4L60E Banner Rebuild Kit 1992-2003, new and ready to install. Fits the 4L60E. Ships fast from the USA.
Owners shopping for this kit usually have a first-generation 4L60E that is wearing out in one of three ways: the shifts flare and the engine revs between gears, the truck sits for a second in Drive before it moves, or the fluid has turned dark and smells cooked. That covers a lot of vehicles, from early C/K and GMT800 Silverado and Sierra 1500 pickups to Tahoe, Yukon, Suburban, S10, Sonoma, Blazer and V8 Camaro. This is a new Raybestos banner rebuild kit listed for 1992 through 2003 units, with frictions, overhaul gaskets and seals and a filter for one complete soft-parts job.
Every gear in a 4L60E is a combination of applied clutch packs, the 2-4 band and the one-way clutches working on two planetary sets. The valve body routes line pressure to a piston for each clutch, the piston clamps the frictions against the steels, and the gear is held. Two things wear in that chain: the friction lining loses its grip after years of heat, and the piston and lip seals harden until pressure bleeds off before the pack is fully applied. Either one feels like slip. The banner kit addresses both by replacing the friction plates and the full set of seals and gaskets, and the new filter keeps old debris away from the fresh clutches. It is a soft-parts kit, so drums, steels, shells, gears and bushings are reused or bought separately depending on what you find.
Drop the pan and look before you commit to a full overhaul. Fine gray paste is normal wear; flakes of lining and brass-colored debris mean clutches and bushings are going. If the main complaint is converter slip or a P1870 or P0741 code, Sonnax identifies TCC regulator valve bore wear as a primary cause, and the TCC regulator and isolator valve kit 77754-04K addresses that bore during the rebuild. Harsh or soft shifts with P0748 point to the pressure control solenoid instead, and our 4L60E shift solenoid guide explains how to test the solenoids. Slip in several gears with burnt fluid confirms the clutch packs are the problem.
The kit is listed for 4L60E units from 1992 to 2003, which is the whole first generation before GM's 2004 changes. Production started for the 1993 model year, so 1992 covers only the earliest units. The span includes two internal changes buyers should know about: the move from non-PWM to PWM converter clutch control in the mid-1990s, and a 2003 change to the internal harness and solenoid connectors, which is why our solenoid kits are sold in 1993-2002 and 2003-up versions. Gaskets that touch the valve body and separator plate must match your unit, so compare each one to the original before installation. Some 2001-2003 V8 trucks left the factory with the heavier 4L65E instead, so read the ID tag on the case first. If anything does not match, send us the year and VIN. The 4L60E collection lists every related part, and the 1992-2000 banner kit is an alternative for older units.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed through 2003. The 2003 4L60E uses a different internal harness and solenoid connector than earlier years, which does not change the frictions but can change gaskets. Check that the transmission is a 4L60E and not a 4L65E, and send us the year and VIN if you want a second check.
On a 4L60E the most common reason is a burned 3-4 clutch pack. A stripped sun shell gives a similar no-3rd/4th complaint, so inspect the shell on teardown. This kit fixes the clutch side; the shell is a separate part.
Yes, if they are flat and show no blue heat marks or scoring. Measure clutch pack clearance with the steels you will actually install, and replace any that are warped.
At minimum, any bushings that are worn, plus any hard part that fails inspection. Common add-ons are a sun shell, an input drum, extra 3-4 frictions for towing, and a TCC regulator valve kit if the truck had converter slip codes.
Dexron VI ATF. It supersedes the earlier Dexron fluids these units originally used. Check the level hot at idle in Park after the first drive.
