I have read through many searched threads and found a bunch of similar posts, but they all had something unique about them that didn't quite fit in with my problem.

I have a winding/whining sound only when in gears 1-4 while accelerating. When I release the gas, it dies down and hear nothing. 5th-6th, I don't seem to notice it, maybe because of road noise, etc., but I couldn't hear it. As RPMs increase it gets louder.

I have an 05' with 80K miles, manual. Never heard this sound until now. Before I take it in, was wondering if anyone could give any insight on possible problem.

I have read that it was normal to hear a "whining" sound on the 8, but with 80K miles for it to start?

 

A little update. When shifting from 1st to 2nd to 3rd to 4th... the whirring noise stops when I go into neutral, and when just as I am putting it into the next gear, the whirring noise will kind of have a "burst" when the next gear is engaging.
The sound is similar to that of the little toy cars that you push forward and it gos. (if you understand which toy I am talking about)

 

I would check the transmission and rear diff oil. Especially the rear diff, I just changed mine at 60,000 and it was almost black. On the diff make sure you clean the magnetic drain plug. They both use 75/90 Transmission oil. I used Mobil 1 for mine.

 

If this sound is heard while you're shifting, its the synchros spooling to match the gear speeds.

 

The fluids looked fine, didn't see any abnormalities.


Is the synchro syncing something I should avoid driving the car in, or is it alright for the most part?

Also, I have noticed there is kind a fairly loud whirring noise (kind of like a rough idle sound with out the physical roughness, if that makes sense) when the clutch is not pressed, and goes completely away when pressed on idle. If I rev up the RPMs in neutral, I can still here it. I do not notice it when the car is in gear.

I live about 80+ miles from a real mechanic shop, and I am afraid to drive it. Just trying to boil a diagnostic to see if it's needed to get a tow (which I am trying to avoid) or if I can drive the distance without messing something up more.
