mixed mercon into a mercon V transmission
I just dropped the pan and added 4 quarts of Walmart regular Mercon ATF instead of Mercon V by mistake. Have gently driven 30 miles with no problem.
Aerostar 1997 4.0 motor AWD tranny is 5R55E ?. 200,000 miles. Old oil was not red, kind of brown. It only took 4 quarts.
How serious is this? The body is bad and everything is worn out by owner who wants to sell me the car. I'm worried about finding a reliable place to flush it if necessary.
Do I have to flush it?
What sort of problem should I expect if I don't?
I have read these posts, but they don't discuss 45% incorrect oil. Total capacity is about 10 quarts.
