Dark brown fluid is not a good sign.

The newer fluids can be interchanged with both T-iv or dex 3, but dex 3 and T-iv should not be interchanged.

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.
Either way I will still use this stuff to cover all the bases, both dex III and type IV:Valvoline.com > Products > MaxLife > Automatic Transmission Fluid MaxLife > MaxLife® DEX/MERC ATF
