Seems I got a leak at back where some plug connects to the tranny... app this can suck the oil back into the ecu gubbins inside so not something u want to leave faulty, Ive searched and have come up with zero (surprisingly as tech said it is reasonably common issue) and looking at having this sorted any clue what the fault issue is here?

Cheap DIY fix.

This has been a problem on the 722 transmission since the w210.
Very common to have a leak where the electrical plug connects to the transmission.
Mercedes has a redesigned the socket part of the plug to prevent the leak and the ATF from going up the loom to the TCU and causing shift problems.
There are a few DIY on this, I'll try and find one.
