Are you saying you put power steering fluid in the power steering reservoir by mistake as it should be Dextron/Merc transmission fluid? If you didn't start the car yet, get a turkey baster and suck out as much as you can and replace with the correct trans fluid. Start the car and turn the wheel lock to lock to remove the air out of the system and check the level again.


I'm pretty sure Juan was saying "put power steering fluid in the transmission" I'd say that an ounce or two may not do much (if any) harm ,manufacturers recommend specific fluids for specific systems but the voodoo behind what is in a product is limited to the label telling you nothing ( every fluid in the world could be chicken fat for all the manufacturer's label say) Ford use to say use type F transmission fluid in the tranny AND in power steering - voodoo at best!
