Your new cap must be off of a whole different vehicle. SC300 requires DEXTRON III or higher ATF.

This is correct but I prefer ATF as it has better anti oxidation properties.

ATF for the win! haha i say that because first off its what lexus built it to run on, second its got more anti oxidant, third its not as thick as ps fluid allowing a smoother flow and less build up

something in ps fluid can (and apparently does) eat seals on jap power steering systems.
I frequently hear old school guys say they're the same. maybe 50 years ago when leaded gas was available they were, but not anymore.
