Hey guys, I'm looking to see what transmission fluid i can safely use in my 2000 aw4, i know not to use atf +4 but i'm confused about the difference between dexron III vs dexron IV vs dexron VI? The FSM called for dexron III correct? I thought dexron III was replaced by dexron IV but then i read that dexron IV is thinner viscosity than dexron III. But now it looks like dexron IV has also been replaced. I guess what i'm asking is when i go down to the auto parts store which bottle do I pick lol, I was looking at the castrol transmax vi (gm licensed dexron-VI). Or would i be better off with a house brand dexron III compatible (like napa)?
