I was reading this tread and seem like my problem is related to this neutral switch. My neutral start switch is leaking fluid from the rod, the lever from it is not connected to anything and rotates freely, i can pull the lever entirely out with the rod from the tranny and the fluid starts coming out, if i put it back the fluid stops. I can see a seal. I'm not sure where the other end of the lever connects to. the car starts and i can move it back and forth. Also i noticed that the accelerator pedal has this section like a lever that is touching the exhaust pipe, but not connected to anything either.. is that where the lever from the tranny is supposed to connect to? any ideas how to approach this? any help it's appreciated.

The NSS is not your main issue at this moment.

This lever is your gear selector = if it falls off...

The problem is inside your transmission, a fastener has come loose, allowing the arm to come out.

Remove the transmission oil pan and check for loose/missing fasteners or mechanical damage.


Have a great day.

Neutral Safety Switch how would I go about replacing one?

And how much should It cost for a shop too replace one?

:EDIT: 1984 300SD.

Thanks,

Tony

If the shop charges more than one hour Labor = run away, they are crooks.

Any idea if the NSS is the same between 1986 300SDL and 1983 300SD?
On APE the parts seem the same.

I am diagnosing "no reverse lights" on my newly acquired 300SDL.

Thanks.

Thanks for the follow up reply.

I am not really sure what the answer is here.

The part numbers listed appear to be different, but possibly the same. When I look the parts up I am given the same part number. It is also possible that I order both numbers listed here and get the same box. yes?

I am weighing if it is worth the effort to remove and install 2 switches.

Again, thanks for the help.

On my 1975 280c, I have removed the NSS however i can't seem to be able to put the new one in... I have the correct part and everything just cant figure a way to get it over the rod. Any ideas??

More data = pictures needed for this issue/question.

I saw this thread and thought someone could help. I have a 1980 300SD and the NSS switch PLUG has deteriated. The switch part number is #000-545-4606, but I can't find the electrical plug part number that goes in it. Even the guys at Auto****AZ and Shumaker Mercedes don't have a clue. Any help is appreciated.

I just looked throu the EPC, and could't find anything on it. The EPC for the 116 is slightly less organized than the 126. Try getting in touch with Lee or Roy here on the forum, I'm sure they can find something for you.

Hi all

What I need is the part number or where to fing the NSS PLUG. Do I have to buy part of a wiring hanress? Mine deteriated and falls off.

This is the PLUG/hard shell that holds the spade connectors which you attach to the NSS.
