My buddy has a b16 swap in his CRX and his tranny has been whining especially in 1st. It also sounds like the throwout bearing is whining badly with the car in nuetral AND OUT OF GEAR with the clutch released, you push the clutch sound is gone. I've been telling him that thing sounds ruff for about 3 weeks and needed some fluid and finally today I checked it for his dumbass because he did'nt know how without a dipstick lol. It had probably less then a qt in it. In my oil pan you could see the pan in the middle but it did'nt have no shavings at all just very lil fluid.
We looked for redline MTF but could'nt find it so we used mobile1 synthectic 10w 30 motor oil. The car was driven 30 miles and now he scaried to drive it anymore because of the whining.

Any thoughts? maybe some better fluid could help him.

 

Yes, it's the Main Input Shaft Bearing, it's about a $20 part from Honda.

 

thats the throwout bearing correct?

How long can they run making that noise.

Would that automatically require a new clutch has well.

No its not the throw out bearing. El vap is right, the input shaft bearing is bad. This is <U>inside the transmission</U> Throwout bearing make noise when you push the clutch pedal down. I have also seen clutch discs with loose springs make the noise you are desribing but that is unlikely.

 

I always thought the throwout bearing made noise while the clutch is released and in nuetral and this is exactly when the car does it the worst. When you push the clutch in its quiet.

 

Also if its the input shaft bearing is it safe for him to drive or will it tear up his tranny?

 

It will tear up the tranny and leak oil past the seal eventually. The throwout bearing is what releases the clutch. It does not "work" until you press the clutch. With the pedal depressed, the gears do not spin anymore and the noise goes away. Pedal released engages the clutch and makes the gears spin and thus the bearing makes noise. So many people get this mixed up.

 

So should he stop driving it asap?

How hard are they to change?

What kinda fluid will it cause it to leak, MTF correct?

 

If he plans on trying to repair the tranny, it should not be driven anymore. Many people just get another one rather then take it apart for repairs. Its not a job you will want to tackle if you are not mechanically inclined. They usually have to be pretty bad to leak the oil out, but yeah whatever fluid you guys put in there could get past the seal.

 

my friend drove for months on a tranny with a bad input shaft bearing he even comuted to work with it. after so long he finaly got a new tranny and when i riped the old one apart there was metal shavings everywhere your better off getting a new tranny then trying to rebuild that one.

 

Thier was no shavings in his MTF at all but it was only a qt if that.

 

also you need to drain the fluid out again because Synthetic oil is horrible for a tranny I would drain it ASAP and use Honda fluid!
