There are better options than type f. I am NOT saying it won't work, but there are better fluids.
Guys always recommended type F in a race trans, because it was a straight fluid with no friction modifiers, which resulted in firmer shifts, but a not quite as long lasting fluid. That still holds true, but this isn't the 60s or 70s. In a race car, use a race fluid. If you want the absolute cheapest, use the Type F

There are better options than type f. I am NOT saying it won't work, but there are better fluids Better for frictions and hard parts life, shift quality, ET/MPH, temperature, and/or consistency? Is there one that you see ahead of the others in every consideration or are there trade offs? Some folks will give up durability for ET and vice versa. I've tried others, both dino and synthetic, and both 2 and 3 speeds, and it always resulted in evidence of increased clutch/band slippage, more trash in the pan and/or wear. Always come back to the Type FA Valvoline or Napa or Carquest brand. Seemed to work the best with my limited testing and it's cheap enough you can service the trans every 20 or 30 runs without having to eat ramen noodles for lunch everyday. I've never had an opportunity to try different oils in anything with data logging to see what the difference may be there.
If the results don't match the theory, change the theory.

I've never had an opportunity to try different oils in anything with data logging to see what the difference may be there. I can tell you this. The fastest doorslammers on the planet, that run OEM type transmissions, don't run type F. In our own car, with a 2 speed Turbo 400 and making 2500HP, we run John Deere hydraulic fluid. We data log everything, even on the trans. This gives us the best performance and reliability. Also, most "race" trans fluids that are not synthetic, are just hydrostatic fluid with some color added. It's VERY heat resistant, doesn't foam, locks up tight and has very good wear characteristics. The clutches in our 400 have been in there 3 seasons...........The tractor fluid while not as cheap as Type F, is not bad if you buy it in 5 gal buckets. What was absolutely the "cheapest" and "good enough" was never the criteria I use to buy race car stuff though

Type F here.. I can get it to last years.. till I'm ready for a tear down  You can't "get it" to last years.....it just does based on the amount the trans gets used and the slippage. Given identical temps and slippage, type F has the lowest service life of about any trans fluid.

I talked to Jim Paquet a few years ago who owned JPT( Jims performance transmissions) now retired
His brother Ray races a SS/ B thunderbolt. Very well known family.
Jim built trannies for pretty much everybody in the Ford stock and super stock world. In addition to all the others.
He told me the best fluid for a race trans 727 was type F. I would consider him as much an expert as anybody in the country.
I expect most any racer would change tranny fluid at least once a season anyhow.

Given identical temps and slippage, type F has the lowest service life of about any trans fluid. Say what ever you want Don.. when I was racing (most every weekend) it lasted 4 years. I pulled the pan to check things and put it back together with a new filter and fluid

I don't doubt anything anyone says based on years of experience, but when it comes to what is "best" for anything is a very random question and has no clear cut answer. If you have been building race trans for 30 years, always used Type F and never had many problems, sure, you can claim that the best. Same with cams, intakes or anything else............but this is 2016. Hard to fathom that a very basic oil from the 60s and earlier, is the absolute BEST fluid you can put in a race trans. Why aren't we all still running straight 30W Quaker State for oil. Or "mushroom" cams, pinion snubbers, casler tires or anything else that was the BEST in the 60s.
Like I said, Type F will work and obviously many still use it. I only said there was better fluid and I believe that

I dont claim anything.. it works for me and its cheap... I dnt know why I worry about cheap because I dont change it very often.. I have tried the TSC tractor fluid once to see if I could increase the stall.. that was the same as the Deere fluid

Interesting I won't even use John Deere Hydraulic fluid in my John Deere ...stuff burnt up like crazy. I do have an extra 30 or so gallons I should try in an automatic.
Edit: thinking to myself out loud which John Deere Fluid?
Hyguard, low viscosity hyguard, hydrau, hydrau XR (the last 2 are speced for construction equipment) I assume you don't use the bio stuff.

When I asked A & A Transmissions which fluid they recommended, they said +4. Most of the +4 is now synthetic and double the cost of ATF or F. I would be interested in hearing more about the hydro oil.

Is this an in service trans that you're just doing a fluid and filter change on, or is this a fresh built unit?
did you build the trans, or did someone else do it?
if it's a trans your just doing a service on, i would just use the same type fluid that came out( if you know).
if this is a fresh trans that someone built, ask them, they built it, they know what they like in their builds.

I use John Deere fluid. Was highly recommended on the turbo forums and yellow bullet. Tightens the stall a bit, but I've had no problems on the street. 440 w/ S475 Turbo & 727.
