Hi Eric,

Yep, that looks like the switch out of a M47 manual transmission and it looks like the one in the pictures to cut the shoulder back on.

So yes, that’s the one I remembered that screws into that cover plate on top of the gate selectors.
The switch itself never failed me since then.
I have two of these transmissions and the wiring to one of them went bad.
I’m thinking my switches had the plug socket that’s the same used on the windshield washer pumps.
Am I remembering wrong?
So this new switch is a total change out then?
Between either one, I hope it got the reach on the plunger right.

Definitely didn’t know about later revisions but that can transpire at anytime on any car.
They use a disclaimer, in the lower fine prints, to making changes “middle year” on all production lines.
Sometimes it just within a vendors production and cascades.
Volvo doesn’t have any control over so the disclaimers either, so this all runs far and wide throughout our civilization.

I’m trying to remember how big the threaded portion was but if it would fit in a drill chuck a person could try using a rotary tool like a “Dremel” Brand name and scuff it back some with a cutoff tool disc.
Just as long as you try to keep it evenly will help but holding on to the hex is ideal.

I will say I was cautious in how much metal to remove but the bottom inside of the switch casing should have some extra distance of metal for torquing strength not that it needs much.
I stopped at .025 or so.
Don’t remember if it had a gasket to toss too?
I moved it in about thickness of a match book cover or a big man’s thumb nail thickness did the trick. (-:)
The plungers seems to back up plenty towards the contacts it just needed the extra holding power.
As you can see the plunger doesn’t stick out a whole bunch.

Good to hear from you and hope your business is doing well.
I keep you in my mind as my cars are getting older and you are a good source for everything of knowledge and them parts! :-)

Phil
