Fluids?!?!
 

i read a lot of threads in the modular 4.6L and i havent seen anybody sayin wich fluids to use if there is im sorry i missed it....im gettin ready to change my tranny oil in my 03' GT (Lorretta) and i was lookin to see if there was any other tranny fluid that was better than what the dealer offered me and anyother fluid changes that i might have missed or not know about....thanks for any help

royal purple
valvoline
mobil 1
castrol

i browsed all the name brands but now im not sure what tranny fluid type to use for my tranny...i have the TR-3650...i didn't think it was so complicated to choose a tranny fluid!

A lot of people are using this mix and seems to be working

Did you use that mix or did you just use some straight oil?
