High energy frictions, steel plates, 2-4 band, filter, pan gasket and bagged seal sets for rebuilding a 1997-2003 GM 4L60E automatic transmission.
A 4L60E that cooked itself pulling a trailer or climbing grades rarely fails in just the frictions. Heat warps and glazes the steel plates too, and reusing them is one of the most common reasons a fresh rebuild slips again within months. This super rebuild kit for the 1997-2003 4L60E includes the steels, so you replace both sides of every clutch pack. It is a fit for Silverado and Sierra 1500, Tahoe, Suburban, Yukon, S10, Blazer, Astro and Camaro owners whose transmission is slipping, flaring or running hot.
Each 4L60E clutch pack alternates lined friction plates with plain steel plates. When the piston applies, the frictions grip the steels and the steels carry heat away from the lining. After a hard slip the steels can turn blue, develop hot spots, or warp slightly, and a warped steel will not let a new friction seat flat across its face. The result is a pack that slips under load, overheats the new lining, and fails early. The high energy frictions in this kit are made to tolerate more heat than a basic paper lining, and pairing them with flat, clean steels gives them the full contact area they need. The new 2-4 band covers 2nd and 4th, which depend on the band wrapping the reverse input drum when the servo applies.
Check fluid color and smell, then drop the pan and look at the filter and magnet. Fine friction dust with some metal is normal wear; large flakes of lining or a coat of black sludge mean a pack has burned. A scan tool comparing input and output speed tells you which gears are slipping. Make sure an electrical problem is not causing the symptoms first, because a failed shift solenoid can give you a one-gear or no-upshift complaint that looks mechanical; the 4L60E shift solenoid guide covers how to test them. For the mechanical failures, the common problems guide lays out what each symptom usually means.
This kit is for the GM 4L60E built from 1997 through 2003, which sits behind the 1997-2003 Silverado and Sierra 1500, Tahoe, Suburban, Yukon, S10, Blazer, Astro, Camaro and other GM rear-wheel-drive trucks and cars of that era. Units from 1993-1996 and 2004-up use different parts and need their own kits. Because GM made running changes inside this window, read the ID tag on the case, compare old parts to new on the bench, or send us the year and VIN and we will confirm fitment. Browse all parts for this transmission on the 4L60E collection page.
Drums, shells, bushings and planets are not included. The 4L60E bench tools guide lists the gauges and spring compressors that make the job go smoothly.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
If the steels are flat, not blue and not glazed, they can sometimes be reused. On a unit that failed from heat, they are rarely in that condition. New steels remove a common cause of early slipping after a rebuild, which is why this kit includes them.
No. This kit is for the 1997-2003 4L60E. The 2004-up units use different parts and need a 2004-up kit, which we also carry.
They are friction plates with a lining designed to handle more heat than a basic paper friction. They help on trucks that tow or run hot, but they still need good line pressure and correct clearance to last.
Inspect and replace worn drum bushings, the sun shell if its splines are damaged, and the pump if it is scored. Service or replace the torque converter and flush or replace the cooler so old debris does not reach the new clutches.
Dexron VI ATF. Check the level hot after the first drive, since a freshly rebuilt unit can take more fluid once the converter and cooler fill.
