Mystery Transmission Line- 2007 S80 3.2

Post by Skymongrel » Tue Mar 31, 2020 4:25 pm

This post is in reference to my recently acquired 2007 S80 3.2 6 Cyl. (121K).

I discovered an oil leak of some sort along the side of my transmission at the driver side wheel well. I can spot a plastic tube going into the side of the transmission where the leak seems to be coming from. I can't get to it without removing a lot of stuff up top; air box, battery and battery box. So before I expose it completely I need to know what this part is and how to fix it. I'm assuming maybe its just an o-ring that needs to be changed. Or maybe I'm seeing that the tube isn't well seated from my pictures and a gently nudge might do the trick!

These pictures are all shot with the driver's wheel removed and looking towards the front of the car from behind the LH axel. Any help identifying this tube would be most helpful!

I removed the airbox and battery box to get a look at the line/tube/hose in question. I appears to be a vent line. It is about six inches long with a vent cap on it and terminates at the base of the battery box. I could see no way to easily remove the fitting that mates with the transmission to address the leak. I reattached the loose clip and repositioned the line and will monitor.

Here are some terrible pictures

Take a look at this eBay transmission for pictures of the breather tube

Yes! That's the one! What a good picture. Thanks. Now....how is that tube removed? Just a press fit with o-rings? Mine is still weeping and of course it looks like I'm losing more than I am.

I looked to see if I could find this vent from another source (i.e. Aisin, Mazda, Ford, Land Rover, etc.)

All I found was information that indicates its a press fit.

The Vendors that rebuild Transmissions must have a solution but I couldn't find it.

Let us know what you find out.

Thanks

Paul
