That would be my first check/fix. Always put a new O-ring on the 3 drain bolts and a dab of 592 thread selant. https://a.co/d/04zJYVWi Second would be to get a small extendable mirror and look between the primary and tranny. See if there's any sign of oil coming down there. Harley tech for over 3 years.
