never looked into this but why doesn't it make sense to put ps fluid or ps for our cars? anyhow i used the STP power steering flud & stop leak. why the hell would you use auto transmission fluid in ps ? i'm just asking this cuz i just don't know and just going w/ common sense.
just found this:
"Under NO conditions is ATF to be used in power steering systemsATF will become very hot under loads and start to break down causing electrochemical degradation, this also happens with power steering fluid but not as fast was with ATF. "
