The truck: 1979 F150 Custom 4X4 that came OE with an inline 6, but now has a 302 V8. I have an NP435 4spd trans mated to an NP205 transfer case. If I change the fluid in both, I would like to know what fluid to use and how much fluid to use in each. I have read the archived threads on this subject already, but they are old and would like to hear any/all modern educated feedback on this subject. Thanks!
