I don't doubt it that leaks may have developed after adding Dexron ATF in those two cases, but was it coincidence, were the seals ready to go anyway or was it caused by the Dexron? Not sure that anyone really knows. I bet there are lots of guys still using Dexron ATF with no leaks. Is it wise to use power steering fluid? Maybe.

Been using ATF in mine since day 1 with no issues though.
