Therefore, you should take your 2008 Jeep Patriot to a qualified mechanic or Jeep dealership for an automatic transmission fluid check and service. Trying to check it yourself will not yield accurate results and could lead to further complications. Instead of trying to check it, focus on noticing symptoms of low or failing transmission fluid like slipping, rough shifting, or whining noises from the transmission. These are good reasons to have a professional check the fluid and the transmission's overall health.
