I know you guys prefer amsoil tranny fluid. I agree amsoil is one of the best tranny fluid. However I am going to switch to Mobil 1 ATF (fully synthetic) for my 2000 4Runner(4WD, SR5, automatic) since I've used Mobil oils for years.

I went to Autozone today trying to buy 4 qts. I asked the clerk to make sure the Mobil 1 ATF is safe for my truck even I've known it is (any Dextron III type should do). However the Autozone's system showed unknown type of tranny and I was instructed to consult Toyota dealer! That was weird!

Can anybody who used the Mobil ATF tell me how this tranny works with 4Runner? Thanks in advance.
