I agree 1 year is too early but I have read Toyota w/s leaves a lot to be desired . My 2007 shifts so much better with amsoil fluid in the transaxle.

My 2007 has only ever had Toyota WS in it, and it shifts brilliantly at 166,000 Kms. Mind you, I think the Japanese NCP95 with the AHPNK suffix has a different transmission for the AWD, but I just don't know how different.

Today, Toyota told me that they recommend an AT drain every 50K Kms. That's only 31,000 miles or so, which seems a pretty short interval to me. But at least your ATF should be clean.
