I have a question, hoping someone has some answers, it doesnt happen all the time but from time to time while driving my OD OFF light will start blinking real fast. My explorer has been shifting a little funny lately too. When i come to a sudden stop and go to pull out its like its stuck in between a gear then jerks and takes off. what can i do to fix it or what are my issues. i was thinking about changing the tranny fluid and filter and putting lucas in.
