Neutral/Park safety switch replacement
A few weeks back I was stranded 50 miles from home, the problem turned out to be a faulty NSS switch preventing the car starting.
After initially shorting out the switch to get going, I got round to replacing it tonight. Luckily I had a spare switch from my old 350 engine/gearbox.
Here are the tools I used, 8 and 10mm spanners, socket wrench and a flat headed screw driver for levering.
Here is the switch on the side of the gearbox, tight access.
Releasing the switch from the shaft with a 10mm socket.
Releasing the bottom fixing bolt 8mm.
Releasing the top bolt 8mm.
Once the bolts were off, the switch could be levered off and the connector was released.
The connecting rod was then released from the stick bush and the entire assemble was removed.
Reassembly was done simply in the reverse order with the replacement switch and link.

Good post. Not easy to get to the linkage clip under there. Not much on the trans in the EGv 107. Good job.

It Is What It Is, Dude
Where do you guys think it should go?
There is no trans section in the EGv107, 'cuz I copied the online Service Manual system and there's no trans section in it.
So what about Section 54, electrical, or what?
We do have Drivetrain...

Drivetrain would be good. Or electrical.
A trans section would be best. I know there have been posts on the modulator valve and trans. mount. Pretty sure someone did a post on trans filter and draining torque converter. My brain has been rattled around the last couple of days bouncing in a tractor mowing and raking hay.

A little off topic. But when I changed out the transmission in my 560. I had a heck of a time finding anything on the transmission. Finally found a PDF file in line that covers it.
Here it is if someone wants to put it somewhere.
Well it's too big to upload, if someone wants to e-mail me for it you can have it.

I'm currently wrestling with symptoms of this very same issue (no start). I just replaced the bushing on my linkage. http://www.benzworld.org/forums/r-c1...ml#post4969390
My car is a 1981 380SL. Looking at your pictures, the unit your calling the NSS, where the linkage connects onto the "stud" from the unit. I have that same unit, however what perplexes me is that online pictures of the NSS are not that.

This part I do have on my transmission; is it located right beside where the linkage assembly your showing was removed from.

Look a little deeper on the performance products website... rarely do I rely on pics from a parts house...

Where is it again that we are going... And why are we in a handbasket?

I'd recommend you shop elsewhere, or confirm part number. ...or you can order from performance products, an otherwise reputable parts house (in this case something is amiss, either the picture or part fitment).
Better yet, contact Mercedes Parts, Mercedes-Benz Parts for the part... not listed on his online catalog, but online only has a portion of what he has available. Then there is always the dealer...
