4L60E Transmission Master Rebuild Kit for 2004-Up Silverado

A master rebuild kit for the 2004-and-later GM 4L60E, also listed for the 4L65E, 4L70E and 4L75E. It carries the friction plates and steel plates for the clutch packs, the gasket set, seals and O-rings needed to put a torn-down unit back together. Package weight is about 12.3 lb, which tells you the steels are in the box, not just a soft-parts overhaul.

Listed coverage includes 2004-up Silverado 1500 and Express along with GMC, Cadillac and Hummer applications using the late-style 4L60E family. The 2004-up valve body gaskets differ from the early units, so verify the year of the transmission you are rebuilding.

This is the kit for a unit that came in with no 3rd and 4th, a slipping forward clutch, or burnt fluid and material in the pan. Soak the frictions in ATF before assembly, lube every seal, measure clutch clearances as each drum is built, and air check each circuit before the valve body goes back on. Inspect the sun shell, reaction shell and drums while it is apart; hard parts are not included.
