Looks excellent to me. The copper is high but that must have something to do with Toyota's because others have been much higher than your figure. I am no expert but it looks like you could go even longer before a change say 75,000. Got to love Toyotas but maybe it is the Racor filter?

Was the ATF drained at the time of sample? Was filter changed?
