Do this ...Pull your dipstick from the trans....Whipe on a clean white paper towl,nice and red.....pull your dipstick from a factory filled powersteering unit whipe on towl...its yellowish/brown and slightly differant consistancy,Will also have a differant smell than the DEX.

The thing is TOYOTA FACTORY filled the powersteering units with a generic powersteering fluid from the factory,SO YOU COULD PUT ALMOST ANY KIND OF FLUID IN IT TO TOP IT OFF,they choose DEX to top off cause its readily avaliable all over the world,and cheap,Same goes for there trans,untill recently when they wanted more life out of there fluids and higher PSI for efficiency and quality.There is nothing special about the fluid in the steering units and IT IS NOT DEXI,DEXII,or even DEXIII.

So IF TOYOTA States that if DEX III is acceptable fluid to run in powersteering,Then T-IV will work the same if not better where TOYOTA calls for DEXIII or equivalent.

I have alteast 6 or7 TOYOTA TSB specifically stating this...T-IV is backwards compatable for use in TOYOTA DEXI,DEXII,DEXIII trans and hydralic systems. Will DEXIII work fine...YES...Will T-IV work fine...YES,Will T-IV last longer and provide higher psi,and break down qualities..YES it will.
