Toyota dealership told me noise was coming from the transmission but in my opinion it was coming from the engine.
ATF fluid was change several times in the last 3 years - May 2008, November 2008 (including the metal filter under the fluid tray), July 2010 and in October 2010 as well when a dealership mechanic removed the tray to examine it for debris. Everytime fluid was in good condition, no burning smell, good color, no metal debris on the bottom of the tray (Dealership mechanic confirmed it), it was perfect.
I have about 300,500 kms on it. I bought it when it had 234,000 kms 3 years ago.
Could it be water pump or steering wheel pump? Or timing belt? It's hard to tell exactly but I believe howling noise comes from the centre of the engine somewhere there.
