2011 Chevrolet Traverse LS 3.6L V6 automatic transmission 199000km
I recently changed my transmission fluid with Mobil 1 dexron vi ATF. Should I drain and refill with AC Delco dexron vi (OEM)?
Does the brand matter or is it more the "fluid type" (dex vi) that matters?
I'd appreciate your help.
The Dexron VI formulation is defined and licensed by General Motors. Any good brand is fine.
