2005 acura RL 176000 miles brand new redline transmission fluid



before I go and buy a replacement driveshaft I want to see maybe its not the driveshaft at all

heres the video of me on the freeway it gets louder when I step on gas and almost goes away when I let go
happends at exactly 70 mph and I belive around 35-40mph also

very loud and annoying since theres no other noises sometimes it sounds like one of those little wavy birds that run around the grass in Hawaii...

 

I have that on my 06 civic as well. It's not going to be drivetrain related. I think it has to do with the wind tunnel effect when the car leans forward. Somehow it's pushing air over or under something and causing the whistle. I wouldn't worry about it.

 

its happening at any speeds just not as obvious. i hear it distinctly at certain speed
exactly at 35mph and 70mph which is odd. but i hear it at other speeds very quietly its like a harmonics. i would say next resonance would be at 140mph but im not trying to go there for science lol

im gonna check to see if it peaks at 17mph also

now that i think about it maybe the bearing in transfer case that holds the driveshaft?
