722.6 Overhaul Kit, new and ready to install. Fits the 722.6. Ships fast from the USA.
A later Mercedes five-speed that slips on the 2-3 shift once it is hot, sits in neutral for a second before Drive engages, or has started leaving ATF on the driveway is usually telling you two things at once: the clutch linings are tired and the rubber that seals each circuit has hardened. This 722.6 overhaul kit covers both. Despite the short name, it is a complete master set: the gasket and seal overhaul kit plus a friction kit and a steel kit, so a C-, E-, S- or ML-class, a CLK, or a Sprinter can go back together with every wear part renewed. The kit is listed for 722.6 production from 2002 on.
The 722.6 makes five forward gears and two reverse ratios from three planetary gearsets, and it picks each ratio by applying three multi-plate clutches and three multi-plate brakes. Every one of those packs is a stack of lined frictions and plain steels squeezed together by a piston. Two things decide whether a pack holds: the condition of the lining and whether the piston seals and shaft sealing rings let full pressure reach it. Over high mileage and heat the lining glazes and the seals shrink, so pressure bleeds off while the plates are already slipping, and the slip creates more heat. Renewing only one half of that problem tends to bring the car back. This kit renews both halves in one box.
Two known 722.6 faults mimic worn clutches. Conductor plate failures set P0715 for a speed sensor or P0748 through P0753 for solenoid circuits and can force limp mode with healthy packs. Worn bores in the valve body also cause 2-3 and 4-5 upshift flare.
Scan first. If codes point at the conductor plate, start with the 722.6 conductor plate kit rather than a teardown. With no electrical codes, check the level hot on level ground, then drop the pan. Heavy lining debris and burnt fluid confirm the clutches. Our 722.6 common problems guide explains the valve body vacuum test that separates bore wear from clutch slip, and the E-Class shift problems guide walks through diagnosis shift by shift.
This listing is for the Mercedes-Benz 722.6 five-speed, called out for 2002-on production, which covers the later five-speed C-, E-, S- and ML-class cars and the Sprinter vans that kept this unit. The 722.6 was built in several torque ratings and the plate count in a given drum varies between them, so count frictions and steels as each pack comes apart and lay the kit plates beside them before you assemble. Read the transmission number on the case plate, or send us the year and VIN and we will check it. If your packs are fine and you only need to stop leaks, the 722.6 gasket and seal overhaul kit is the cheaper choice. The rest of the family is in the 722.6 and 722.9 collection.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
Yes. It is a master set: the gasket and seal overhaul kit plus a friction kit and a steel kit. It does not include a filter, bushings, pistons, a torque converter or fluid.
The kit is listed for 2002-on 722.6 production. Earlier units can differ in plate counts, so compare the plates during teardown or send us your year and VIN before ordering.
Not always. Limp mode with codes P0715 or P0748 through P0753 usually points at the conductor plate. Scan the car and check the fluid before you commit to a full overhaul.
Use an ATF that meets MB 236.14 for the 722.6 and do not mix it with 236.15 or 236.16 fluids. Set the level hot with the vehicle level.
Yes. New frictions change how fast each pack applies, so clear the transmission adaptations with a Mercedes-capable scan tool and let the control unit relearn over a gentle drive cycle.
