I have a 2004 4Runner with a non-sealed, 4 speed auto. I believe it's an A340H transmission. the manual calls for T-IV fluid. I live in a climate where -40 is not uncommon in the winter.
Depending on who you believe, Toyota T-IV is either very good, or just another mineral based ATF with some specific friction modifiers, and likely made by Mobil (Mobil Super ATF 3309) and rebadged for Toyota.
I would like to put in a good quality synthetic for my cold winters. Here are a few options:
Valvoline Synthetic Import Multi

PetroCanada DuraDrive Synthetic

Mobil Super ATF 3309 (Probably OEM supplier)

Any thoughts on these products? I'm leaning towards the PetroCan product, it has a pour point of -54c, full synthetic and meets a lot of specs.
