4L65E Banner Rebuild Kit 2004-2014, new and ready to install. Fits the 4L65E. Ships fast from the USA.
A late-model 4L65E that slips when it shifts into 4th, flares between gears on a hill, or drips from the pan and front seal is a rebuild candidate, and this kit is aimed at the 2004-and-newer units out of 5.3L and 6.0L Silverado, Sierra, Tahoe, Yukon, Suburban and Avalanche trucks. The photo shows a boxed Raybestos clutch pack with four sets of frictions, plus the gasket set, cork pan gasket, red lip seals, a large spread of O-rings and sealing rings, checkballs, springs and small plastic pieces for the valve body.
The 2004-on 4L65E keeps the familiar 4L60E-family gear train: overrun, forward, 3-4 and reverse input clutches, a low-reverse pack and the 2-4 band, with apply oil fed through sealing rings on the turbine shaft and stator support. GM rates the 4L65E at 430 lb-ft, but the clutch packs only hold that load as long as the frictions are fresh and the seals are tight. A banner kit restores both. The frictions bring back holding capacity, and the new rings, lip seals and O-rings stop the internal leaks that let pressure bleed away during a shift. The small valve body pieces in the box let you renew the parts that are easy to lose or crack during teardown.
On these trucks, electrical faults can feel like worn clutches. A failing shift or pressure control solenoid causes harsh, late or missed shifts with clean fluid, and our 4L65E shift solenoid symptoms guide shows how to separate the two. A whine that rises with engine speed points to the pump; the 4L65E pump failure guide covers that. GM's PIP5340A also notes that P0894 or P1870 and a harsh 1-2 shift can follow a converter or transmission replacement on these units, so recent work plus a code is not proof that the clutches are gone. Burnt fluid with lining in the pan is.
The listing covers 2004-2014. This kit is for the later design and is not the right kit for a 2001-2003 4L65E. In the full-size trucks the 4L65E was phased out around the 2007-2008 redesign, so the later years on the label come from the shared 4L60E-family case this kit also fits. Within the range, Sonnax notes GM moved to a thicker reaction carrier bearing in March 2007, which matters when you order hard parts. Match every gasket against the part it seals before installing, and send us the year and VIN if you want us to check. Every part for this unit is on the 4L65E collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. This kit is for 2004 and newer units. The 2001-2003 trucks use an earlier-design kit, and the gaskets and plates are not interchangeable across that split.
The photo shows a Raybestos clutch pack, gasket set with cork pan gasket, lip seals, O-rings, sealing rings, checkballs, springs and small valve body pieces. Steels and bushings are not included in a banner kit.
Not necessarily. GM PIP5340A describes P0894 or P1870 and a harsh 1-2 shift after converter or transmission replacement on these trucks. Check pressure, solenoids and the pan before deciding on a rebuild.
DEXRON-VI ATF. After the rebuild, flush the cooler, fill, run the engine, and check the level with the fluid hot.
If the truck had harsh, late or erratic shifts, yes. The valve body is already off, and replacing aged shift and pressure control solenoids then is much cheaper than pulling the pan again later.
