98 civic ex 170k.
1st 2nd 3rd gear theres a nasty rattle/chatter coming from the transmission while in gear. If i press in the clutch while rolling down the road the noise has no rattle but is a wicked bearing whine. If while still rolling i let the clutch out in neutral its gone, put it back in gear with the clutch still down and the whining comes back.
Is this a throwout bearing? I saw input shaft bearing mentioned a lot on here but seeing as its the low gears only it would be the bearing on the clutch side right?
Anybody have any guesses?

 

one of the internal transmission bearings most likely. a throwout bearing would make noise when you press down on the pedal.

 

I would agree it is a internal bearing that is going in the transmission... usually if your ISB goes so does the countershaft bearings... about 100 dollars in OEM bearings at Honda... I just did some in a trans not too long ago
