For phase 1, I have some left over Dexron-6 ATF fluid left at home.
For phase 2, I would use better quality such as Redline D6 ATF (as per recommendation in RL application guide). Lots of folks swear by authentic ZF or Ravenol ATF at $25/liter ...
Best feedback I can provide is to make sure that whatever fluid you are using meets ZF Lifeguard 8 standard. With that, it should matter that much what brand fluid you use.

If you are doing this DIY, I'd suggest simply following normal procedure. If you are concerned about the fact that a lot of the original, dirty ATF does not get drained from the system on a standard ATF change, then I would suggest getting a good Indy shop to flush the system before they replace your oil pan and filter assembly.

Many people will tell you that, if you flush the system, the transmission will fail right after that. That is not the case.
