I have a 2000 E320 with 190K miles and rebuilt transmission at 160K but out of warranty now and leaking like a sieve through the rectangular plastic covers bottom of fly wheel housing. I believe the fluid is transmission and the leak occurs when the engine is started where the fluid almost pours out of the covers. The leak is not coming from the electrical connection/oring near these covers as I have confirmed that. Does anyone have any ideas on this. Feel like I need another trip to the transmission shop? Also, had just replaced the shifter for spilled coffee and was on test drive when I noticed the fluid leak. Any help is appreciated.
Thank you

 

Hello - it is likely the electrical connector plug. I would try to address this right away not to cause any harm to the trans. it self.
