Whining noise?

Haha it know it sounds crazy but I did not go under the truck, just stepped out.

Anyway took it to the dealer, a technician looked at it and want me to bring it back next week.
I test drove a 2014 TRD sport and as a matter of fact it sounds the same.

 

i had that as a ringtone on my phone! everyone hated it.

 

Update:
Dealer said that I have a bad torque converter.

 

My 2011 Taco has that whine at 45K last month .... I brought it to the dealer, it was the Pulley Idler bearing they said...repaired covered by warranty..but you have to tell them it is covered by the warranty ( Power Train up to 60 K ).....

 

Yes it is covered under power train warranty. In my case the sound is coming from the transmission. I just can't get why would it fail with only about 35k and as I mentioned above I never towed anything or abused it.
I'm pretty disappointed with Toyota quality.

 

Oh yes, my 2011 Taco too..... Fuel pump failure at 42K and Pulley Idler bearing at 45K........ my 2000 Nissan Frontier was worse.... all brakes worn out at 32K with rotors need to be changed ( city driving 100% of the time ), low pressure aircon hose(tube ) at 38K, unsolvable engine failure at 42K which later turned out to be the On Board Computer discovered at 52K when the truck failed Smog test...... at 42K I already spent $3,000 for repairs and finally fully repaired when the OBD computer failed ....now this 2011 Taco, I'm now at 51K and afraid long driving as I do not know what will breakdown next...

 

6 speed.
No whine,just wine.

 

I would be careful fellas about Idling your truck in a closed space that carbon monoxide will get ya quick.

 

Id just tell people it's a supercharger
