Its not a good idea to use an offbrand conductor plate in the transmission, its only a plastic tray with copper tracks and a couple of hall effect sensors in it. But the OE parts are better materials

The leaking plug is usually from a worn out O ring on the plug socket which is sold separately, its not too expensive either. And always buy a new genuine one. The plug socket has 3 updates till today - the last one sold by MB or dodge is the correct one.

dodge sell that connector socket for 15 or 17 near my place and the plate too for quite a lot lower than the mercedes dealers here.

just ask for a 09 dodge charger transmission plug socket.. the chargers, challengers, jeep cherokee etc have the same transmission as ours. - the parts will come in mercedes packets.
