Tranny oil leak through main plug

Recommended Posts

Has anyone experienced transmission oil leak through its main plug? Connector is full of fuid after disconnecting. No other spot seems to make sense. Thx. Milan

Is it excessive? 

Rather common among many transmissions. 

It would require harness replacement if it bothers you, or if it causes issues(rarely), or if it is actually pushing out.

Just my opinion

Wiring is completely wet from fluid which gets into main plug and leaks out undre car. Large puddles. Will check with rockauto.com what they got

Ok I would highly suggest that you check your vent at the top of the transmission.

It may be plugged causing the excess pressure to push out of elsewhere. 

The vent is on top, look for a hose with a steel cap that spins. 

Pop it off the transmission, check the fitting, hose, and vent for blockage.

Also check your fluid level to be sure it is at the proper level

Yes, I have seen this, and discussed it in a prior thread.  It is not over filled.   It is leaking down the wires and into the plug  @milansky

Look down this page and I describe the same thing.   I simply cleaned both sides of the plug, I took it apart and cleaned it with contact cleaner and dried it with compressed air.  The only way to solve this is by replacing the harness.
