Which tranny fluid?

I am putting a ZF6 tranny and a NP271 transfer case out of an 01 super duty in my truck and I am not sure what type of tranny fluid they take? Can someone let me know what spec. Ford recommends?

Thanks

Re: Which tranny fluid?

Does it not have a spec. like Mercon III, IV, or V?

Why would you do that if they recomend 3?

Re: Which tranny fluid?

There never was a MERCON 3 or III fluid. Didn't exist. There was DEXRON III/MERCON, which is now an obsolete fluid.

Ford stopped licensing MERCON a couple years ago. They changed MERCON V to be compatible with all transmissions that used MERCON. So now MERCON V is the right fluid for your trans.
