The compatibility of VI to III is often debated. I'll leave that alone. I've a DexIII vehicle and I use an Allison spec'd product that is DEXIII spec'd. Castrol Allison TranSynd

Ive been using Mobile trans fluid in my 93 auto and red line for my power steering. Probably more important than the brand name is that you are changing your fluids all of them when needed.

A good quality ATF that meets the DexIII/Mercon spec will be fine for GM auto trans vehicles. Most ATF synthetic fluids will also meet the Dex VI spec too.
