replace transmission seal
 

I'm trying to fix a leak on my 1982 300sd transmission. I have determined that the oil is coming from what I believe is the auxilliary oil pump. Does anyone have details on how to remedy this problem? I don't have any transmission details in my manual.
Thanks
Corey

There's an o-ring behind the auxiliary or rear pump (on the right side near the rear of the trans) Hold the slotted screw stationary and remove the nut, then remove the 3 bolts that also hold it on. After replacing o-ring, bolts get torqued to 8 Nm and nut to 6 Nm.:)
