It will likely develop a leak.
You need to use something to pull the extra fluid out. A turkey baster will work.
It depends on how much of it you have.
There is not much difference between power steering and transmission fluid. Many people use power steering in place of transmission fluid because it is cheaper.
I paid $ 129.99 at the GM dealership for power steering flush & fill with synthetic fluid.
Take a chicken baster and siphon some it out. That's why they put that dipstick on the cap.
All brands of steering fluid are pretty much made the same. Check your automobile's manual to see if there is a certain type of steering fluid that can only be used. If not, then the brand does not matter.
there should be a line where you pour the power steering fluid telling you when to stop. if there isn't it should say in your car manual.
Use a turkey baster to remove excess fluid
Probably about $3.00/pt.
