4L65E Banner Rebuild Kit 1992-2003, new and ready to install. Fits the 4L65E. Ships fast from the USA.
This kit is for the owner or shop tearing down an early 4L65E from a 2001-2003 Chevrolet or GMC truck: the Silverado and Sierra 2500 HD, Tahoe, Yukon, Suburban and Avalanche that now slips, shifts soft, slides into 4th or leaks from more than one seal. The photo shows the full soft-parts spread laid out: a cork pan gasket, valve body and separator plate gaskets, a pump-to-case gasket, three lip seals, a bag of sealing rings and O-rings, three stacks of friction plates for the different clutch packs, and a printed instruction sheet on fitting the sealing rings.
An early 4L65E is a beefed-up 4L60E rated by GM Performance at 430 lb-ft, built to sit behind the 6.0L and the higher-output 5.3L. Fluid from the pump is routed through the case and the stator shaft, across sealing rings, and into the clutch drums, where lip seals on each piston turn that pressure into clamping force. Once the rings wear grooves and the lip seals take a set, apply pressure leaks off before it reaches the clutch, the clutch slips, and the slip makes heat that cooks the friction plates. A banner kit replaces the parts in that chain that wear out: the rings, seals and gaskets that hold pressure, and the frictions that do the gripping.
Pull the pan first. Fine gray paste is normal; flakes of friction lining or brass means the unit is coming apart and a rebuild is the right call. If the fluid is clean and the problem is a single harsh or missed shift, an electrical fault is more likely, so scan for codes before you remove anything. Our 4L65E Tahoe common problems guide covers the failures that show up on the full-size SUVs, and 4L65E rebuild cost explains which hard parts usually turn a kit job into a bigger bill.
The listing covers 1992-2003. The 4L65E itself only exists from the early 2000s, so on a true 4L65E this kit is for the 2001, 2002 and 2003 model years. The earlier dates come from the 4L60E-family range the kit is cataloged under; the seals and frictions are shared across those units, but gaskets and plates changed during the run. Hold each gasket against its mating part and confirm every hole matches before you install it. A 2004 or later unit needs a later-design kit. If you are unsure, give us the year and VIN. The full parts list for this transmission is on the 4L65E collection page, and if you would rather have the Raybestos friction version for the same early trucks, see the 1992-03 banner kit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
On a true 4L65E it covers the 2001-2003 model years used in full-size Chevrolet and GMC trucks and SUVs. The earlier years on the label are 4L60E-family applications. Confirm your gaskets against the old parts, or send us the year and VIN.
No. A banner kit includes the gaskets, seals, sealing rings and friction plates. Buy steels if the old ones are heat-marked or warped, and bushings if any are worn.
The 3-4 clutch is the common failure on this unit, but the cause is often lost apply pressure from a worn pump, pressure regulator or input housing sealing rings. Fix the pressure loss during the rebuild or the new clutches will slip as well.
Use DEXRON-VI. GM lists 11.2 quarts dry for the 4L65E, but a refill after a rebuild depends on the converter and cooler, so fill, run the engine and check the level hot.
Both cover the same early trucks. This one is the GM-branded kit shown with three friction sets and an extra hardware bag; the 1992-03 listing is built around a Raybestos friction module. Pick the one that matches the parts you want to run.
