Past few days I've been noticing a whining sound coming from the engine bay. I have no idea what it is. When in gear and I drive I hear it. When in neutral I rev it, I hear it. I have no idea where this sound is coming from. My crx drives fine with no problems. Does anyone know what it might be or can point me to the right direction? TIA!

 

It could be a belt, or it could be the transmission. does the sound go away when you depress the clutch pedal?

 

no it only happens when I gas it.

 

I'm no mechanic, but sounds kinda like a vaccum leak.

Is it a whistle type sound, and is there any difference in engine power, control etc..?

 

ummm... I'm 100% sure its not a vaccum leak. I have a feeling its from the tranny but not sure. Its had to explain but its like a whinny sound.

 

When my tranny was running low in fluid, I ran it for about an an hour and 1/2 on the interstate.... I'm messed up, I know. But during my rebuild, the bearings sounded like skateboard bearings (if you've ever heard them). It was bad. But I learned my lesson.

Mine was mainly in 5th, I really noticed it just cruising through town after the interstate run; only going about 40 or so. WWHHHHIIIIRRRRR. Put some more fluid in there, or get some new bearings. Heh. Or maybe later a new transmission... It may not be your problem but just giving my .02. I'd definitely look into it.

 

Weird thing is, I just did a tranny fluid change. The guy put 2 quarts of 10w 30 motor oil. Its started making the sound after that day. Is 2 quarts enough?

 

10w 30 is motor oil man. If I'm correct, you need gear fluid, like 80w 90....

 

haha yea he's right^ i get that sound too under high rev...check your alternator belt or your ac belt...its nothing bad its just your alternator belt and ac belt could be really old and crappy

How come the guy at the parts store told me 10w 30 motor oil for my tranny fluid? Does this mean I possibly fuc*ed something up?

 

the parts guys always say use normal motor oil for trannies in our cars (idiots).
if the noise happened right after a fluid change thats most likely the problem. Go buy some GM synchromesh (local gm dealer). This stuff is great !

 

so I can mix it with the oil or do I need change the tranny fluid again? I'm not familiar with this stuff.

 

10w30 is the right oil to use in your tranny, so don't worry about that. you might want to run honda mtf or something better if your tranny is making noise. i personally run the redline shockproof lightweight. that stuff is awesome (pics to come one day)!

10w 30 is correct per the service manual.

 

hey guys, I just took a peak under the hood. It seems as though when I rev the motor its coming from the pulleys. Maybe its time for a belt change? Sounds more like its coming from the altenator.

Yup- that's what I thought, either tranny or a belt. Just do a quick belt change & you should be good to go.
