2001 Mercury Sable 6 cyl Front Wheel Drive Automatic 101000 miles
My 2001 Mercury sable is not shifting down the way it should. If I drive like 30 mph and stop and try to go it will jump because it hasn't shifted all the way down. The fluid was low, I checked with the motor running and added some. Also, when I had the dip stick out and shut the car off, the fluid started bubbling up and out of where it goes in and it smelled hot. Could this be caused by a bad filter or does it sound like a problem I need to have a professional fix?
