1984 300sd Transmission Leak
 

Hi Mercedes Forum. I had a leaky transmission so I recently changed my ATF filter and pan gasket. I thoroughly cleaned the box and still detected a small leak from the bearing housing (?) in the attached photo. The fluid dribbles out right where the "play" symbol is on the screen shot. Does anyone know what this leak repair would entail? Thank you for your time.

PS--the screen shot is from one of Kent's super helpful videos at mercedessource.com
