4L60E Master Rebuild Kit 1993-2003, new and ready to install. Fits the 4L60E. Ships fast from the USA.
When a 1993-2003 GM 4L60E has high miles, burnt fluid and slips in more than one gear, chasing one clutch pack at a time rarely pays off. This new master rebuild kit is meant for the full overhaul: it renews the frictions, steels, seals and gaskets throughout the unit so the whole transmission comes back on the same clock. Buyers searching for it usually drive a pre-2004 Silverado or Sierra 1500, Tahoe, Suburban, Yukon, S10, Sonoma, Blazer, Camaro or Corvette.
Every gear in the 4L60E comes from a clutch pack or band applying at the right moment. The overrun, forward, 3-4 and reverse input clutches each depend on friction plates biting against steels, and on piston seals holding the oil pressure that clamps them. After a lot of heat cycles, the frictions glaze, the steels discolor, and the seals harden and leak. A master kit addresses all of them at once, so you are not reassembling a fresh 3-4 pack next to a forward clutch that is one tow away from failing. Gaskets and seals throughout the case mean the rebuilt unit should stay dry.
Make sure the problem is clutches and seals, not hydraulics. Worn valve body bores can cause slip codes, harsh engagement and missing gears that look like clutch failure, and Sonnax's vacuum test guide maps specific bores to specific symptoms. Run through our 4L60E valve body rebuild walkthrough before you condemn the clutch packs, and use the overrun clutch guide if the complaint is lost engine braking. If the pan is full of lining and metal, the overhaul is the right call.
This kit is listed for the 4L60E from 1993 through 2003. The listing does not itemize a 2-4 band, bonded pistons or a filter, so plan to inspect those and order separately if needed. We also stock kits split by year, including the 1993-1996 master kit, and a 1993-2003 overhaul kit that lists its contents in detail. GM revised the 4L60E several times in this span, including separator plates and torque converter clutch apply parts, so compare gaskets and seals against what comes out of your case. For 2004 and newer trucks, a 2004-up kit is required. If you are unsure, send us your year and VIN. See all parts for this unit on our 4L60E collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for the GM 4L60E from 1993 through 2003. For a 2004 or newer truck, use a 2004-up kit.
The listing describes frictions, steels, seals and gaskets but does not itemize a filter, band or pistons. Plan to inspect those during teardown and order them separately if needed.
Lay the old plate next to each gasket and use the one whose holes line up exactly. GM changed the plate over these years, so the hole pattern matters.
With the valve body out, it is the cheapest time to do it. Worn solenoids cause shift and converter clutch complaints that a clutch rebuild will not fix.
Dexron VI ATF. Soak the frictions in it before assembly and recheck the level hot after the first drive.
