i mean since i live in dry environment with an average of 72F in winter and 109.4 F in summer, my average transmission temperature is 194 f ,
i would like to try newly released atf from high quality aftermarket company like : redline d4 , amsoil multi vehicle ATF ,petro canada duradrive mv , Wolf Vitaltech Multivehicle ATF , Liqui Moly ATF Top Tec 1200 .... etc , these are more than 6.9 @100c viscosity and aren't vintage
instead of low viscosity
mazda fz that has 5.8 @100 .
and i know one person who has aisin fw6ael and used mercon atf
View attachment 105933 instead of
mazda fz for19k miles and didnt noticed any diffrence
another person who has aisin fw6ael and instead of
mazda fz he used
pure guard global atf with 7 @100c of viscosity for 1000 miles with smooth shifting .
how to determine if the fluid isnt suitable other than used oil analysis ?
