when you shift from first to second it makes a grinding noise from the transmission...and when it sits at idle it also makes a grinding noise but if you push in the clutch the noise stops. anybody know what's wrong with my crx?

 

throwout bearing is toast.

 

it aint the throwout bearing,its the input bearing or broken gears

i'll agree that its probably the input shaft bearing. 2 trannys did that on me before they broke. and i had brand new throw out bearing (release bearing).

i'm not saying it can't be the release bearing, but IMO its probably the input shaft bearing.

 

In plain English

input shaft bearing .. the noise is on all the time.
throw out bearing .. when the clutch pedal is pressed it goes away

Its likely ur throwout bearing

really? cause when you press your clutch petal, you are in turn disconnecting your transmission from your motor. so why would you hear the input shaft bearing if the transmission is not turning? it very well could be the throw out bearing, but you can't tell people that the problem they have is definately one thing when it could be another. So this guy has either a throw out bearing problem or a bad input shaft bearing. now its up to him to find out which one.

 

i think im just going to throw in a new tranny. could i put a hydro tranny with my d15b6 block? or do i need a cable tranny?

 

just use cable

k thanks for the info guys.

 

I am going through the exact same thing. But decided to drive like that anyway, and the clutch gave out on me. The clutch wont engage like normal, it engages like a race clutch.... like a 2 puck!!! So im just getting a new tranny along with new clutch kit. I would recomend you not drive it as much, or at all.
manny

 

all of the people who have came to me had broken spider gears or a bad input bearing. it was never the throwout bearing

 

k...thanks for the input...im now looking for an si cable tranny. let me know if you guys got one. i would prefer me picking it up so somewhere around wisconsin, minnesota and the northern illinois area.

 

my buddy had the same problem with his 93 sonoma......check the tranny fluid.....his did that and he had no fluid at all....

 

For everyone saying it is the throwout bearing causing the sound yet he says it goes away when the clutch pedal is pressed down needs to read more books because the throwout bearing is only engauged when you press the pedal down so it can only make noise when the pedal is pressed in.

When the car is in neutral either physically in neutral or just with the pedal pressed down the transmission does not spin at all because it is disconnected from the engine because there is no pressure on the clutch. So no noise in neutral means nothing from the transmission.

Something like this will require removal of the transmission to inspect the area down there to see what is really up. I would suspect something from the clutch/pressure plate area is fucked up.

you poor poor son of a bitch, having to listen to all this bullshit.
The answer is up there ^ .....somewhere...

this is half correct. When the clutch pedal is pressed down, the tranismission input shaft will not spin, as long as the car is stopped and/or not in gear. When the clutch pedal is up, the transmission input shafts spins whenever the car is running, no matter what you do with the shifter(even in neutral), no matter if the car is moving or not. And I really do know what I'm talking about here.

 

ok gotta clarify for those who are new to transmissions..

it sounds irrelevant, but not really.

lots of times noises/grinding seems to make perfect sense that it's one thing, but then when you learn a bit you realize is could be ONE OF TWO things, and then you have a specific test to narrow it down. That's pretty much what's going on here.

ORIGINAL POSTER:

Read every single thing you can about transmission in the next few days and you'll be able to narrow it down to the exact thing it is. And you'll come away with some knowledge.

PLEASE COME BACK TO THIS THREAD AND POST THE FIX!! PEOPLE DO NOT DO THAT OFTEN ENOUGH!!

EDIT: you want to read about the following:

-throw out bearing (realease bearing)
-pressure plate (fingers)
-clutch disc
-flywheel
-pilot bearing
-input shaft bearing
-synchronizer (hub and sleeve)
-synchro ring (blocking ring)
-gears
-reverse idler gear
-output shaft bearing
-differential (pinion and side gears)

good luck

if i forgot anything, everyone please add on.

My tranny does the same thing in 4th gear. If I replace the clutch will it fix it?

usually 'grinding' caused by a failing clutch is most apparent when shifting into second after you wind up first gear. It can be noticable in other gears, but if it's apparent ONLY going into 4th gear, then it is most likely your 4th gear synchro ring.

Actually you are correct, not sure why I didn't think about it.

Also it should be stated that when the car is in neutral (pedal pressed in) and the vehicle is coasting that will still keep the output shaft spinning. So doing that is a good way to isolate problems sometimes.

yeah, vehicle coasting with shifter in neutral and clutch pedal pushed down will only allow the output shaft to spin.

vehicle coasting with shifter in gear and pedal pushed down will make the input shaft spin also.

something that seems to help it make sense to some people is for them to realize that the speedometer is geared off the output shaft. No speed registering (barring any malfunction from the speedometer gear), no output shaft movement. Wheels turning, ouput shaft movement, speedometer registering speed.

something even more interesting is when you think about transmissions seizing up. If an output shaft bearing seizes up, you're skidding till you stop. If it's the input shaft bearing only, you might be able to get it out of gear and stop without skidding(by locking up the brakes and then pulling it out of gear; locking up the brakes puts the weight of the vehicle on the brakes instead of on the gear itself). You're not moving once you're stopped, but in emergency situations, traction is always better.

EDIT: something to remember in an emergency..

and I'm done rambling now..

sorry..

 

hmm...dont really know whats up with my tranny yet because i was saying that if its fucked up then i'll just save up and get an si tranny but since i came back and read this i'll be taking the tranny apart this wednesday, take some pictures and post them back here. see if you guys know whats up with this.

 

i have a perfectly fine dx tranny if you want it..150 bucks yo..

post pics of the throw out bearing as soon as you get it freed up, then worry about the pics of the inside of the trans later on.
