Yes. Flush it. Then flush it again. Then again. Then hope nothing goes wrong.

No same thing work at ford motor company at one time we use dextron 2 for power steering fluid don't know what is being used now

Actually per the owners manual, for power steering fluid, Mercon ATF is specified as the correct fluid. Check out page 277 of the owner's manual
