You have three fluid reservoir's in your Patriot all use Dexron III or higher fluid. In the rearmost bay on the passenger side is a steel one with a cap. You have a plastic one on the rear right engine compartment and the Jack and slide one (if equipped) behind the rear drivers compartment. I think the one in the engine compartment is for the power steering and the one in the bay for the cooling fan.
You have to crawl under the coach to service the jack/slide one.
This excludes the brake fluid one in the front.
