Hello all,

I bought a new corolla 2009, automatic transmission (Not Robotic!)
From the first day, when shifting from first to second gear the car makes an unnatural noise, like a whistle or a whine.
(during shifting and sometimes a little bit before).
It only happenes in the transition from first to second. It does not depend on the RPM at the moment.
When the engine is cold, in the morning, the sound is still there, but weaker, when the engine warms up,
the sound keeps appearing for the rest of the day. (I live in a country with a hot climate)

I have been told, 2009 model has the same transmission just as previous models, is it true? or there have been some changes in it?

Has anyone else experienced this phenomenon with his car?
If you have, do you know of any solution for that?

Is it just my car? or it's something common?
Are there other common problems related with this model?

Thank you

One more question
Is the transmission in the corolla 2009 the exact same transmission system in previous models? (such as 2007,2006 which were without this phenomenon)
