722.9 Clutch Module 2004, new and ready to install. Fits the 722.9. Ships fast from the USA.
When a 7G-Tronic in a Mercedes E-, S-, C- or ML-class has slipped long enough to cook its clutches, the steel plates between the frictions usually come out blue, glazed or warped, and putting new frictions against them is how a fresh rebuild starts flaring again within a few thousand miles. This is a new steel clutch plate module, part number 189753 (interchange 288081), for the 722.9 seven-speed automatic used from 2004 on. It contains steel plates only. Pair it with a friction set and a seal kit for a complete re-clutch.
Mercedes introduced the 722.9 in autumn 2003 as the first seven-speed automatic in a production car, first behind V8 engines and later across many six-cylinder and diesel models. Inside it, four planetary gear sets are controlled by three multi-plate clutches and four brakes. Every one of those packs alternates lined friction plates with plain steel plates. The frictions supply the grip, but the steels carry away the heat of each engagement and give the frictions a flat, true surface to bite against. A steel that has overheated loses its flatness and surface finish, so the pack engages unevenly, shudders, or slips even with new frictions.
Steels are a rebuild part, so be sure the transmission really needs opening up. The 722.9 drops into a fixed-gear emergency mode on electrical faults, and the electro-hydraulic control unit, speed sensors and solenoids cause many shift complaints with healthy packs. Scan it, check the level with the correct procedure, and look at the pan. Our 722.9 common problems guide and the 722.9 limp mode causes guide cover how to rule out the control side first.
This module is listed for the 722.9 / 7G-Tronic from 2004 on, in select applications. The 722.9 was built in several torque ratings (W7A 400, 700 and 900), and the plate count and thickness can differ between versions and model years, so match part number 189753 or 288081 against your rebuild kit's pack chart, or send us your year and VIN and we will check it. It does not fit the five-speed 722.6. All of our 7G-Tronic parts are on the 722 transmission collection page.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. Part 189753 is a steel plate module only. Frictions, pistons, seals, gaskets and the filter are separate.
It is listed for 722.9 applications from 2004 on, but pack configuration varies by version and year. Send us your year and VIN, or compare 189753 and interchange 288081 with your rebuild kit's pack chart, before ordering.
Only if they are flat, clean and show no heat marks. After a slip bad enough to burn the frictions, the steels are almost always heat damaged and should be replaced.
Early units use MB 236.14 ATF and later units use MB 236.15. Use the one specified for your transmission and do not mix them.
Yes. The controller has learned fill times for the old packs. Reset the adaptations with a capable scan tool and drive through all seven gears so it relearns.
