You said it worked in the past? why are you changing it then?
My 72 B body had an earlier trans than I thought. The trans is from 68. I put a 3 pin NSS in and it worked but the reverse lights were on in D. I'm gonna search for a single post to correct it and just go with no reverse lights.
the switch worked in the donor car it was in, tranny sat on the garage floor for a few years. Doesnt work now spring doesnt push out the plastic plunger anymore. 73 trans 73 car 73 replacement switch.
