However, on my car, the recommended ATF has been replaced by Power Steering Fluid, and who knows if it was done properly?
I read something in a Supra Owner's Group site that if the steering starts feeling wonky, and there aren't any problems with the rack, that the fluid needs to be replaced. The instructions are clear, and I have better instructions from someone who followed the TSRM and came up with a couple tricks (so you don't have hydraulic fluid spraying all over the place...) but how can I flush the system and refill with the correct ATF? Should I just start the flushing process with ATF and continue for an extended amount of time?
