I see, quite a lot of information there.
For your information, i got mine check in Anthony Smith in Coburg. The so called repair consultant has inform me the same thing that its normal. Later which i manage to obtain some advise to have a transmission oil change.
There is some issue here too as i was quoted between $200-$300 for a transmission oil change which they say they will change the filter pan, oil, etc and labor. Where else the other one only quoted me $60-$100 for transmission oil change. Do note that both quote are from different Toyota dealer.
Of course i opt for the cheaper one which i suspect they just do transmission oil change only when i find out later the noise still persisting.
But i gotten this advise too that to completely change your transmission oil you should at least do them twice as a normal change will only drain 40% of the transmission oil since there is still fluid trap in the transmission.
So my point is try get Trans Oil changed first completely. My car warranty just expired as i just done 67K on my car. If yours is still under warranty i would be much appreciate it if you can take further with Toyota on this matter and keep me update.
Note:- Mine only whines on/exceed 100KMh. Btw whats Diff means?
