Probably

But you have to remember, Walmart uses different suppliers and can switch at any time when economics allow. On top of that, even in different areas of the country could have different suppliers at the same time.

But 7.5 sounds in the ball park

Also remember it's mineral based and may shear about 2 cSt in service. Consider a synthetic like Maxlife or dex 6 for greater life.

It depends on who the supplier is, and among suppliers there is variance between runs. Here's a data sheet from one of their suppliers:

Coastal DexMerc (Warren Oil)

The last MSDS I saw for Super-tech ATF dated 2012 was from Citgo. Citgo Transguard vis is rated 6.95 @100C. It should be the same for ST, but I haven't seen any reports.
