Hello,
Gearbox in my s14 (SR20DET) started making a noise as if I would be shredding the synchros. It’s not such a loud/violent/high-pitched sound as when mishifting, but very similar.
The noise started at autumn, at first it was hardly noticeable and occurred rarely after revving past 4500rpm and lifting off. During the winter I kept the car in a garage (didn't touch it for 4months). Driving again at spring was a pain. The gearbox screeched when in gear 900-1300RPM and when lifting off past 3500rpm in neutral. Now putting a few hundred miles after taking it out of the garage it got somewhat better, the low rpm sound disappeared but when I rev past 4000rpm in gear it starts screeching and when I lift off (breaking with the engine) the noise gets a bit louder.
What can be causing this sound? Can it be the clutch(it started slipping a bit even before autumn)? Or can it be the synchros (yet the sound seems the same in 1st, 2nd and 3rd gears)?
(clutch, gearbox -stock; engine-almost stock)
