When I drive my Evo and I up shift and everything is fine. Well when I downshift from an rpm above 3500 in any gear it makes this weird almost wining sound when the clutch starts to grab.....its very odd. When i let go and the gear engages it goes away. It only happens then. Almost sounds like the transfer case wine but a lil lower pitched. I dont think its the t case tho. Any ideas?
HELP.....

 

If you take a short video (safely while driving of course) we can probably be of better help. =)

 

If i I had a vid camera....ill try to borrow one from a friend.....anyone else have any idea wheat the noise may be.

 

t case. will prolly get worse

 

i bet its your flywheel..

 

what reason tho? I have exedy stage 2.

 

Yeah, the only thing I can guess off the top of my head would be the transfer case. You are downshifting and as soon as the clutch engages it makes the noise. That alone eliminates motor issues. It has to be the transfer case, could be flywheel, but I highly doubt it. Or it could be your syncros. I also would be of better help if I seen a safe video of this noise. Also if you could have someone record you driving by, downshifting and seeing how the noise sounds from outside the car.

 

Theres your answer.

 

Alot of people have this problem... dont downshift at so high of a speed and it will help but for some reason i know alot of people that have heard this.... i could be time to change your t-case fluids

edit.... my old s-2000 did it no matter what you did... i thought i was getting pulled over everytime! it sounds like you are getting pulled over for just a split second and it scares ya!

 

i just changed my tcase fluids like 12,000 miles ago....at it didn happen tday....weird....

 

Could be the t-case like everyone say, base on the whining sound. Cant hurt to change fluids again.

 

Triple check your TC fluid level. When I first filled my TC after changing it, I filled it until fluid was coming out 3 times. Every time i rechecked it I needed to add more. I think its an ACD thing.

 

change again 12k i wouldnt go past 15k so your basicaly there
