Leaking Tranny
Yea, I know. It's a Harley and it's going to leak. But I think this is different.
I've got a 2010 Road King. The service manual states to change all fluids at 20,000 miles. So I did.
Instead of using Castrol in all three holes, I used the HD Tranny fluid the dealer sold me and Castrol in the other 2 holes. The HD Tranny fluid is pink which is why I know that is the one that is leaking.
Drained it, cleaned the bolt, replaced the gasket on the bolt. Used a funnel when I filled it... no runs, drips or errors. Used a torque wrench and verified every step with my service manual (triple checked the torque settings). And the damn thing is still leaking. I'm 2500 miles into this oil change and my painted garage floor is pink every morning. The tranny dip stick is half-way between the "full" mark and the "add" mark. This just isn't right. Any ideas?

You're right. I wasn't specific in my description. As near as I can tell it is coming from the drain bolt. No leaks from any other tranny areas.

I put the whole quart in. When I checked it (about an hour after my test ride) it registered all the way to "FULL". I know I'm losing fluid. My floor and the dip stick both confirm it. I just think I'm losing way to much.
