I don't think Dexron III is made since GM won't license the name. Dex/Marc is supposed to be the one to use. I would NOT use Dex VI. I put Dex/Merc in mine.

From Wikipedia:
"The fluid specification for Dexron-VI was introduced in 2005, and was first used as the GM factory-fill automatic transmission fluid for model year 2006. All Dexron-III licenses expired permanently at the end of 2006, and GM now supports only Dexron-VI fluids for use in their automatic transmissions, although fluids asserted by their manufacturers to meet Dexron-III standards continue to be sold under names such as Dex/Merc. These fluids are not regulated or endorsed by GM."
