thats an excellent point jeremy! chain drives use ATF and gear drives take gear oil (respectively)

I'd go with either Mobil 1 or Motorcraft synthetic 75w90.

even the walmart gear oil will work well in there for only 2.00 a quart. it surpasses the original standard for that truck.

Thanks, that's what I used to run in my '75 F250 with an NP203. Someone told me I should use 30W. That seems kind of thin for a gear box. How about 10W40 for the winter? Is that still too thin?
