Hate to bring up an old thread but I am experiencing some 'weirdness' with my 6MT. I noticed the whirring noise a while ago and didn't think anything of it. If I am driving and let off the throttle in 1st gear the sound will be apparent (with no stereo on).

Now lately I have noticed a weird noise sounding like the throw out bearing.

Car running (my neighbourhood is pretty quiet) open the drivers door. There is a noticeable whirring/buzzing. Push clutch in, sound is gone, release clutch, sound is back.

I came from Mazda Proteges and found this transmission to be extremely clunky, noisy. My Mazdaspeed Protege takes a beating at the race track and doesn't make a peep.

 

^ My car has those same symptoms. 2011 tc

 

With a little bit of digging throughout the forums this seems to be a "normal" noise.

thread: Also it is more apparent to me that the transmissions in these cars are just noisy in general. Lots of people track these cars (Scion encourages it) and if there is no exploding transmissions after tracking i'm sure we have nothing to worry about.

 

Yea and plus these engines are seriously noisy as well. Even the Edmunds review said it sounds "Diesely". I like it though, it sounds like my 2006 revving with a CAI.
This thread bummed me out at the beginning, but no one since 2011 said there tranny blew up. One said it was replaced but maybe he brown-nosed the dealer..
I drove a quiet loaner car (camry) when they did my tint. And I felt confused driving such a quiet car :p

 

Sounds like how the transmission acts depends on how you drive. My 6mt was fairly stiff and very notchy for the first 1k miles, but as soon as I hit 1k miles I did an oil change and started to have fun. Since then the notchyness went away, the whirr noise is still present, but the not going int 1st has went away. I slam a few gears on a daily basis. I am at 6k miles now, nothing has blown up yet haha.

 

Has anyone had issues with trannies in rs 7 and 8?

I'm pretty sure that the tranny is the exact same in all tc's. I have an 11 that I bought with 6 miles and now have over 55,000 (it's stick) and I have no problems here knock on wood. These transmissions are really good from what I've heard, but there is always the lemon and the ahole driver that will mess it up big time. Don't let the noise bother you it's just clunky. I'm pretty sure if the tranny in these cars were problematic I would have found the issues by now. I think the only people who have had issues were under 10,000 miles on the car so I wouldn't worry about it. At least it'll be covered under warranty lol

 

Stopped by my local dealer today and spoke to the service manager. He said the humming noise/whirr noise is the throw out bearing. Toyota changed the design of the throw out bearing which is why it is now noisey and it is normal. If however it does get louder then bring it in. He said they already dealt with putting a new one into a new tC and the sound came back.

 

Mine does this, never really thought about taking it in. Just thought it was normal because of what I hear in reverse, and I think (correct me if I'm wrong) reverse is first going backwards. 2012 tC

 

well, my car has had this whirring noise since i bought it, my current KM is 56,500km, it has gotten worse to the point that i now think i have either Grenaded the Throw out bearing or did something to the tranny, when driving it i am now getting more of a metal on metal sound than anything like a grinding that is dependant on the engine speed, and when pushing the clutch in it goes away but can hear a distinct clicking sound as if a bearing is screwed..... hmmmmm cars sitting at the dealer right now, lets see how this goes, also guys with this noise be weary(sp?) on this matter keep a close ear on your transmission. EDIT: Just got off the phone with my dealership, they are replacing the release bearing under warranty to possibly solve the problem from my car....... So ima suggest everyone goes and gets it done

 

Why? Has nothing to do with your transmission. I had my springs, intake and exhaust installed when they replaced pretty much my entire tranny.

 

The whirring noise I was told are the synchros. If you let it sit without the clutch depressed it does it.

 

I think that is the same thing happening with mine. I get a whirrr noise in neutral on idle. I am going into the dealer tomorrow and I will report back.

Also, the only way the dealer can void your warranty is if they prove the aftermarket parts installed caused the issue. So a TRD short throw won't create issues considering it is an added option that Toyota offers and they can install it. Intake and exhaust won't cause problems either since they're not tied into the trans. Springs aren't directly tied into the trans, however, if your CV joints were to fail and you're lowered on something other than TRD springs, then they can void the warranty as you changed the angle of the axle aka wearing out the joint.

 

Scion dealership drove my car and they are putting work order in.. it chatters a ton in reverse.

 

Update:

I had the car checked out at the dealer about the whirring noise in neutral on idle. The noise is not something the tech has heard before. The tech called into Toyota Service and they stated there is not a service bulletin posted about this issue or any possible procedures to remedy the noise. The service adviser called East coast Toyota Engineer, who will be present at my local dealer on the 21st of September. The engineer requested for me to bring in the car so he can inspect it himself.

So until then, I was told to just drive it. If the engineer does find anything, they will try to come up with a solution and possibly create a recall on it. I will keep this updated.

 

They're saying throw out bearing possibly, i have one on order will let you guys know on monday when i get the car back

 

That's what my dealer also suspects, but because it is not something they've heard of and there is no service bulletin, they're having someone with more knowledge come in.

 

Joy of being in canada we dont get the "technical people" we get trial and error

 

Nothing wrong with trial and error but if a throw out bearing doesn't fix it, they will change the trans. If that doesn't fix it, then money was thrown out the window.

 

Not for me lol, at least when its done i'll have a new powertrain
