So I have a Ford 5r110 and spec'd for Mercon LV. It's a high HP application too. The trans is thermostatically controlled thus I cannot get a lower operating temp. Some fluids tout lower temps but the thermostat will regulate that. Anyway, I don't know if I should just run an approved or OEM Mercon LV or should I go to a boutique brand such as Amsoil? Problem I have with Amsoil is its a huge multi vehicle fluid. Ford made Mercon LV for my trans so I know it's appropriate and will work. But maybe something is better...
I know there are some smart guys here so I though I'd ask.
