Might be a speed sensor, them boxes cause all sorts of problems...

When was the fluid and filter last done ?

Cheers.

Torque converter is the oil pump for the auto transmission. so you have to change it .

Just change the gearbox oil and filter and it will be OK, do not go over expensive vanity!

RE: Mercedes w211 automatic trasmission problem
P2512 Actuation of torque converter lockup clutch is not possible. Need torque converter. Try resetting all Reset of adaptation data and Actuation.

If it does not work then get a new one.

After replacing the torque converter, the converter adaptation data must be reset as follows:
Access Xentry/DAS Reset of adaptation values -> Torque converter ->
Confirm torque converter replacement with Yes -> Confirm reset of adaptation data with Yes
Access ETM >Electronic transmission control (722.6) -> Transmission adaptation -> Reset of adaptation data (torque converter lockup
clutch) -> Confirm torque converter replacement with Yes -> Confirm reset of adaptation data with Yes
