clutch or transmission problems

[LJ851]

good deal. ill live with it till i do the engine swap. thanks for your help!

Are you familiar with how to double clutch ? It will make it easier to drive with a worn out syncro .

[Blaine0002]

Yes.

Would another transmission be the easiest solution?

Yes.

aite so i did the shift linkage today... it was pretty much a bitch till i dropped the transmission support. anyways the car shifts sooo amaaazing now, but still wont go into 2nd. only grinds.
What are my options?

Although true this is not accurate. While applying force to a TB the noise could subside.

No it couldn't. The throw out bearing is inert until force from the clutch pedal pushes it into the pressure plate. Unless it is severely mangled and destroyed, in which case the OP probably wouldn't be able to get it into gear at all.

While the clutch is depressed and the TB has little to no grease on it, it will make a nasty noise.

This is exactly what I was saying above, contrary to the first part of your post. The noise is heard with the clutch pedal in a full UP position.

This recently happend to my friends e30 when we replaced his clutch and pressure plate and TB. friend forgot to grease the TB and the noise would only happen when the clutch wasn't engaged. Took it apart to find the TB all torn up replaced and GREASED the new TB... no more noise :)

Although this is possible it is much less likely than Ryanns diag. For one you havent been able to buy a metal T/O bearing in a Long time. You arent greasing plastic ones are you? Also the OP relates a whirring noise (input bearing) as opposed to a rattling "nasty" noise that a trashed T/O bearing would make.

Seems like the OP is describing input shaft bearing noise to me. The noise GOES AWAY when he depresses the clutch pedal. When you depress the clutch pedal it disconnects the input shaft from the flywheel allowing it to stop spinning. If the noise were to appear while depressing the clutch pedal one could assume a noisy throw out bearing as it is having to spin while applying force to the pressure plate springs.

Now im depressed. ha. Ryanns observations are correct, act accordingly.

oh i see.. i thought we were having an unthaw moment. :giggle:
thanks lol

Now im depressed. ha. Ryanns observations are correct, act accordingly.

[Ryann]

lol

Definition as used above: depress- to push something down into a lower position i.e. "depress the lever"

Anyway, insert "press" in place of depress if you like.

Pilot bearing issues can cause the shifting problems you're experiencing because a bad one can be grabby on the input shaft. If it is, the input shaft won't slow down quickly enough while your clutch pedal is depressed during a shift. Based on your noise issues though I'd say this isn't the case for you because like a throw out bearing it'd be more noisy with the pedal depressed. Perhaps your 1st and 2nd gear synchros are getting a little worn and need some new quality fluid like Redline MTL. In fact, maybe your tranny is low on fluid period. This would cause both bearing noise and poor synchro performance.

the noise goes away when i PRESS the clutch (not depress)

is the throw out bearing a major issue and should i replace it asap?

once i get the shift linkage replaced ill let you know how it shifts.
thanks for the quick replies.

Yes get it out and replace it ASAP. Dont forget to grease up the new bearing or else you will get the same type of noise and the bearing will go out again fast.

[Gubernaculum]

My throw out bearing was making noise for 6 years (I don't drive much) before getting progressively worse (hard to get into gear) over a few weeks then finally giving out at an inopportune time.

You will need to pull the tranny to change out the bearing. While it is out is the best time to do the shift linkage.
