Hi i have an issue with C63 2012 70000 miles with 722.9 MCT transmission which started to slip in all gears. my icarsoft scanner showed codes for each gear slipping and also 0606 -yn3/8n4 vgs control unit and 2761- y3/8y9 start up clutch control solenoid.
Changed the trans fluid and filter nothing untoward found in the pan and magnets drove 5 still slipping mostly in gears 1-4 then the engine management light came and stuck in 2nd gear.
Restarted the car drove 100 mtrs then lost all drive forward and backwards, again same faults showing along with the message TCU had communicated with the ECU (hence the EML had come on)
Pulled the valve body and sent the conductor plate to sent to ECU Testing they found no faults. Refitted the valve body and replaced all 8 bosh solenoid and still no drive.
When started the car from cold in drive it will creep tick over forward 4 mtr and reverse 4 mtr then nothing at all as if in neutral am leaning towards the wet clutch replacement but Would really appreciate any thoughts and advice as I'm leaning towards having to replace the wet clutch next
