CLK 320 W208 Transmission leak

[Avidd]

Hello, I'm trying to resurrect a w208 320 that has sat over the lockdown period.
Among other issues there's fluid over the transmission pan and a patch on the ground where it sat.

I've got it on friends ramp and just looking for any ideas on where to start - replace the pan seal?
No error codes.

Thanks

Transmission fluid and filter change. Have a look for threads on atf and fluid wicking up a cable to aswell. Might need to change a seal to that too.

The electrical connection that goes in just above the sump pan is a common leak point
