Six-piece 4L60E rebuild kit for 1997-2003 units: high friction clutch pack, blue bonded pistons, Pro-Series band, deep pan filter and gasket set.
Not every tired 4L60E needs new steel plates. If you have the unit apart and the steels came out flat, clean and in spec, paying for a new set adds cost without adding life. This six-piece deluxe kit is built for that rebuild: it replaces the frictions, the pistons, the band, the pump bushing, the filter and every gasket and seal on a 1997-2003 4L60E, 4L65E or 4L70E, and leaves the steels to you.
The 4L60E holds and drives its two planetary gearsets with clutch packs and a 2-4 band. The frictions are the wear surface in each pack; the steels are the mating surface that also carries heat away. When a unit slips, the frictions wear first, but the piston behind them is often the real cause, because a hardened or cracked rubber bond lets apply pressure leak away. That is why this kit pairs the high friction clutch pack with a blue bonded piston kit. The 2.280 in wide Pro-Series flex band covers the 2-4 holding member, the babbitt pump bushing supports the converter hub, the deep pan filter catches break-in debris, and the overhaul set reseals the case, pump and drums.
This decision is made on the bench, not before teardown. Lay each steel on a flat surface and check it for warp, look for blue heat marks, hot spots and scoring, and measure thickness against the overhaul manual. Any steel that is coned, blued or scored gets replaced, because reusing it will cook the new frictions. If more than a few fail, the 4L60E super rebuild kit with steels is the better value. Shift feel complaints that do not come with burnt fluid may be hydraulic instead; the 1-2 accumulator and shift feel guide covers that side.
The listing covers GM 4L60E, 4L65E and 4L70E units in the 1997-2003 range. Check the unit code on the ID tag on the case to confirm which transmission you have, and confirm the year from the build date, since earlier and later cases differ in pistons and gaskets. The filter is the deep pan style, so a shallow pan needs a different filter. Compare the kit contents with your parts or send us the year and VIN before ordering. Other year ranges are in the 4L60E collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It is a less steels kit. It is meant for rebuilds where the original steels are flat, unscored and within thickness spec. If they are blued or warped, buy a kit that includes steels.

A high friction clutch pack, a blue bonded piston kit, a 2.280 in wide Pro-Series flex band, a deep pan filter, a babbitt pump bushing and an overhaul gasket and seal set.
A hardened or cracked piston bond leaks apply pressure, so a clutch can slip even with new frictions. Replacing the pistons along with the frictions is what keeps a rebuild from coming back.
Dexron VI ATF. Prime the pump and converter on install and check the level hot.
