I have a 1993 Goldwing 1500I. The right side folk has leaked oil near the anti-dive area. I live in Italy and it isn't that easy to get things shipped from stateside to Italy. With that regard, may I use any type (detergent or non-detergent and are there different grades) automatic transmission fluid to drain, clean out, and replace the fork oil fluid (left and right side) in my Goldwing 1500I? Greatly appreciate the feedback.
