I was searching for the transmission oil pan drain plug gasket for my Forester XT - 15 and found this one:
Part Number: 803916100
Gasket 16.3x22x1.0
Material: not sure

Also, acording to some pictures on Internet, engine oil pan drain plug gasket is very similar to transmission plug gasket:
Part Number: 803916010
Gasket 16x21x2.3
Material: aluminum

By comparing both engine and transmission plug gaskets, they have different measurements but very close.
I don't have any of them so I can not really check their fitment.
I wonder if they are interchangeable with each other.

Have anyone tested out?

Iirc, they’re very similar. But why not just buy the correct part number?

@Theseus161, transmission plug gasket is not available in my region.
But the engine plug gasket is widely available and cheaper.
