Neutral Safety Switch

[ODZKing]

My wrench is adjusting my exhaust for me on my 73 so I asked him while it is on the lift, see where the tranny fluid is coming from.
He says the neutral safety switch is leaking. My guess is the O ring is shot.
Either way parts book says 2932820. Seems like the standard switch all 727s used.
Napa crosses to this:

Anything special I should tell him or should know? Unscrew the old one, let it drain a bit, put new one in - done, no?

There is no O ring with the 3-prong NSS, it seals to the case with a rubber-coated cupped gasket. Switches can leak where the plastic insulator is crimped in the metal case, in that case the switch must be replaced.

If the gasket is faulty, a little RTV will help.

Switch replaced, exactly as stated, the plastic had separated from the metal casing and leaking.
However there was an O ring on the old one and we replaced it with an O ring that came in the package.
