4L60E Master Rebuild Kit 2004-2014, new and ready to install. Fits the 4L60E. Ships fast from the USA.
This kit covers the late-production 4L60E: the units GM built from 2004 until the four-speed was phased out of its last half-ton trucks and SUVs. If a 2004-or-newer Silverado 1500, Sierra 1500, Tahoe, Yukon or Suburban is flaring between gears, will only pull in 1st and 2nd, or leaves a pan full of black lining material, this new master rebuild kit puts fresh frictions, steels, seals and gaskets in the whole unit at one time.
The late 4L60E shifts the same way the early one did. Hydraulic pressure from the pump, metered by the valve body and the electronic pressure control solenoid, pushes pistons that clamp the overrun, forward, 3-4 and low/reverse clutches and applies the 2-4 band through its servo. Every one of those circuits relies on a piston seal holding pressure and a friction plate with lining left on it. Once one pack burns, its debris circulates through every other circuit, so an overhaul that renews only the failed pack usually comes back. A master kit resets all of the wear items in a single teardown.
Two common late-4L60E codes are not clutch failures. P0741 (converter clutch slip) is frequently a worn TCC regulator bore in the valve body, and P0748 points at the pressure control solenoid circuit. Run through the 4L60E common problems guide to separate hydraulic and electrical faults from mechanical ones, then pull the pan. Heavy lining debris plus missing gears means the clutches are finished and this kit is the right buy. If the fluid is clean and the problem is a code, look at the valve body first; a replacement 4L60E valve body costs far less than a teardown.
The listing covers 4L60E units from 2004 through 2014. Two running changes inside that window matter on the bench. From 2004 on, GM used a reluctor-style stator support, so the pump and input speed hardware differ from 1997-2003 units. In March 2007 GM revised the reaction carrier bearing, carrier and shaft together, and Transmission Digest warns that early and late pieces must be kept as a matched set. This kit replaces soft parts, not those hard parts, but it pays to know which version you are reassembling. Our model data shows the 4L60E in GM half-ton applications through 2013; if your vehicle is a late carryover or sits on a model-year boundary, check the transmission tag or send us your year and VIN before ordering. Every part we stock for this unit is on the 4L60E collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Late 4L60E units in GM half-ton trucks and SUVs such as the Silverado 1500, Sierra 1500, Tahoe, Yukon and Suburban. Confirm with the transmission tag or send us your year and VIN if you are near a model-year change.
The clutch and seal kit is the same listing, but GM changed the reaction carrier bearing, carrier and shaft in March 2007. Keep whichever version your unit has as a matched set when you reassemble it.
No. A master rebuild kit is the soft parts: frictions, steels, seals and gaskets. Inspect the sun shell, drums and pump during teardown and replace them separately if worn.
Usually not first. Converter clutch slip codes often come from a worn TCC regulator bore in the valve body. Test or replace the valve body before committing to a full overhaul.
Dexron VI ATF. Check the level with the engine running and the fluid at operating temperature, then clear the adaptive values so shifts relearn.
