6-Speed Noise

Have an 06 trd off road 4x4 with 6-speed. The tranny is really noisy in nutral. Have brought it to the dealer 3 times. They had someone from toyota look at it today said that the noise is normal,it is like a howling noise but when the clutch is engaged the noise goesa away. Is this normal?

 

Welcome to owning a 6spd I think just about everyone's squeels. Its a defective throwout bearing.

Just do a search on "throwout bearing" you will a lot of posts. In my opinion its nothing to worry about and just kind of annoying. I have driven cars before with squeaky throwout bearings and never had them fail on me. but see what the dealer wants to do. I have never been one of those "the sky is falling" people when I hear a tiny little noise coming from my vehicle. I guess that comes from working on cars over the years and knowing what sounds I need to worry about.

 

Hard to know from your description whether the noise is the chirping noise or squealing noise referenced by macgyver.
Although I am not sure what you mean by a "howling" noise, and it does not sound like the same noise that has been attempted to be described in a thread I started in 4 cylinder forum called "Poll: Diesel like noise clutch determinative", the sound in mine (5 speed) goes away when the clutch pedal is pushed down. Again, I would not describe mine as a "howling sound" or even loud; but, everyone has their own interpretation of a sound.

 

yeap ,TB

 

No it is not a chirp or squealing. More like a grinding noise, i was told by the FTS that the sound is a charcteristic of that vehicle.It was not there when it was new. Past few months it has been noisy. Had the 4-speed and the 5-speed never a problem. i guess i should have got the auto?

 

Does it sounds like gears turning?

Mine will do that occassionally at idle and when I turn the truck off.

It might be something to do with the toyota 6spd transmissions. My buddy's supra makes the some noise when his idles and when he turns it off.

 

Maybe you could say gears turning sound, but really loud not just sometimes but when ever it is not in gear. That is normal?

 

I'm pretty sure I know what noise you are talking about. Like the someone mentioned, does it sound like a big rig idling? sort of a rattle/grinding/"geary" noise? I think its just loud gears. Mine does the same thing. But it's nothing compared to my buddy's subaru WRX that has a straight cut gears

 

No this is loud really loud going in a drive thru have to keep the clutch pedal down so you can hear. Just hard for me to belive thats normal?!

 

Mine makes that noise too but it's not so loud that you can't hear. It is noticable but nothing major.

 

Yeah, my makes a sound that goes away when you push down on the clutch pedal, bu most of the time you really have to listen for it. In other words, it is not that loud.

 

Mine does that too. I have only had it since December 2009, noticed it shortly after purchasing. Mine has 44K on it. It is not a chirp like many have described a throw out bearing failure. At first I thought I was hearing the power steering pump, but it goes away with clutch pressed down hard. Light pressure on clutch has no effect.

Local Toyota specialist mentioned it while on a test drive with me. He's not sure if it's normal or not, he does not see many six speed trucks. The dealer admits that there is a noise but says it's normal, and specifically said it is not a bearing type noise. Not sure what to to, it will be out of powertrain warranty soon. Planning a road trip soon, will see if it gets any louder.

Very happy with the truck otherwise, it drives great.
