Upgrading From 07 To 13 Es350

[az john]

I'm considering an 07-13 upgrade and notice in the online specs maintenance is recommended 12 months or 10k miles. Is this a good idea? Problem with oil is the additives breakdown and this seems a bit long to wait.

Also specs say transmission has an auxiliary cooler. Have there been tranny problems since my 07?

Thanks

With synthetic oil 10k intervals are common. There should be no worries. I'm not aware of any transmission problems with the 2013-2014 ES.
