I have no reverse/backup lights. Jumpering the wires on the tranny mounted switch gets them to come on, so I figure the wiring is ok and the switch is flaky. I have no knowledge about the internals of our trannys, so before I replace it I wanted to verify if the switch is immersed in fluid or dry. If wet, I'd just plan a gear oil change as part of the process.
Thanks for any insight. Bryan |

Unscrew it. There is a 6mm pin that wears down. Probably the culprit. You can fab another one from th shank of a 6mm bolt or get in touch with @bdstone914 on this site for another unit. (IMG:style_emoticons/default/beerchug.gif)

it sits right around the same height as the filler plug on the other side. Put a pan under it, have everything clean, screw out old part then screw in new part. Then if you did lose a bit add it in the filler plug if the amount makes you uncomfortable.

(IMG:style_emoticons/default/beerchug.gif) @burlybryan @76-914 It is smaller than 6mm. I think it is 3 or 4mm. Just buy a new one for $20 from Porsche or Pelican. Thanks for the referral but i dont think i have any and not worth reusing. Part number 90530324502 |

Thanks guys! Perfect information. Makes sense that it's about level with the fill plug.
I have a new switch and tang/rod already, so I should be good to go. Bryan |
