722.4 Banner Rebuild Kit, new and ready to install. Fits the 722.4. Ships fast from the USA.
If your 190E, early C220 or C280, C36 or a 300-series car with the four-speed automatic has started to slip, flare between gears or take a long pause before it grabs Drive, the clutch and brake packs inside the 722.4 are usually where the trouble lives. This 722.4 banner rebuild kit covers the 1984-1997 application range and gives you the two things a soft-parts overhaul needs most: a complete friction clutch pack and an overhaul gasket and seal kit. It is the right buy when the hard parts in your unit are still serviceable and you want to put it back together with new friction material and fresh sealing.
The 722.4 (Mercedes internal code W4A 020) is the lighter-duty member of the four-speed family Mercedes used through the mid-1990s. It is a hydraulically controlled four-speed rated for about 196 Nm of input torque, with a 4.25 first gear and a 1:1 direct fourth. With no electronic solenoid pack to blame, almost every drivability complaint on this unit comes down to fluid pressure and the condition of the multiple-disc clutches and brakes that apply each gear. Those packs are what wear out with age and mileage. The friction pack in this kit replaces every lined plate, and the overhaul set supplies the paper gaskets, piston seals and sealing rings that hold apply pressure. Restore both and the unit can shift with the firmness it had when new.
What the kit does not contain matters just as much. Steel plates are not included, and neither are a filter, a band or a pump bushing. Budget for those separately if your teardown shows they are needed.
Start with the cheap checks. Set the fluid level correctly with the engine running and the fluid at operating temperature, then look at the color and smell. On these older units a vacuum leak to the modulator or a misadjusted throttle linkage can produce harsh or soft shifts that feel like worn clutches, so rule those out first. If the fluid is burnt and the slipping is consistent, a rebuild is the honest fix. Our 722.6 common problems guide walks through the same pressure-first diagnostic order Mercedes technicians use on the later five-speed, and our rebuild cost breakdown explains what turns a soft-parts job into a bigger bill.
This kit is listed for 722.4 automatic transmissions built from 1984 to 1997, with confirmed applications including the 190E (1990-1993), 300 models (1991-1993), C220 and C280 (1994-1996) and C36 (1995-1996). Before ordering, read the transmission code on the unit itself and confirm it is 722.4, not the heavier 722.3 or the five-speed 722.6 that later C-Class cars moved to. The gasket set in this kit is marked as the later 722.4 overhaul set, so compare its pan gasket and seal count to your teardown. If you are unsure, send us your year and VIN before you order. You can browse every Mercedes kit and hard part in our 722 transmission parts collection.
If your unit needs steels, a band and bushings as well, a full 722.4 master rebuild kit may cost less than buying them one at a time. Working on a newer car instead? See the 722.6 banner rebuild kit.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. It contains one complete friction clutch pack and one overhaul gasket and seal kit. Steels, the filter, the band and the pump bushing are not included, so reuse your steels only if they are flat and free of heat marks.
The listing covers C220 and C280 cars from 1994 to 1996 with the 722.4. Confirm the transmission code on the unit before ordering, or send us your year and VIN and we will check it.
It is when the slipping comes from worn friction material or leaking piston seals and the hard parts are still good. If the drums, pump or valve body are damaged, a banner kit alone will not cure it, which is why a teardown inspection comes first.
Use an ATF approved for the 722.3/722.4 family and check your owner's manual or service data for the exact specification. These older four-speeds do not use the 236.14 or 236.15 fluid developed for the later five- and seven-speed units.
Plan on a new filter, the pump bushing and any other worn bushings, plus steels if the old ones are discolored or warped. Check the band and its servo while the case is open.
