My 5mt has been making some noise for quite a while now. The tone of the whine is consistent with my speed and is louder under load. When I decelerate it makes kind of like a flutter.
Not only that but shifting into 4th and 5th grind when the trans is warm (about 10 mins of daily driving).
I've been told it could be an input bearing making the noise and it could have stemmed from an improperly installed aftermarket clutch, but of course I wont know until I eventually open it up I'm not looking forward to the potential $2000 for a rebuild though...
And i just wanted to throw this out there, this is my first ever post to any forum ever.
