Clunky Changes/Stuck In Gear When Warm

[KillerHERTZ]

Been having issues with the C220 CDI (S203) once its upto temp. - I believe its the: 722.699
Gear changes become clunky and occasionally it gets stuck in 2nd. As soon as its cooled down again it runs fine. I have scanned it with both iCarSoft and Xentry which didnt flag a single code.

Looking at the bottom conductor plate, it looks extremely oily, could it just be a case that it needs a full clean down/fluid change? Anyone have any other ideas what it could be?

Cheers!

Hi is this the trans plate your talking about

I would suggest a full gearbox fluid and filter service first including replacement of the electrical plug connector known as the pilot bushing. If the connector plug is wet go and clean out the TCU in the passenger footwell also as its likely filled up with gearbox oil caused by the pilot bushing leaking.
