What type of fluid goes in a hubber 1330 trans and how often should it be changed. thanks

This is what I have allways run,,I allways check the color of the oil.Depends on the HP how often and how hard you run.

I have hubers in my cat. The Tag says type F , so ford type. I change mine every 20 hours when I change the oil in the speedmaster sixes. Hope this helps. Doug

Thanks for the help!

They told me to run type F also.
