Is anyone else have a noisy 6 speed. I guess noisy isn't the best description, but it isn't silent either. No real definite sound, but you can sure tell there is moving parts under you, but maybe it is normal. I can coast in neutral and the sound is still there until you stop so it isn't just happening under power. Also, I'm new to the NV-5600 world. How and where do you check and change the fluid? Didn't crawl around much, but nothing really stuck out either.
TIA
