gear oil leaking from speed sensor

[IceMochaBowl]

i have a 95 s14 and it is leaking gear oil from my speed sensor. it looks like the speed sensor is all the way in but for some reason oil is slowly dripping from it. the little rectangular stick is in there so i don't think its that. any ideas?

thanks in advance for the help!

Get the car level and pull the side plug to see if any oil pours out, could be too full. Pulling the side plug of the transmission while the car is level is the best way to know if there is enough gear oil in the transmission. I have had that issue as well which was solved by the replacement of the speed sensor, but you may try to make some kind of gasket

Bad or failing o-ring... Pull it out, replace o-ring and slide it back in preventing any damage to the new o-ring.

thanks for the help. my speedometer wasn't working so i just replaced the whole thing. no more leak.. BUT my speedo still doesn't work! i checked my cluster. all of the plugs are in there all the way, although it does look like a couple of those strips look a little fried. maybe its that? or the harness connecting to my tranny was completely cut up by the previous owner so maybe its that. if any of you have a solution of test for this that would be awesome. thanks again!

What a waste of a thread, probably the oring on the sensor.

well zombiewolf, what a waste of a reply.. if you couldn't tell by reading my response to the helpful people, that problem has been fixed. Sorry i am not all knowing when it comes to my first 240, and couldn't find any info or solutions from the time i searched it.

judging by your response, you must know a serious amount about 240's.. with your vast knowledge of this car i'd hope you have a solution to the problem with my speedo that i mentioned in my response. it seems like you didn't read it, but if you go back to read it, and have any quality input that would be great :)
...if not. do EVERYONE a favor and please leave the unnecessary negative comments to yourself. :D
thanks in advance!

Pretty sure i answered a question that should have been in the small questions thread. You can use google to find the answer on how to fix electrical issues instead of being spoon fed. Ill give you a hint: multimeter

Don't listen to that ^^ guy... Them devildogs like to get their overabundance of testosterone and lack of pussy out any way they can... The good news is that those very same guys WILL save your life downrange without thinking twice if you are ever unfortunate enough to find yourself in a very precarious situation (experience talking)... so even though they can come off like real pricks; you need to know that they are a different, purpose-built breed... Be thankful for them- they really are good at what they do ;)

Get a meter, put it on the VSS and make sure it puts out (AC) power when you spin it w/a drill. You can also try a different cluster if you have access to one. Always sucks dealing with some other fucker's science project. Last (and best) option besides doing full continuity checks with the FSM IMHO is to get a Wiring Specialties or equivalent uncut, unmodded lower harness. This way you can be 99.9% certain that the wiring is correct and all going to the correct location(s). Could save you loads of future ass pain.

I read ass pain, then hear someone fart! looks around reads ass pain again! kid from the "superbabies" playing in the background says "sorry about that!"
Just sharing!

Ok I agree with mike on the testing, but that harness for the trans is not that complicated. If the problem is in the lower harness. I would consider it an easy fix. I would see if the ecu sees the speed signal before, I tear out the cluster.

[Mikester]

^^Totally agree Snoop- but the problem I see is that according to the FSM, the speed signal goes thru the speedo before going to the ECU. NTM the diagrams in the FSM for this leave a lot to be desired lol...

Anyway, I recommend a fresh lower harness because [with few exceptions] it basically resets everything exactly to OEM spec without having to do a bunch of metering, pulling stuff apart etc... and I'd wager a fresh harness may be more OP's speed considering the nature of post #1.

[cotbu]

I agree, but if the signal is at the ecu, then we can assume that the cluster is bad, not the harness.
