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?
