Agree, I do prefer Valvoline though.

It's actually Dexron (no "t"), and most places sell this "Dex/Merc" stuff now. Note what it says in the small print near the bottom.

I bought this and put it in my '78 Toronado. Works fine.

That was the old racing trick in the 1960s. Use Type F in a GM trans and you get firmer shifts. The B&M Trick Shift fluid was pretty much just Type F.
