Fluid in harness

[HobboR34-GTT]

Hey guys , can someone please tell me what the lower grey plug is for , I have pink transmission fluid seeping out of it and slowly filling up the harness .

 

The fluid is seeping out of the pins in the plug .

 

Thanks

Anyone ???

well, I don't know what that specific plug is for but it's kind of beside the point because whatever the fluid is will be coming from somewhere else and ending up there.  It's 2wd, right? And auto or manual?

Up high on the engine the only real leak points are engine oil from the cam covers or breathing, or coolant.  There are also breathers for the gearbox at the top bolt between the engine and gearbox, and for 4wd transfer case at the same point and front diff under the intake plenum.

Leaks you should sort out, breathing is not worth worrying about too much, particularly if you just filled/overfilled something.

Hi Duncan , thanks for your reply .
It's 2wd /auto . Rb25det Neo . it's definitely auto Trans fluid being pushed up the harness (capillary action).
When the grey plug is disconnected the car runs just like normal with no lights popping up on the dash .
My mechanic isn't too keen on problem solving the issue , so it looks like I'll have to book it into an Auto Trans specialist .

Cheers

If a "mechanic" has looked at it I suggest you find a new mechanic

Assuming they are right about it being auto trans fluid, there are a few and easily checked places where it could be leaking from. Keep in mind auto trans fluid and power steer fluid look the same so the source might be mis-diagnosed

Definatly not power steering fluid as the rack and the pump are clean as , just getting drips coming out of the harness.

Just checked the dipstick on the gearbox and it's way over the cold mark ( car is cold) so that could be half the issue ?

I'll take it to a Trans specialist tomorrow and report the findings !

I'll keep on searching what the grey plug is for ...the black plug and red plug in the pic are dry when disconnected.

Thanks for your time !

Overfilling would cause that symptom through the breather when it gets hot, so yes removing some fluid is where I would start.  Did you have it changed recently?

[Duncan]

BTW it really doesn't matter what the plug is for. If it troubles you clean it with some brake cleaner.

[HobboR34-GTT]

Yeah the tranny was drained about a month ago then topped up ...have cleaned the connection on the grey plug with brake cleaner 3 times and fluid is still being forced out of the pins ...I'll get a second opinion from the Auto Trans guys tomorrow and see what they say ...

Thanks mate

Um, trace the loom to the other end of the wrapping?
