Drained my ATF pan today, wanted to change the crush washer but could not find the right size at local parts dump, did not make trip to dealer.

Is there a generic size for this [11 mm ID?] Also one side of mine has a circular inlet between ID and OD - don't know if this goes to the pan side or bolt head side?

This is maybe 6th time I have reused the same washer - if the stealership doesn't want more than a couple bucks I may buy a few for future drains.
