I am going to yet again try to replace the pan gasket on my 1986 2.3-16v W201 automatic transmission to stop the fluid leak. This last one took about 4 months to leak. Can someone give me the torque spec for the pan bolts so I can try to get it correct this time. I think I got them too tight and split the gasket.

Hammer the area around the holes flat before you install. You probably dimpled it. If you do it right, it won't leak. I did my 280SL years ago - still dry. I hate leaks

Thanks I'll check it for flattness, I actually bought a new pan last time so i should be able to get it nice and flat. I thought I was careful about the torque too, but here it is leaking again...My others have never leaked no matter what I did, this one loves to leak apparently

For those of you who don't know, while MB indicates the torque as being 8nm for the transmission pan, that translates to 6 ft-lbs or 71 in-lbs.

my 2007 tranny pan bolts have to be replaced each time the pan is dropped. They are a stretch bolt and only stretch once..
