can a bad input shaft bearing cause grinding of gears? because once in a blue moon my 3rd gear will grind then the next day i will wake up and rev it to 8grand and slam it into 3rd and it will be fine. my input shaft bearing is crap i can hear like woah.

 

the grinds tend to be much worse when trans fluid is fully warmed up and thinner. cold fluid seems to be enough sometimes to keep it from grinding. change the bearing you are ruining the transmission.

well, when they get bad enough it can cause grinding. I fixed a 97 civic one time that had gotten so bad it popped out of gear, grinded and was almost undrivable. it had about a quarter inch play in the shaft when I wiggled it

The bearing itself can grind, but it won't cause your gears to grind.

 

typically no.

I like that answer better, because I have experienced otherwise on two seperate occasions/vehicles.

 

Replace it. If that doesn't do the trick, it's your syncros.

 

bump for more opinoins

imo get a new tranny... i had a bad input shaft bearing in my dx trans all it did was howel/grind until i pressed the clutch in than it would go away

 

a new tranny for a 40 dollar bearing? youd have to go through the same labor anyway to put a new trans in.. come on get the bearing and throw it in..and no bad input shaft bearings cannot cause gears to grind

 

unsure form your post what u ment any way heres the dilemma i could get a b16 tranny for 400 pluss 100 for a buddy of mine to throw it in. or how much do u guys thknk it would be for a tranny shop to take mine out replace the bearing and syncro and bolt up a new clutch for?

 

sounds like syncro's
