MaxlifeMultivehicle has always been a thin ATF since it covered LV applications. They did also sell a Maxlife/Stopleak/DexMerc along side their Maxlife synthetic years ago. Many confused the LV with the Stopleak ATFs, since both were in the red bottle.
Valvoline 6.9cst and Castrol 7.4cst import ATFs are available if you want a 'standard' viscosity fluid. Pennzoil has a highmileage Platinum ATF at 7.2cst.
Any Mercon-V is an easy choice for Nissans calling for dmatic/dexroniii. No need to smoke the budget on the ol' transmission, that might just function better with a higher cst starting point.
