transmission whine... Please help

**yamaha_rider619** · 12-06-2009 10:58 PM

When my 03 wrx is decelerating is has a loud distinct whine or rumble. When i push in the clutch it goes away and also when i hit the gas, it goes away too. The higher the rpm's are the louder the noise is. What could this problem be?

How many miles are on the vehicle? Does it have the whine in every gear? How about if your crusing at say 50 mph when your hearing the whine and than just throw the car in neutral and coast..does the whine go away?

This happens on my '04 as well. I only hear it in the lower gears 1-3. It does coast without whine in 4th and 5th. Worn synchros? I would like to hear some more input on this as well...

There are 115,000 miles on the engine. It whines in what i can tell 1,2,3 but maybe the road noise blocks it out in the other gears. When it is put into neutral the noise goes away. The noise only occurs when in gear and the gas is let go. As soon as the gas is pressed again, the noise goes away.

How did what I told you to try work out?

**yamaha_rider619** · 12-07-2009 12:24 PM

so i checked all my fluids, topped off my oil and filled my tires. The noise isnt as bad and as much. Now the only time it make the whining noise is when you let off of the clutch roughly.

May need to rotate them too.

**yamaha_rider619** · 12-07-2009 03:26 PM

i will definately do that soon, but i dont think the tires are causing the noise. It seems to me like it would be something with the transmission or possibly the differential.

Exactly, hence the need to rotate your tires and preferably run a couple less psi in back.

Well I am running a little less psi in the back but I will rotate my tires asap and let you know. Could my problem be the differential low on fluid or have bad fluid? Or could it be Colorado is cold as he'll lately and this just started happening?

Well last night i drove to my friends house, which he is a mechanic, and we drove around for a little while. We came to the conclusion because the noise went away that it is because it has been super super cold in colorado for the last couple days. I will be checking the fluid in my differential asap.
Thanks for your help though!

If the noise is gone when your in neutral going down the road at 50 mph..but you hear it while your in gear than I would suspect something in the trans...possibly a pinion bearing or something...What mods are done to the vehicle? Is this the original 5 spd? Has the trans. had a hard life? Either way good luck with what you find...

I thought it was the transmission too, or the differential. No mods to the tranny, but air intake, recirc BOV, carbon fiber hood, cat back exhaust, rear end links. It is the original and i bought it used so i have no idea of its past life...

I think because it has been literally frezzing in denver, it makes the noise because the differential is cold. Last night i went for a 30 minute drive and by then, the noise was completely gone. I will check my diff fluid asap to make sure its not just low.

I suppose that would make some sense....considering the gear oil in there is basically a solid when it freezing out....
