4L60E Master Rebuild Kit 2004-2013, new and ready to install. Fits the 4L60E. Ships fast from the USA.
If your 2004-2013 Silverado 1500, Sierra 1500, Tahoe, Suburban or Yukon is flaring between gears, smells burnt on the dipstick, or has lost third and fourth altogether, the 4L60E behind the engine is usually due for a complete overhaul rather than one more patch. This master rebuild kit is built for the later 4L60E years, 2004 through 2013, and is meant to put fresh frictions, steels, seals and gaskets through the whole unit in a single teardown, so you are not opening the case twice.
The 4L60E is a four-speed rear-drive electronic automatic. Its gears are made by applying clutch packs and a 2-4 band in combinations commanded by the shift solenoids, with line pressure set by the pressure control (EPC) solenoid. Every one of those clutches is sealed by rubber or Teflon rings and lip seals. When frictions glaze and seals harden, apply pressure leaks off before the pack clamps, the pack slips, heat builds, and the cycle speeds up. A master kit renews the wear items in all of those circuits at once, which is the only way the new frictions get the full apply pressure they were designed around.
Codes alone do not tell you the hard parts are bad. P0741 can come from valve body bore wear, and P0748 is an electrical fault in the EPC circuit, so check those first because a rebuild kit will not fix either one. Drop the pan and look at what is in it: fine gray paste is normal, but black friction flakes or bronze and steel chips mean clutches and bushings are gone. Our 4L60E common problems guide walks through which complaints are internal and which are solenoid or valve body faults you can fix with the transmission in the truck.
This listing is for the 4L60E built from 2004 through 2013, the later production years used in GM full-size trucks and SUVs. That range is not one identical unit. In March 2007 GM revised the reaction carrier, its bearing and the output shaft, and those parts have to be kept together as a set during the rebuild. Late units also differ in pump-to-case sealing from the early ones. Before ordering, compare the old seals and gaskets to the kit, or send us your year and VIN and we will confirm it.

Since the valve body is off anyway, this is the time to address shift calibration and solenoids. Many builders add a TransGo Gear Command HD2 shift kit to firm up apply and protect the new 3-4 pack. The product specs list GM as the brand with a 1-year warranty. Ships from the USA.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2004-2013 4L60E units, which covers both. The reaction carrier, bearing and output shaft changed in March 2007, so keep your original gear train parts together and send your VIN if you want fitment confirmed.
Not by itself. P0741 on a 4L60E often comes from valve body bore wear, especially the TCC regulator bore. Rebuild or vacuum-test the valve body during the overhaul.
Dexron VI ATF. Soak the new frictions in it before assembly, prime the pump, then check level hot with the engine running.
Bushings, any worn drums or a damaged sun shell, the solenoids if they are original, and consider a shift kit. Have the torque converter serviced or replaced so debris from the old unit does not return.
Clearing adaptive values with a scan tool after the rebuild is good practice so the controller does not keep compensating for the worn clutches that came out.
