I've recently bought a GTS25T and everytime I start the car, I can hear a constant chirping sound when the clutch is not pressed. As soon as I even touch the clutch pedal, the noise stops completely.
My mechanic has told me over the phone that it's either the throwout bearing ($800+ to fix) or the transmission (over a grand to fix).
However it's not a big sound at all, and doesn't seem like it could damage anything. It can't be the throwout bearing, because the characteristic of a worn throwout bearing is loud chirping when the clutch is pressed, not released.
So I've googled and googled, and this seems to be the most cost-effective solution, it makes sense but I just want some acknowledgement before I go and try this procedure:
"To fix the squeeling; chirping; or whirring sound that goes away as soon as you apply even the slightest pressure on the pedal. You need to replace the lubrication that has dried up at the point of the shift fork and pivot ball stud. The loss of lube has allowed it to dry up and the noise you hear is actually a frequency vibration and as soon as you put pressure on the pedal it dampens the frequency, and the noise disappears. To replace the lube do the following:
Get a can of disc brake wheel bearing grease and a small stiff brush, like an 'acid brush'
Pull the shift fork boot away from the bell housing
Push the shift fork forward, towards the front of the car. This will be difficult, but you can do it. It will probably look dry and rusty in the area of the contact of the ball stud
Now, while holding the fork forward, take the brush that has been loaded with a dab of grease, and smooth the grease around the area of the ball stud and shift fork dimple. Do this 2 or 3 times.
Replace your shift fork boot, if so equipped.
You will have eliminated the noise. As soon as you start up the engine, the noise will be gone."
What do you guys think?
