and Silverado and Sierra 1500 pickups, Tahoe, Yukon, Suburban, S10, Sonoma, Blazer, Astro and Safari. The 4L60E changed many times across its life, so 1993-1996 units and the later 4L65E and 4L70E do not share every part. One change that matters for the filter: in 1998 GM added a deeper oil pan to the 4L60E in its full-size trucks and vans, with a longer dipstick and tube, so match the filter to the pan depth on your unit. Read the tag on the case, or send us the year and VIN and we will check it. Year-by-year part lists are in our 1997, 1998 and 1999 4L60E rebuild guides, and everything else for this transmission is on the 4L60E parts page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 1997-2003 units. GM changed parts across the 4L60E's life, so for a 1993-1996 or 2004-up unit check the year-specific kits or send us the year and VIN before ordering.
The overhaul gasket and seal kit (pan, valve body and pump gaskets, front and rear seals, piston seals, O-rings and sealing rings), a friction clutch set, a steel clutch set, a new 2-4 band and a pan filter.
No. Pistons and bushings are not listed in this kit. If your pistons have hardened lips or your pump bushing is worn, buy those separately or choose one of our kits that includes them.
Usually it is part of the fix, because a burned 3-4 clutch pack is the common cause. Also inspect the sun shell splines, since a stripped sun shell gives the same symptom and is a separate part.
Use DEXRON-VI ATF. It is the current GM fluid and replaces the DEXRON-III these 1997-2003 units originally used. Fill to the hot level on the dipstick.
GM added a deeper pan to the 4L60E in its full-size trucks and vans in 1998, so filter depth varies by vehicle. Check your pan depth or send us the year and VIN so we can confirm it matches.
