The W204 C63 AMG 7-speed transmission has officially reached its breaking point… and this time, there’s no bringing it back. After multiple failures, tear-downs, and rebuild attempts, it’s clear this unit is DONE. ☠️
In this video, I break down exactly why the 722.9 transmission in the C63 AMG is not rebuildable, what goes wrong inside, and the symptoms that finally confirmed it was beyond saving. From valve body issues to internal clutch damage, this is the full story of how this gearbox tapped out for good.
If you’re dealing with slipping, harsh shifts, failed adaptations, or repeat failures on your own W204 C63, this video will save you time, money, and frustration. I’ll show what to look for, what can and can’t be repaired, and what the realistic fixes are when your transmission gives up.
Watch the full breakdown and see why this C63 finally said “no more.”
