Okay so my transmission has always made this funny whining noise since I got it. I figured it was the throwout bearing and I would replace it eventually. So I rebuilt my engine and FORGOT to replace it.

Anyways here are my symptoms:
- Notchy shifting
- Transmission whines while I accelerate (I can hear the pitch change) and when my clutch is NOT depressed.
- As of yesterday I cannot shift without rev matching. Sometimes I can shift okay, I have to push like hell to get it in, but not enough that I feel confident enough to drive it.

So...
Does that mean that my throwout bearing is gone?
Does that mean that my transmission is gone?
Do you need more information to make a diagnosis

throwout bearing is only used when clutch is depressed. maybe you have air in the hydrualic system, also change the gear oil.

YearsOfDecay

Change the Gear oli/ check to see that its full..

Throwout bearing isn't gonna do that

Blead the clutch to make sure its working properly...

All else fails... WWW.drivetrain.com has tranny rebuild kits....

Also my transmission shifts fine when the engine is not on, if that makes any difference.

Same PROBLEM! I was told it was my throw-out bearing. When I idle, without the clutch depressed there is a whining or whirring noise that goes away when the clutch pedal is applied. Someone recently told me however it was not my throw-out bearing at all, but the transmission seal or ring or something. I would love to fix this because I know it is only going to get worse with time. If anyone can clear this up and give me a general idea of how hard it is to fix I would be very grateful!

Fritz have you checked your tranny fluid? Me and Nixxon will be checking his shortly.

ok, just to clear this up, if your throw out bearing is bad it will make noise when the pedal is applied. if there is noise when clutch is out and goes away when clutch is in, then it is a tranny problem.

Sounds like an output bearing problem I had with my FD. Exactly like it actually. you need a rebuild. Try some fresh transmission fluid anyway, it fixed the problem temporarily on my FD.

clutch hydraulics/ not disengaging all the way

Yea i have this same problem, so i decided to drop the tranny and put all new pressure plate, clutch, t/o bearing, and pilot bearing. I did this and everyone said that it was my pilot bearing making the noise. Well i got everything back in and it still does it. The main shaft moves a little bit, where there pilot bearing is...and i know its not supose to move, so i guess its gota be one of my main bearings...ohh well i hope mine lasts me the rest of the summer so i can drop a trubo II into it. But good luck on your problem man....could be one of your main bearings.

yozsi

the pilot shaft should have a lil' movement.

JasonL

So chances are if Nixxon's tranmission has fluid in it, it's the transmission that is the cause of the whining noise and the shifter problems?

If so we'll just swap in a spare we have kicking around.

How hard is it to replace the output bearing compared to the throw-out? Would I be better off just buying a used tranny for 200$ off someone on the forums? What problems should I be expecting down the road due to this output bearing issue? Crap the bad on my car seems to have gone to worse.

If everything in your transmission is good, and you can do the the wrok, chaning the output shaft bearing would be easier.

If you were to take it to a shop, you may as well have the whole ting rebuilt, which would be more than $200.

ROTILLA

If you are having to rev match to get it into gear, get a swapp to put in. Or you will have to have it rebuilt( bearings, syncros, seals, small parts kit) and that in itself is not expensive(@$175.00) the labor to do it is. Just swapp it as Jason said.
It will be much less of a headache if you do.

The throwout bearing is only used when the clutch pedal is depressed. So normally, noise caused by the throwout bearing is only obvious when it is under pressure (you have pressed the clutch).

The constant whine under use and accelleration is most likely the input shaft bearing, or cluster shaft bearings. Pretty common now that these transmissions are getting old. Synthetic fluid will definitly help a little, but the only real cure is a transmission rebuild. It may run for another 50K like this...mine did. Of course, then the cluster shaft broke on the highway, which was not fun (it was low on oil, must have lost a seal just after I got on the highway).

Hollywood56

the whining noise in a tranny is usually low fluid, input shaft bearing, output shaft bearing.Is your tranny noticably quieter in 4th gear? You will most likely need a rebuild.

DEZERTE

What was the result of it breaking?

SureShot

When you loose the input gear or the countershaft, you're left with only 4th.

A horrid grinding noise, and the car wouldn't move under it's own power. I didn't try 4th gear though...

Fritz_X

My car is awesome in fourth, others it is a little raspy . I guess I am going to need a rebuild I will wait however and get new redline fluid. Thanks for all the input guys, so which is it most likely the input or output bearing?

--Fritz

THANKS FOR ALL THE HELP!!

Hollywood56

Then its your input and output shafts on the tranny.Just rebuild it.Thats how you know that a those two components are bad,( a good and quieter 4th gear).Good luck with the rebuild fritz.Oh and just put new input and output shafter bearings in just to be safe.

polyfc

i have the same problem with mine. it's probably the main bearing(think that's what it's called) the one that keeps the input shaft in line. but depending on how bad the whirring is you should still have a while left on it. depending how you drive it of course.

ok guys from what i can tel i have the same problem as nixxon here and I guess my tranny is just bad. Now I am driving across country from Oregon and will be in fifth for most of the way so you guys think I should be fine since fourth its the nice gear? And how hard is it really swap out the input and output shaft bearings once the tranny is out?

JasonL

Swapped out transmissions on NIxxons car, it's fixed for now.

Starts making a good whine now though.
