Hey guys I'm a long time lurker and this is my first post. I have an issue with my 86 300SDL 722.3 trans. it's leaking from a plug behind the shift lever module (driver side). It's not from the actual shift lever seal. It looks like a Steel plug that's flush with the transmission case (rusty). Fluid is weeping out slowly and making it seem like the rear of the trans is leaking. here's a picture. Any help on how to seal it would be greatly appreciated.

Thank you
Ryan

Been there done that but with tranny in car. Much more difficult than yours with it on the bench.

Aw thanks so much !!! i just grabbed that picture from the internet. My trans is mounted on the car so it looks like im going to collect all the o-rings i need to do while im already in there ill do the Bowden cable oring and whatever other O ring i can change. I dont feel like pulling the valve body out over and over.

Thanks a bunch. Looks like Im going back into the trans for a deep dive...

OH LORD. cant wait for the day i have an electric car without a darn trans.

*sigh* the battles i do to not have to smog a car in So cal !!!
