Maintainence

,

is it ok to use trasmission fluid in your power steering reservoir, if not what are the problems that will happen if you do?

In many applications ( Ford for one ) it is exactly the same stuff.
read owner’s manual.
read bottle.

thank you was just checking

Ken said “many applications,” not “all applications.”

You better read your owner’s manual carefully. I don’t think I’d mix automatic transmission fluid and power steering fluid.

Check the owner’s manual. That OK is for some cars, not all! I have no idea about the Kia Rio
