4L60E Banner Rebuild Kit 1993-2003, new and ready to install. Fits the 4L60E. Ships fast from the USA.
The 1993-2003 4L60E covers the first ten-plus years of GM's electronic four-speed, from the 1993 C/K pickups and Suburbans through the early GMT800 Silverado 1500 and Sierra 1500, plus Tahoe, Yukon, S10, Blazer, Sonoma, Camaro and Firebird. Nearly all of these trucks and cars now carry high mileage, and a tired one shows up as slipping on the upshifts, a slow bite into Reverse, or fluid that smells burnt. This new banner rebuild kit supplies the friction plates, overhaul gaskets and seals and the filter for one complete overhaul of a unit from that range.
A 4L60E gets each gear by applying a combination of clutch packs and the 2-4 band against its two planetary gear sets. Fluid pressure from the valve body pushes each clutch piston, and the piston seals are what keep that pressure in the drum. After twenty-plus years the rubber in those seals is hard, the paper lining on the frictions has glazed, and the filter is loaded. The banner kit replaces all three at once: new frictions so each pack can grip again, a complete set of seals and gaskets so apply pressure stays where it belongs, and a filter so debris from the old failure does not feed the new clutches. The hard parts in the box, including drums, steels and gears, are reused when they inspect clean.
Pull codes and check the fluid first. A P0741 on these years frequently comes from valve body bore wear, and our 4L60E valve body rebuild walkthrough shows how to identify it. If the complaint is a harsh or slurred 1-2 shift rather than slip, the accumulator may be the cause; a Sonnax pinless accumulator piston kit replaces a worn or damaged 1-2 accumulator piston while the pan is down. If you have true slip in several gears with burnt fluid, the overhaul is the fix.
This kit is listed for 1993-2003 4L60E transmissions. That is a long window, and GM made real changes inside it. According to Sonnax, the earliest units use non-PWM converter clutch apply parts while later units moved to a PWM TCC, and the valve body and separator plate changed along with them. In 2003, GM also changed the internal harness and solenoid connectors. Because the pattern changed, lay each new gasket over the old one and confirm every hole lines up before you install it. If you own a 2001-2003 truck with the 6.0 V8, read the tag, because many of those got the heavier 4L65E. If you know your exact year, the narrower 1993-1997 banner kit is another option. Send us your year and VIN if anything does not match, and browse the 4L60E collection for every related part.
If you find worn steels, a cracked drum or a tired band during teardown, the 1993-2003 master rebuild kit covers more of the job in one box. See the bench tools guide before you start.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for the full 1993-2003 range. Because GM changed the TCC apply parts and the 2003 harness, compare each gasket with the original before installing, and send us your year and VIN if you are unsure.
Possibly not. Many 6.0 trucks from that era use the heavier-duty 4L65E. Check the transmission identification tag on the case before ordering.
Use Dexron VI ATF. It is GM's current specification and is backward compatible with the Dexron III these units shipped with.
No. A banner kit covers frictions, seals, gaskets and a filter. Reuse steels and bushings only if they inspect well, or step up to the master kit.
If the delay comes from hardened piston seals or worn forward clutch frictions, yes. Confirm fluid level and check the forward sprag and pump before assuming the clutches are the only problem.
