Grouchy Neutral Safety Switch
 

So the original Neutral Safety/Reverse Light switch in my 240D bit the dust. I got a new one the other day and installed it. It works alright, but jeez is it finicky. I usually have to jiggle the shift lever a little in park and neutral to get it to gap the switch. Reverse seems to work fine. I've tried adjusting it with the panel thing, but the switch has such a small range where it makes contact.

Is there a trick to adjusting these things? Do they break in over time?

Did you check your shifter bushings for wear? they get loose, and or fall out, then the shifter doesn`t move the lever for the NSS to engauge, or the transmission into park.

X2 for bushes. Also make sure the plug is good & clean and the pins are tight in the sockets.

Hmm, the bushings seem alright. Though they're cheap enough and this is aggravating enough that I should just replace them.

The plug is a-ok. I ended up refurbishing the whole thing after the plastic crumbled.

How do you fix Neutral Safety Switch?
 

Hi I have an 87 300TD and It only starts on neutral.

I hear its the Neutral Saftey Switch. How would I go about replacing that, and how much should It cost too have a shop do it?


Thanks

They are pretty much plug and play. Been a few years since I did my 85, but as I remember I removed a plug, some screws and put it back together.

here is what it looks like.

You will pay quite a bit more for one if a shop replaces it for you. mark up on the part, and probably one hour labor. the shop I sometimes use is up to $117.00 hr.
