The manufacturer of the only automatic transmission used on the Aveo is Aisin, not GM. Their specifications (not GM, not Chevy) call for Dexron III for that particular transmission, the 81-40LE. That pertains to all Aveos from their inception and it hasn't changed since. GM can put the A/T fluid in a special GM bottle with their part number on it and call it whatever they want - but it's still Dexron III.
