Vehicle Speed Sensor

[Apoc]

Hey peoples i just finished changing my transmission mount over and while i was under the car i noticed that my car was leaking a fair bit or transmission fluid from my speed sensor. A drip every 10min or so. Awesome story i know...

So what i want to know is how does the speed sensor stay in place? And how is it sealed.

I can see from my not very usefull Gregorys manual and from what i saw under the car that there is some sort of metal clip that goes over the sensor housing. Is this supossed to hold the housing down as it just clips in, or is the housing threaded and screws into the box and the clip prevents it from unscrewing?

Also if i go to pull the sensor out, to change the O-rings or whatever it is that is leaking am i going to loose a gearbox full of oil out that hole?

Lastly if the sensor is drowned in oil will it still continue to function fully? my speedo does work for most the part the occasional bash on the dash gives me a 0 - 100 km/h in 0.2 seconds

i can't remember if there is a bolt or not.. pop under there and you will soon see. if ya do loose oil catch it and put it back in agian..

there should be a bolt going through a clip that holds the sensor in. there is an o ring in there. you shouldnt loose to much fluid, just have a clean rag handy to shove in the hole if needed while you clean the sensor up and put a new o ring on

So the clip is actually meant to apply pressure to the sensor housing, that the sensor screws to? Cause my looks like its doing diddly squat in that respect.

I thought the speed sensor o ring had gone in my auto so I replaced it but it turned out to be the big o ring in the extension housing and the oil runs down the housing and drops off just below the speed sensor making you think it was from there.
