904 transmission pan gasket

RedFish said

Dipstick tube on passengers side, Selector shaft, speedo input, and more on drivers side. My point is so many places above the pan can leak. The fluid runs down wicks along the pan gasket and pan. Of course the leak can be the pan gasket but it will pay to closely inspect for a higher source of the leak.

Agreed.
I used to be in the trans business so I am pretty good at determining specifically where leaks are coming from.
Yet still it's really hard to tell for sure sometimes.
If it's questionable I like to wipe the area down and spray a little aluminum bomb on the area and go back to check it after a drive. (dont paint it, just a light barely noticable coat)
the fluid leaves a real definite mark where it leaked and ran the paint, or a easily seen circle around an area such as a band stud nut or cooler line case fitting.
