No Trans Fluid
Just bought a 2007 Night Train, test road fine, got it home to change fluid. There was "NO" trans fluid. How could this be.
Concerned the trans is damaged.
Filled and rode 30 mile , no problems or noise, shift ok,
Any thoughts?
Thanks John

None on the dipstick is not the same as there being none in the transmission case.
Now, if you pulled the drain plug and nothing came out, you'd be able to say there was indeed none in there.
So, I rather suspect it was just low, which isn't the end of the world. Would be the question of why it was low, but it could simply be long term neglect.

Back in 2007 I had some warranty work done on my 05 Road King.
The dealership had drained the transmission.
When I picked the bike up I did not check all the fluids.
When I got home, after a 45 minute ride, it did not seem to be shifting as smoothly as normal. I checked all the fluids, the dealership had forgotten to refill the transmission.
Fortunately I had been running Redline Heavy shockproof w/ a Petron additive, and it still had enough of a coating in there that I rode the bike another few years and never had a problem in the next 40K miles before trading it in.
I did speak with the dealership about them forgetting, and got a 5 year warranty from them (in writing) on the transmission.

Clearly it didn't do it any good but short of completely tearing down the tranny and doing a full inspection there's obviously no way to definitively say there's no damage from having no oil. If you've put 30 miles on it since filling and it has no symptoms then chances are high that it's fine, only time will tell if something crops up in the future.
Did you note how much you needed to put in to get to proper spot? Did it leak or did they forget to put in?

If you didn't drain it, it's probably a good idea to do that. Replace the o-ring on the drain plug.
This can be done with the bike on the stand. Put a short piece of paper towel cardboard tube up between shocks so oil does not make a mess.
I break plug with ratchet and then use a long Allen wrench to remove. Hold bike upright to finish drain.
Be sure to check primary to proper level, bike upright, cold primary, and fluid at bottom edge of clutch diaphragm spring. Primary takes 26 oz.
That may be where your transmission fluid went.
Nothing works better year round then Harleys's non detergent Formula +. Just the conventional one. You don't need the synthetic one.
Don't over tighten plug. Use correct o-ring. That's a special MS fitting. O-ring goes up in bevel. That face of plug torques up metal to metal so it doesn't vibrate out..
Check that black vent hose on the back on the transmission that goes down on left back side. Run a soft coated wire up it. Make sure no mud robber has plugged it.
That's the primary and transmission vent. Primary vents thru a passage way to transmission (clutch push rod also shares that passage way.
That shaft the passage way is in is the input shaft from the primary driven by the primary chain.
That input shaft runs in the output shaft that turns your small cog drive pulley sprocket for the belt back to the rear wheel.
Marvel of engineering and it's pretty tough. If you had some oil in it, your probably OK.
