Hi. Hope someone can help me identify a a part to repair a transmission leak. It looks like a plastic plug located over the trans pan on the left hand side. I was also wondering if anyone had an idea as to how I could properly remove it. Thanks.

This is the passenger side , right?

If so that is the hole where the gear oil dipstick goes in.

If you don't have it, go to a bone yard and get one.

O.

These pics should be what you are referring to. I never had to remove them.

Snap ring and plug. It looks like the bottom one has an O-ring on it.

I would try cleaning them, remove the snap ring, clean again, and use a small suction cup (maybe with a little oil on it).

I don't know if tranny oil will run out of the bottom one or not.

Exactly what I was looking for. Thanks a bunch. Do the diagrams come from a site that has links to manufacturer part numbers?

Thanks again.

You can get the Factory Service Manual here.

I have found some older FSMs that list part numbers.

You would have to look at a Subaru web site to get part numbers. I looked at one and nothing was listed for the 4EAT transmission. Google "Subaru parts" and you will see subarupartsforyou subarupartswarehouse and a whole bunch more.

If you get the lower plug out, a local auto parts store should have O-rings.
