Walmart Supertech is made by the same company that makes Mag 1. Very possibly exactly the same fluid.

If it says type F on it I run it and I race more than most. Mags, Walmart, whatever. I build my transmissions so I see what is going on. Ohhh and there isn’t a much harder test than a 6000 Stall converter on the floorboard with a transbrake.

Im with pittsburgh racer. Any type f, I have ran a bunch of different brands. Cheapest I found is at rural king providence automotive brand. You can order online and its $5.50 a quart. Last year I bought a few cases of it for $4 a quart. I am also trans brake and 6500 stall converter.

Very possible.

However, Mag 1 oil is indeed the cheap stuff sold to shops that do cheap oil changes and I know a number of guys using Walmart Type F in good transmissions. Not Top Sportsman level stuff. More like Stockers and Super Stockers.

Personally, I would not be likely to use it. Mostly because I try to avoid Walmart.
