What I have noticed in the last few times I have driven my car is that when down changing from say 4 to 3 or 3 to 2 I sometimes (not everytime) get a noise coming from the gearbox or clutch. once the clutch is fully engaged the noise is gone but whilst the GB is coming up to speed it makes a kind or a whine or a hoooting sound ????? any clues as to whats going on???????

 

does it do it when you drive off in first?

and is it and exedy twin disc? if so My car makes the same noise and was told its normal

 

havent noticed it in first gear only when down changing mostly 3-2. I havent changed the clutch in it so not too sure what is in it...... doesnt feel like anything after market.

 

damn.. then i'm no help. GL with finding out what the problem is

 

Figure out what clutching is in it...lay under the car, there will be a rubber plug on the bell housing of the trans. Pull the plug out and tell us what color the clutch is and what it looks like. My twin disc was noisy as hell

 

i have the same problem, but with mine the sound gets louder as i go faster... not the tc because i just had it rebuilt by shephard... i have a act clutch xtss .... i heard that it could be the input shaft bearing..

 

Possible...I'm runnin the same clutch as you evo8mr...I get a whine only in first gear...that's usually the only time it makes noise, the only way to find out if the input shaft bearing is going bad is to pull the trans

 

Yeah not that keen on pulling the gearbox. Maybe have to wait till the problem becomes more pronounced. Just like to know what it is that's all. It not easily repeated only happened once on the way home from work. But by the feeling i would say you sounds like a bearing.... Is there an input and output shaft bearing???? It's not in a single gear so it's got to be something that's constantly rotating

 

Will try to get under and have a look at the clutch also...
