It looks like you did what I did on that and turned it another half turn past tight. My washer bent up, but seems ok. I won't use clear fluid any more so I can tell easier. At least that is an easy one to get to if it is an issue. Would have find something else as that one is probably not available. Not sure why it is shaped like it is, but would think a normal copper one would work. The -37 looks like it is holding ok, and the ATF/PS should make it swell a bit. Drove it after bleeding it tonight and all seems good.
