I just changed my transmission fluid (SYN 3) on my RK after a little over 5000 miles. When I was draining the oil it literally looked bran new out of the bottle! I know the manual specifies 5000 miles, but it seems like overkill. Especially when the manual transmission fluid change intervals on cars & trucks is so high. :dunno:

Thanks Little Bear, I missed this thread and had no idea HD changed their service intervals on trans & primary.

Tranny oil looks new because it sees no combustion. It will lose it's viscosity and will breakdown over time and miles. I change mine every 10,000 miles and I know thats overkill.

I change mine every 5,000 when changing the primary and engine oil. doesn't cost that much and not that much effort. It may be overkill but I plan on keeping this bike for some time.

BTW I run 85/140 semi syn. gear oil. Shifts like butter.
