Transmission fluid keeps your transmission cool and lubricated; over time it degrades and loses effectiveness. Most manufacturers recommend checking fluid annually and flushing it every 30,000-60,000 miles, though some newer vehicles have longer intervals. Neglecting transmission service can lead to costly repairs. Castle CDJR of Naperville's Service Team uses the correct fluid for your Jeep, RAM, Dodge, or Chrysler and follows manufacturer guidelines precisely. Regular transmission maintenance improves shifting smoothness and extends transmission life. Check your owner's manual for your specific schedule, then call (630) 864-6683 to book service.
