It's California law that fluids with a significantly different viscosity can't be "recommended for use in..." which is why it doesn't say Mercon V on the bottle but it does on the site.
I would happily use Maxlife ATF in any import transmission listed on the bottle, and any domestic with LV fluid specced (Merc LV/Dex VI). Why not domestics that spec higher viscosity fluid? Because fluid is easy to come by and cheap (this isn't always the case for imports). For example why use Maxlife when Valvoline Mercon V with the correct viscosity is right next to it on the shelf at O'Reilly, or you can get Castrol licensed Mercon V at a different parts store in town (Carquest/Advance). Same thing with regular thicker Dex III for an older vehicle, why waste the money on Maxlife when Dex III is "correct" and cheaper. Yes, I know Dex VI is "backwards compatible" but after my experience with transmission issues after changing the Dex III to Dex VI in my Suburban... maybe it's a coincidence it had 214K miles, maybe not.
Anyway, I happily use Maxlife ATF in my Escape which has a 6F35. I am using it instead of the OEM specified fluid (Ford Motorcraft Mercon LV) because the OEM fluid was getting dark very quickly even after changing, which is apparently common with the Motorcraft fluid. I'm going to do a few more changes with the Valvoline and see if it's any different. Even if the color is still dark, the Maxlife did improve shifting immediately.
The odd time I find it locally in Walmart, but lately they are out of stock.
