The "right" tranny fluid - after a rebuild
Presumably synthetic, right? But which one?
I was told today that if you start with a clean rebuild you can use virtually ANYTHING (including low viscosity motor oil!). The same resource said that Toyota has a proprietary synthetic for Lexus that's about $100 per fillup, but it's the "best." What do you think?
Seems to me that the soft parts in the tranny are designed for a specific set of fluid characteristics.
