Ok lately I have been hearing this loud whining noise when I press my gas pedal a certain amount. It seems only when I press it half way. Any less or any more and the sound is gone. I'm thinking tranny maybe?

It's a 98 civic with GSR swap and GSR tranny.

 

Where is the sound coming from, it could be from anything. Does it only happen while driving? Does it happen when on idle?

 

Only happens when driving forgot to mention it doesn't make the sound when reving at idle

 

Gears are whining? Maybe your bearings are getting worn and the gears are starting to mesh funny. Could be the differential.

 

check timing-belt tension.

 

The timing belt can whine? I didn't know that

 

is not the timing belt. it is the tension on the belt. if the tension to big it pulls the camshaft to much. have u recently replace timing belt or waterpump check it!!!!!

 

Yes the timing belt was recently changed last month

 

The whining I heard under hard acceleration was coming from the passenger seat. I fixed it by dropping my wife off at the house.

 

nice 13g...mr2, you have a cold air intake on the civic?

 

13g? And no I have a short ram intake.

 

having a cold air intake or even the short ram you have will pull the air harder than the factory airbox or intake, causing a whistle sound when the air goes past the throttle plate when you press the pedal about 50% down... with the car running, listen for a whistle sound whenever you crack the throttle by hand... ust a theory but that could be what youre hearing

 

this!

i have this very same sound on my car. stock d16y7 and i modded the stock intake a little and now i get that "whine" sound with my pedal halfway and usually around 2.5-3k rpms. nothing to worry about really and now i have grown to like it

 

yea so no need to spend any money on parts that dont need replaced
