Default Tranny fluid?

I am going to drain/refill my tranny fluid soon and i was wondering what to put back in it. Should i just use the stock ATF, go to a synthentic ATF, or get GM sycromesh?....Any input on these and opinions are appreciated!

Use 4 quarts of Mobil 1. That is what we have always ran in our units and even with a stock transmission seams to work well.

Use Dexron 6 -- fully backward compatible and much better all around... longer life than Dexron 3!

Pennzoil Synchromesh ATF. Just got some from Autozone for $6/qt. It's the exact same formula that GM sells for $10+. Works great!

I just did clutch and used mr transmission dextron 3. Not sure what it really is but it was cheap. And now just changed it out for penzoil synchromesh. It seems to be shifting better. Was a bit notchy with the no name dextron. Mobile 1 is also likely good after all sure six speed guys know a few things about t56. Likley be going with one of them next season possibly.
