Dextron III is what I run as recommended by my transmission builder. When I asked about running synthetic he said to save the money and change the fluid more often. quote from the Valvoline web Q&A page Quote:
What is the difference between DexronIII/Mercon and type "F" transmission fluid?
The Valvoline Type F transmission fluid is a high quality NON-friction modified fluid. Dexron III/Mercon includes friction modifiers in the fluid additive package.

I have heard Dexron from some trans builders and Type F from other builders. Maybe we should use 50% dexron and 50% type F. I have been using Mobil 1 ATF. It is Synthetic and for all transmissions, at least that is what I was told. I have aprox. 950 passes on the 727 in the Lebaron with same Mobil 1 fluid as the first pass. This is the beginning of 3rd season. No band adjustment or any maint. at all. Still cherry red and smelling sweet. Won S/P and made it to semis in FB this past sat night. 15 passes in 1 night. Now let me go find some wood to knock on.
So tell me how are you going to save money by changing the cheap regular fluid more often? Synthetic is the only way to go in my opinion. Having said that I use Hyundai SPIII in mine, it's synthetic and I get it for free, can't beat that with a stick.

Really depends on the application. We've tried everything from synthetic to John Deere tractor fluid and when it's burned it gets changed and it's burned a few times per race.

I run dextron, type F, Mobil 1 synthetic and hydaulic oil in mine over the years and to be honest I didn't see any earth shattering advantages of one over the other besides the hydraulic oil lowering the stall a few hundred RPMs.
Never had failures with any of them. I think the most important factor is building the tranny right, then run whatever fluid you want....

I just put the regular B&M in mine,because it is the type F fluid. At the cost of it I hope it is a better fluid. B&M will tell you unless you are running one of the new metric transmission don't run theirs or anyone else's synthetic fluid.
ATI has just come out with a synthetic fluid that you can use in the older transmissions.(ATI also said not to run synthetic before they come up with their own brand)
All of the above was told to me by techs at ATI(whose trans&converter I run)& B&M.
