Overhaul gaskets and seals, friction clutch plates, 2-4 front band, pump bushing and filter for rebuilding a 1998-2003 GM 4L60E transmission.
A 1998-2003 Silverado, Sierra, Tahoe, Yukon, Suburban, S10, Blazer, Astro or Camaro that flares on the 1-2 shift, slips out of 2nd or 4th, or leaks from the front of the bellhousing is a classic candidate for this kit. It is a Remco soft-parts rebuild built around the three items that most often bring a 4L60E back after a cheap overhaul: the friction plates, the 2-4 band and the front pump bushing. Everything that seals the unit comes in the same box, along with a new filter.
The 4L60E uses clutch packs for most of its ranges, but 2nd and 4th are held by a single band wrapped around the 3-4 clutch drum and squeezed by the 2-4 servo. That one band carries two of the four forward gears, so when it glazes or cracks the truck loses 2nd and 4th specifically while 1st, 3rd and Reverse still work. The pump bushing is the other quiet failure: it supports the converter hub, and when it wears the hub wobbles, the front seal starts leaking and the pump loses some of its ability to hold line pressure. This kit replaces both, renews the friction surfaces in the clutch packs, and supplies the overhaul set of valve body and spacer plate gaskets, cork pan gasket, front pump seal, rear extension seal, piston seals, O-rings and sealing rings.
Not every 4L60E shift complaint needs a teardown. A worn pressure control solenoid causes harsh or soft shifts and code P0748, and valve body bore wear can slip the converter clutch and set P0741 with the clutch packs still healthy. Scan for codes, watch commanded gear against actual gear on a scan tool, then drop the pan. Band lining and brass in the filter mean the unit is coming apart. Our 4L60E common problems guide walks each complaint back to its cause, and the 2-4 band and servo guide explains why a new band alone often fails again if the servo pin and bore are ignored.
This kit is listed for the 1998-2003 GM 4L60E only. GM changed pump and case details at both the 1998 and 2004 breaks, so a 1997 or a 2004 unit can need different seals and a different filter. Before ordering, read the transmission ID tag on the case, confirm the model year from the VIN, and compare your pump and pan against the parts in the kit. If you are not sure which side of a break your unit falls on, send us the year and VIN and we will check it. Earlier and later kits are on the 4L60E parts page.
The tools and checks that make this job go smoothly on the bench are covered in the 4L60E bench rebuild tools guide.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 1998-2003 only. GM changed pump and case details at the 1998 and 2004 breaks, so a 1997 or 2004-up unit should use the kit for its own years. Check the case ID tag and VIN year, or send us the year and VIN to confirm.
No. It includes the gasket and seal set, friction plates, a 2-4 band, a front pump bushing and a filter. If your steels are blued, warped or scored, choose a kit that includes steels instead of reusing them.
Those are two of the most common reasons a 4L60E comes back after a frictions-only rebuild. A worn band causes flare and lost 2nd and 4th gear, and a worn pump bushing lets the converter hub wobble, ruins the front seal and costs line pressure.
Use Dexron VI ATF. Soak the new frictions in the same fluid for at least 30 minutes before assembly.
Inspect the sun shell splines, the 2-4 servo bore and pin, and the steels. Many builders also replace the shift and pressure control solenoids and add a shift kit at this stage, since the valve body is already off.
