what wieght transmission fluid

Post by abe »

I am going to change the transmission fluid in my 54 F100. It has a 3 speed tranny from a 1970 truck?

What weight gear oil should I use? And how much will it take?

thanks!

I don't know about the 3 speed trannys, but they recommend 50 weight motor oil for the NP435's.
