So yeah, 6 speed may be coming sooner than I expected

I have this ticking/whirling sound I hear coming through the shifter that is directly related to speed. The faster I go, the louder the noise is. Doesn't matter whether the car is in gear or not and the only time it goes away is when I come to a stop. You can also hear it from the outside when the windows are down.

I'm guessing a chipped tooth on one of my gears, huh?
