4L60E Banner Rebuild Kit 2004, new and ready to install. Fits the 4L60E. Ships fast from the USA.
A 2004 Silverado, Sierra, Tahoe, Yukon or Suburban with a 4L60E has usually covered serious miles by now, and many of them spent those miles towing. When the transmission starts slipping on the upshifts, smells burnt on the dipstick, or takes a moment to engage Reverse, this new banner rebuild kit gives you the frictions, seals, gaskets and filter for an overhaul built around the 2004 model year.
Inside the 4L60E, clutch packs in the input housing and case do the work of selecting gears, with the 2-4 band holding 2nd and 4th. Every one of those packs depends on a piston seal holding pressure and on friction lining that has not glazed. Heat is what ruins both, and a 2004 truck that tows or idles in traffic sees plenty of it. A banner kit replaces the friction plates, the overhaul seal and gasket set and the filter in one purchase, so you are not chasing one tired seal after another. Steels, bushings and hard parts are reused if they inspect well.
Pull codes before you tear anything down. P0748 points to the pressure control solenoid, and P0741 converter clutch slip often traces to valve body wear rather than the clutches, which a banner kit will not fix. The 4L60E shift solenoid guide covers electrical testing, and the 1-2 accumulator and shift feel guide separates harsh or soft shifts from true slipping. Slipping under load with burnt fluid, though, is a clutch job.
This kit is listed for the 2004 model year, and that year has its own parts profile. Sonnax lists the late-style pressure control solenoid from 2003 on and a reluctor-style stator support shaft from 2004 on, where earlier units used a non-reluctor shaft. Its stator compatibility article also points out that several input shaft, stator and pump cover combinations exist, so a 2004 unit that has been apart before may not match the book. Transmission Digest documents a March 2007 GM change to a thicker reaction carrier bearing with a matched carrier and shaft; your 2004 predates it, so keep those parts as a set. Check every gasket and sealing ring against what comes out, and send us the year and VIN if anything looks different. A wider-coverage option is the 2004-2014 banner kit, and the full 4L60E collection lists every fitting part.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
It is listed for 2004 4L60E transmissions, which covers the half-ton Silverado and Sierra along with the Tahoe, Yukon and Suburban that use this unit. Confirm with the transmission ID tag or send us your year and VIN.
Sonnax lists 2004 as the start of the reluctor-style stator shaft and 2003 as the start of the late-style pressure control solenoid. Buying for the correct year avoids sealing ring and gasket mismatches.
No. A banner kit has frictions, the overhaul gasket and seal set and a filter. Reuse steels only if they are flat and show no blue heat marks.
Not by itself. Converter clutch slip on a 4L60E is often caused by valve body bore wear or a converter problem. Diagnose the valve body before assuming the clutches are at fault.
Use Dexron VI ATF. Fill to the cold mark, run the engine through every gear, then set the final level hot with the engine running.
