STUPID tranny whine

[PRADOgy]

So i pick up a coupe.. stocker than a mofo..
as im driving in im in gear # 2 and i let off the gas and coast in gear..
a verry disturbing wind as if there is no gear oil in the tranny.. im like oh shit its gona catch fire if i dont fix it..
i since i was tooo busy i took it to EZ lube to get the gear oil changed.. and diff while im at it.. and fuck the problem is still there.. its in 1st 2nd and barley in 3rd.. but gear # 4/5 are good..

what is it?

[nevaland9]

mine does the same thing and has been for the past 3+ months, no fire. If someone could tell me what that sound is tho that would be sick.

[Kougeki]

Maybe it's the bearings.
I took mine apart and one of the bearings was messed up,
i changed them to be safe.

[916S14]

Change your throwout bearing, i had the same problem and that fixed it. Well does it make noice when you're idling? and goes away when you press the clutch in? Also i had my corolla wine just like that and i though it was the tranny but it was really the diff, i was confused because my car was completely stripped. If you're sure its the tranny change the bearings like the man on top said. Good luck

[SDS13COUPE]

Replace your pilot bushing. That's what supports the input shaft of the tranny. Once it's fucked you'll get play causing horrible noise. My friend's was like that after he did the auto to manual swap. Kept the auto bushing and then the noise came. So I replaced it and it was a done deal.

[lovely240]

when i first got my 240 it had a really loud fan noise, it was the wheel bearing, i got one off another car at a salvage yard and the fan noise went away...

Not again, :bash: . This is the eleventy billionth thread on tranny noises and on every one if them all the idiots point to the throwout bearing and pilot bearings when they don't even understand when they are moving. So AGAIN I will explain it. The throwout bearing IS NOT SPINNING untill you push the clutch pedal. If the throwout bearing is touching the clutch wothout any pressure on the pedal then your clutch pedal is adjusted wrong, PERIOD. The pilot bushing is ONLY spinning when your foot is on the clutch pedal and the trans is in gear. The rest of the time the input shaft is turning with the flywheel. Don't get all pissy if you ARE one of the idiots who automatically points to the throwout bearing or pilot bushing EVERY time, I don't blame you for not knowing but I do blame you for thinking that you do. Anyways now to be constructive. The noise is in the transmission itself. What tells me that is the fact that it only makes the noise in certain gears, under load. NOTHING outside the trans can do that.

[LA_phantom_240]

Hmm... I get a small amount of whine from my tranny in the first three gears as well. Kinda like how fords do. Some of you know what I'm talking about here.

[The Riot Hero]

pilot bearing, replace it or you will ruin the transmission.

[smelly240]

if its when u let off the gas only - it could be the diff... unless its really only in 2nd gear.

either way - you should check the diff. Pilot bushings go often as well.

[DALAZ_68]

damn main shift linkage ?? gear #2 might be giving out?

[stinky_180]

if its when u let off the gas only - it could be the diff... unless its really only in 2nd gear.

i haev the same whine/wind noise as the op... i swapped out to a VLSD and the noise is still there, so that cancels out the diff.

at first i thought it was the driveshaft but im now leaning towards the actual transmission.

Your statement is entirely wrong and it makes you look like a complete idiot. The hydraulic clutch setup keeps minimal pressure on the system at all times, this is why the TOB has bearings and is able to spin. You cannot completely disengage the TOB from the PP fingers because there is no spring to pull it completely back. If you were to pull your Slave cylinder off the transmission, without pressing the clutch pedal the rod will come out of the slave cylinder from the static pressure on the system. What do you think happens when it's installed on the transmission pushing on the TOB pivot arm? Misadujsted clutch pedals don't allow you to disengage/engage the clutch completely to put the tranny in gear. There is no over adjusting it, all it does is raise the hieght of the clutch pedal for disengagement or engagement the more you adjust it. When it is adjusted right, the TOB should be hitting the PP fingers(hence the free spinning bearing design), this is how the hydraulic system works. The pilot bushing doesn't spin at all. It's there for the Input shaft to spin on, it acts like a bearing because of the material it's made out of.

You are trying to tell ME about trans noises!!!??? You are a fucking super noob! I doubt that you have ever even removed any trans from any car. I do this shit for a LIVING boy, don't fuck with me. OK now I am going to pick your pathetic attempt at arguing apart.
1: If your foot is not on the clutch then there is NO pressure at all in the system. There are no check valves in ANY hydraulic clutch system that I have ever seen, and I have been working as a mechanic for 5 years.
2: The TOB has very little pressure on it in the rest position, so it's natural tendency is to vibrate away from the clutch assy. Also the spring that holds the clutch fork to the pivot ball has a mild retracting affect.
3: If your clutch pedal is misadjusted then it will hold tension on the master cylinder piston and keep a small amount of pressure in the system. This is not proper adjustment. Proper clutch pedal adjustment will leave you about 1/2" of freeplay at the pedal. So if YOUR slave cylinder piston pops out when you take it off the trans your pedal is probably misadjusted.
4: As I stated previously, the pilot bushing turns only when the car is in gear with your foot on the clutch, engine is spinning but the input shaft is not. The pilot bushing itself is actually pressed into the flywheel, so obviously it can't turn in the crankshaft. So to clarify, the input shaft is only turning within the pilot bushing when the car is in gear with the clutch pedal depressed.

[opponheimer]

everything racepar has said is correct... its the bearings. any imbalance in the driveshaft could cause bearing failure

[UNITEDMASTER]

Hello, not to get into this lil shootin match here, but as far as I knew the pilot bushing spins as long as the motor is runing ( because it is pressed into the crank shaft).SI or NO, Im not here to argue ,my car works just fine!!! THANKS

Yes the pilot bushing spins with the crank, but unless the input shaft is stopped it has very little movement in relation to the input shaft. So unless you are in gear with the clutch pedal depressed it will not make noise.

[murda-c]

btw as a rule of thumb, whine usually = gear, and grumble or growl = bearings.

check to see if you get it in fourth and fifth. if you don't get it in fourth but get it in fifth, it might be your inputshaft/countershaft gear.

or that's what a 20 day course at lincoln tech told me about manual trans, so this should all be taken with a grain of salt.

[harangatang]

The pilot bushing is ONLY spinning when your foot is on the clutch pedal and the trans is in gear. The rest of the time the input shaft is turning with the flywheel.

Not true.
The tranny does not have to be in gear for this to happen.. Trust me. I just fixed this very problem.
Even in neutral, the crank is still spinning. So it doesnt matter if the tranny is in gear or not. My car would make the same noises in neutral with the clutch in that it would make while in gear with the clutch pushed in.

I would just take it to a tranny shop. After doing a throwout bearing once in the garage.. its not worth the time and trouble to me. I paid a guy $150 to replace the pilot bushing for me. That was probably the most well spent $150 on my car so far..

Let me ask you a question. Are you and ASE certified trans and driveline specialist with over 5 years of experience? No you are not. The pilot bushing allows the input shaft to spin inside the flywheel. The only time that the input shaft is spinning at a significantly different speed is when you are in gear with the clutch pedal depressed. If your pilot bushing is bad it will not allow ANY slippage between the input shaft and flywheel unless the aforementioned conditions are met.

you can argue with me all you want.. I dont give a shit.
Im just saying, my car made the same noises in neutral that it did while in gear... So, whatever.
And why do ppl always have to pull the same old bullshit " Im ase certified blah blah blah"... who fuckn' cares.

[eli_eli]

hey guys, i was actually gonna start a similar thread, i just bought a car with a nismo 2way lsd.. has nismo super coppermix clutch and flywheel, it took my a while completing the install and i just recently started driving it, but it does have a similar problem, i have only noticed it majorly in 4th gear, it might be doing the same in 3rd and 2nd but obviously not as bad, i cant really tell since the car a bit laud so it is hard to distinguish the sound, but anyway in 4th gear it starts to do the whining sound "only once i let go of the throttle pedal, and goes away once i press it again, it is really laud and constant if the gas pedal is not pressed and goes away whether i press the gas pedal or clutch in", if anyone knows the exact problem plz help and save me some mulah plz lol, thx eli

Look man I do this for a LIVING! That is the point. I have far more knowledge, training, and experience than you do. I have diagnosed HUNDREDS of driveline noises successfully, so YOU can argue with ME as much as you want...So, whatever.

[stinky_180]

haters take it personally.

like i mentioned above, i feel that this whining/wind noise is from the actual transmission itself, like the gearbox or whatever the hell you call it.

hey racepar, how much would it cost to fix this problem? do you do rebuilds by any chance?

[Lurkable]

With my car, I experience a loud whirring noise in 1st, 2nd, 3rd, and 4th gear (might be 5th too, hard to tell though at high speed with an exhaust leak!). It makes noise ONLY when I am coasting in these gears (no gas, no foot on clutch pedal). If I have read everything correctly, I am going to assume it's probably my throwout bearing - correct?

Of course I'm going to take it to a transmission shop, but I have so little free time during which my car can be looked at/worked on. I'd like to give them an idea what it might be if possible.

Yes, I also care that the person giving me advice is reliably endorsed. :)

Looks like its Getrag time!

Guys.. thanks for the info..

the noise sounds like an empty cardboard box on the floor and you pushing it around..

yeah its no on throttle just on decel and in gear.. when i hit the clutch boom problem gone.. yes it does make the noise in neutral as well.. its just not loud .. but i can hear it.. i press the clutch in and gone.. it is in all gears.. 1,2 are lound and it gets quiter 3,4,5

yea i have that sound too. my only guess is the gear's bearing... it is a 17yr old tranny.

My guess would be bearings then from what you said.

can anyone help me still plz lol, i have read this thread over and over, but what a few ppl said and fought over kind doesnt make sense, if anyone can plz be a bit more explainatory, thx

[redline racer510]

Yea I have the problem too someone told me it was the throw out bearing??

[98koukile]

My tranny guy said deal with it, you drive a 240 not a maserati bitch

[Dream240]

I know this thread is a little old and this may be redundant info to most guys on this thread, but I felt that I should help out this dianosis since there's alot of guys that complain about this problem and no one ever posts up complete fixes.

Honestly tranny noises are very hard distinguish from engine and other driveline noises in 240s....they make so many noises just running as-is.

The wirring, grinding noise most of you guys complain about while in gear is coming from the actual tranny.

In most cases you have excessive vibration being transferred through a bad tranny mount (located just below where your hand sits while shifting), unbalanced driveshaft, unbalanced flyhweel/clutch setup, or faulty main input shaft bearing. These vibrations travel straight through the tranny shafts and right into the shifter and your hand. Ever notice how the noise gets LOUDER when your holding the shifter? Also aftermarket shift knobs really amplify the noise and vibration, especially the resin ones.

The throw out bearing and pilot bushing are rarely the culprits of constant noises coming from in-gear decelleration. Throw out bearings usually make noise when engaging into gear, whether it's upon initial pedal pressure or as you release the pedal to engage the gear. that's usually when a bad T/O bearing will rear it's ugly head. And it will most likely squeal like a stuck pig.

As for the pilot bushing, all it's meant to do is keep the input shaft centered in the crank while the engine is running. These usually go bad by improper installation, or not enough lubrication (they're brass afterall). They WILL make wirring or chirping noises while in gear, accelerating, decellerating, idling, revving in neutral, but you should be able to distinctly locate the noise right from the bellhousing-to-engine point. Using a stethoscope helps ALOT.

Also just an FYI, upgrading to a short shifter, aluminum flywheel, stronger clutch, lighter driveshaft, or stiffer diff or subframe bushings will amplify this problem. There's no way around it. And using different fluids generally does not quiet down the internal noises, just make shifting easier mostly.

In most cases, it's just something to get used to.

Hope this helps.

[cserrano86]

Ok, I have the same noise coming from my tranny but that is not the worst of my problems now. I'm having trouble with Gears locking me out. Every once in a while my 2nd, 4th, and reverse will not go into gear while i have no problem with my 1st, 3rd, or 5th. All i have to do for the gearbox to let me put it into gear is give it some gas while rolling and the tranny aligns itself. Today however my 5th gear started giving me shit. I was driving on the freeway and the gear locked in. I had to pretty much force it out of there. so now whenever it put it into 5th it locks in and i have to pull it out again. Has anyone ever heard of this? Please help me out. Thanks...

[Dream240]

Yeah, It's called a failing transmission. Your gear synchros are just about done.

Find a used one locally or on eBay and get it swapped out.

[Risu2112]

...or faulty main input shaft bearing...

QFT,

My tranny had this exact problem a few years back, opened it up replaced said bearing, while I was in there did some work on the sync's. Completely fixed the problem. Didn't even occur to me based on the symptoms that it could have been anything else! <3

[ilike2drive21]

so my car makes the screeching noise between 2500-3000rpms i thinking its the pilot bushing since someone stated it could be lack of lube and what not. Can i get a second opinion preferably from someone who has much experience on transmissions

yea i've owned 2 s13's that had bad input shaft bearings as well........ seems kinda common to me anyways lol

Just read through this thread, and do some searching on here for other threads on the same topic. There's at least 3 other threads that offer alot of info on where to start.

Unfortunately you're gonna have to get your hands dirty before you find the problem. Most drivetrain noises require some under the car inspections. And we obviously can't do that for you. Just find the helpful threads, print them out and get to work zeroing in on your problem!!

Good luck.
