what transmission fluid for a ford 335 utility tractor?

[pabble]

I can't seem to find the specs for the correct transmission fluid to use in my ford 335 tractor - can anyone tell me the best choice?

My 3910 calls for Ford 134 fluid. I'm guessing yours would be the same. Do a Google search for results. Also do a Google search to get an equivalent fluid in a different brand if needed.
