4L70E Banner Rebuild Kit 1992-2003, new and ready to install. Fits the 4L70E. Ships fast from the USA.
This banner kit is for the early generation of GM's 4L60E family, the transmission found in 1990s and early-2000s Chevrolet C/K and Silverado 1500 pickups, Tahoe, Suburban, S-10, Blazer, Astro, Express, Camaro and Corvette, and their GMC, Pontiac and Oldsmobile twins. If yours slips, takes a long time to grab Drive, or has a pan full of dark, burnt fluid, this is the soft-parts set for a standard rebuild: a full transmission overhaul kit of gaskets and seals plus a standard set of friction clutch plates, with BorgWarner frictions in most kits. It is catalogued for 4L60E, 4L65E and 4L70E units dated 1992 through 2003.
The 4L70E name did not exist in this period. Vehicles from these years left the factory with a 4L60E, and the heavy-duty 4L65E arrived behind larger V8s near the end of the window. The 4L70E came later as the final version of the same design, which is why kits for this family are listed under all three names. What matters for this kit is the era: 1992-2003 units seal the pump to the case with a round O-ring, not the wedge seal used from 2004 on. Our interchange guide explains the other year-to-year changes.
A banner kit sits between a basic gasket set and a master kit. It renews every friction plate and every piston seal, O-ring, sealing ring and gasket, which covers what wears out in a typical high-mileage unit. It does not include steels, bushings, a band or a filter, so those are judged at teardown and bought only if needed. For a truck where the hard parts are still good, that keeps the cost of the rebuild down without leaving any tired rubber behind.
Pull the pan and inspect the filter and magnet. Heavy clutch debris confirms the unit needs a rebuild. If engagement is slow but the pan is clean, our delayed engagement guide covers the pump, filter and pressure faults that cause the same feel. Low line pressure is the usual reason a 3-4 pack burns in the first place, so test pressure before you trust a new set of frictions.
Catalogued for 1992-2003 GM 4L60E-family units with the round pump O-ring. It is not for 2004-up wedge-seal cases. Pump size, converter size and case style changed several times inside this window, but those changes are in hard parts, not the soft parts this kit replaces. Read the ID tag on the case, or send us your year and VIN to confirm. See all our parts for this family on the 4L70E collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes, if it has the original 4L60E. This kit covers 1992-2003 units in the 4L60E family, which includes the 1999-2003 Silverado and Sierra 1500 with that transmission. Send your VIN if you are not sure what is installed.
A complete overhaul kit of gaskets, seals, O-rings and sealing rings plus a standard set of friction clutch plates, BorgWarner in most kits. Steels, bushings, the band and the filter are not included.
No. From 2004 GM changed to a wedge-type pump-to-case seal that does not interchange with the round O-ring in this kit. Late units need a 2004-up kit.
Steels if yours are heat-marked, bushings, a filter, and often a shift kit. Inspect the pump and input drum, since a worn pump or leaking drum will burn new frictions.
DEXRON-VI. It replaces DEXRON-III in GM's service fill and is backward compatible with these earlier units. Soak the new frictions in it before assembly.
