The cheapest generic 80W-90 or 85W-140 gear lube will be fine for that transmission if it's in good shape.

If it's getting "loose" - we used to fill them from 1 gallon jugs of Lucas Oil Treatment.

If I had the owners manual I wouldn't be asking you all.
 
I had the same question and hunt to find the proper fluid for my 84 F150. There was no easy way to find the answer. My trans expert told me "probably gear oil". We unscrewed and removed the shifter (for a different reason) and sure enough - the sulfur smell gave it away. So, can you sample what is in there? of course, you can't rely on the PO having maintained the correct fluid - it is 41 years old...

True, but my point is that an answer by random people on the Internet is somewhat less reliable than what the manufacturer publishes.

What I saw online was 85W-90 gear oil. Is that what you've been seeing?

duh. I love it when people respond with that.... exactly - if I HAD the owner's manual why would I subject myself to potentially ignorant and snarky responses . of course, at times I am guiulty of thinking that y'all are part of my family. of course, any police officer will tell you that holidays bring family members together that dont belong together....

I'm just trying to be funy here - not offend anyone... heh heh heh

realistically anyone that posts questions here is trying to learn and also rely on the collective knowledge and experience here at bitog

On the other hand, there are more posts by people who haven't even looked in the manual than there are people who don't have one to consult. Many times they think an answer here is more better than what the manufacturer states.

Considering that I think my question was a reasonable one. I didn't ask it in a snarky or offensive manner.

fair enough. and I was just trying to be funny - not trying to pass judgement on your question or comment. I actually think the same thing - especially on newer cars: "why is this person asking instead of checking the manual." I have an extremely dry sense of humor - and far too many of my friends are the same way.

as I spend way too much time trying to figure out mysteries with older cars; it can be a challenge. I always try to hunt down an owners manual or service manual. I have quite a collection of them. what fluid DOES go in a 1976 F100? and you can never assume that the PO has the proper fluid in there. another favorite is when a mfr specifies their own part number for a fluid spec or part. of course some sicko like myself is gonna try to source a substitute.

I love it that some manufacturers have manuals easily available. for instance, Yamaha manuals are easy to find. Nissan Service manuals are available free if you know where to look. Ford Trucks? meh.

This is true. I have to use GL-4 oil in my 78 Jeep CJ7 because use of GL5 will hurt some internal parts.

That's what I use in my CJ7 and also all I could find that was a GL4.
 
Here in Spain you can get a Ford 75W-90 GL4 oil from dealerships that is meant for old 70s gearboxes with yellow metals, i put that in my Capri's gearbox and it seems to be pretty smooth.
