Supercharger whine without the super charger

I have a 2010 Double cab shortbed that has developed a whine while gently accelerating or gunning it. It sounds like the transmission fluid is low. It doesn't whine in neutral revving the engine. I have taken it back to the dealer and they pulled it in and looked under the hood. It was right in front of an observation window and I never saw the tech crawl under the truck. They say that the fluid checks fine. They come up with a "can not duplicate" problem. So I ask the tech to go on a ride with me a he says he can hear something, but it would be difficult to pinpoint the problem. They note the problem on the invoice and say that they will check at next service. I am quickly loosing confidence in this service department. Has anyone heard anything like this? I don't want to kill a transmission on a truck that only has 7600 miles on it.

 

I have an 09 and I think I have a similar thing going on. But mine comes and goes. But like you I dont know what it is.

 

Is that even expectable? It’s a brand new truck still under warranty; I would call Toyota.

 

yea i have a similar problem except mine sound like theirs something with the alternator it sounds like a slight whistling sound when i rev it ?????
any body else experience this????

 

And now I don't know if I am imagining the transmission shifting oddly.

 

automatic or manual?

i have a b&m shifter and it makes a whine noise on first and second gear.

 

I wonder it its a pump?

 

I'm from Lexington, I'm guessing Jim Hudson? The Lexus dealership is extremely helpfull so you might want to take it there also.

 

It is the 5 speed automatic and Dick Dyer Toyota

 

Kill it and then tell them they should have checked it out better and now they have to replace it under warranty.

 

Oh, you should call Jim Hudson Toyota they deffinetly are nice there and I'm sure they will try and figure out what is wrong.

 

Ive heard a FORD do that during driving..


It was the power steering

 

Mine has a whine like that and it is the power steering pump.

 

I have a really bad whine with mine too. It seems to come from the passenger seat area...Oh wait, I think it might be my wife. Nevermind.

 

I have that too but mine is loud. I think its the Power steering pump.. Mine is starting to leak a little.

 

i have the same whine the more gas the louder it gets. I have a K&N CAI dont know if thats part of the problem mine sounds like its a TURBO TACO but dosnt seem to be causing any problems

 

I had this exact problem... dealer replaced the top idler bearing on the fan belt. 10000 miles on my 09. I don't hear to many others with this problem, must have been a bad bearing.

 

I have that same problem. huh I wonder if there is a TSB for that. It gets worse if I look at other women.

 

Hey Guys: I just changed out one of the idler pulleys on my 4.0 and it was making a wicked whine. All is well now except my pocketbok to the tune of $100.

 

Had this happen in another truck I owned. Alternator is about to go.
