Choppy whirring
I will try to explain this noise and its occurrence as best as I can. PLEASE READ and give your best advice you can!!
Start off in first gear, begin to release clutch and apply gas, driving. Get into gear, shift into 2nd, shift into third. Start to come down hill with NO FOOT ON ANY PEDAL, and the car is rolling downhill WHILE engaged in 3rd, 2nd, 1st, 4th, 5th... doesn't matter what gear it is engaged in actually. I start going downhill without my foot on any pedal, and the transmission area under the car seems to be making a whirring noise. Seems to be coming from underneath the hump in front of the back seats, a choppy whirring noise. Choppy meaning that it cuts in and out, but is mostly consistent. The only time it cuts out is right after I release the gas before going downhill, and the car catches up with itself and it goes (whirring) (cutout) (whirring) (cut) (constant whirring the entire time I go down the hill from now until I either come to a COMPLETE stop (meaning the clutch be depressed), press on the gas, or push in the clutch at any time during the decent.
I mean, it really does it anytime that I am cruising in gear, but when going downhill you don't press the gas usually, so this is when I hear it.
So, it cant be:

Im with everyone else here saying gear whine. You can try and change the fluid to see if it goes away, or have someone redo the gear set up (backlash, preload and all that good stuff). I just put gears in my car and they whine a little, but me and my friend set it up a little on the tighter side just to be safe.

Alright, update on the situation:
I tested something new out... I will cruise down a hill in neutral, and there is NO noise, does this mean that the transmission is the culprit? I can go downhill and be in gear with the clutch all the way down and there is obviously no noise too... Gears? Transmission??
