Heavy duty overhaul kit with high energy friction clutches for rebuilding a 1997-2003 GM 4L60E, also fits later 4L60E and M30 units.
If your Silverado, Sierra, Tahoe, Yukon or Suburban tows a camper, hauls a bed full of weight, or has an engine making more than it did on the showroom floor, the stock friction material in its 4L60E is usually the first thing to quit. The typical story is a flare on the 2-3 or 3-4 shift, then no 4th at all, then a pan full of dark fluid and clutch lining. This heavy duty kit is meant for that rebuild: it is listed for every 1997-2003 4L60E plus the 2004-and-later 4L60E used in Chevrolet and GMC trucks, SUVs and vans, and it swaps the factory frictions for high energy clutches that tolerate heat better.
The 4L60E (GM RPO M30) is a four-speed rear-drive automatic that gets every gear from clutch packs and a single 2-4 band, all applied by line pressure that the valve body routes on command from the PCM. Each friction plate is a paper-based lining bonded to a steel core; when that lining gets hot enough it glazes, then chars, and the pack can no longer hold torque without slipping. Slipping makes more heat, and the cycle finishes the pack quickly. A high energy friction uses a lining built to absorb more heat per engagement before it breaks down, which is why it is the usual choice for a working truck. The kit also renews the seals, gaskets and rubber that keep apply pressure where it belongs, so the new frictions actually get full pressure behind them.
Check the fluid level and smell first, then drop the pan. A little fine gray paste on the magnet is normal wear; brown lining flakes and a filter packed with debris mean the clutches are gone and a reseal will not help. Scan for codes as well. A P0741 converter clutch code or a P0748 pressure control solenoid code points at the valve body or solenoid side, and those problems can cook a fresh set of frictions if they are not fixed during the rebuild. Our 4L60E common problems guide walks through which complaint points at which component.
This kit is listed for all 1997-2003 4L60E transmissions and the 2004-up 4L60E in Chevrolet and GMC applications, which covers the Silverado 1500, Sierra 1500, Tahoe, Yukon, Suburban, Express and Savana and similar M30 trucks and vans. Read the ID tag on the case before ordering: it must say 4L60E. A 4L65E or 4L70E looks almost the same from the outside but uses different drum components, and those units need their own kit. If you are not sure what is under your truck, send us the year and VIN and we will check it. You can compare other kits and hard parts on our 4L60E parts page.
The kit weighs about 9.5 lb boxed and carries a 6-month warranty.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2004-and-later 4L60E Chevrolet and GMC applications as well as 1997-2003 units, so a 2007 half-ton with a 4L60E tag is covered. Confirm the tag says 4L60E and not 4L65E or 4L70E, or send us the year and VIN to check.
High energy linings handle more heat per shift before they glaze or char. That matters on a truck that tows, hauls, or has more power than stock, because heat is what kills 4L60E clutch packs, especially the 3-4 pack.
If the cause is a burned 3-4 clutch pack, yes, as part of a full rebuild. If the sun shell splines have stripped, you also need a new sun shell, which is a hard part not covered by the frictions in this kit.
Inspect and budget for the sun shell, forward sprag, bushings and steels, and have the right tools for the clutch springs and Teflon rings. If you had P0741 or P0748 codes, address the valve body or pressure control solenoid too.
Use Dexron VI ATF. Pre-soak the frictions in the same fluid, then check the level hot at idle in Park after the first drive.
