Transmission Fluid Leaking problems of the 2009 Dodge Grand Caravan

My van was bought new by me and has around 51,111 miles on it. About a month ago transmission started leaking out of it. The transmission is completely sealed, no way to check it's level or change transmission fluid. The old 1/4 inch tube that usually would hold the dip stick is much shorter (about a foot) than a normal transmission dip stick. It took me awhile to find it. It is one of two transmission lines going from the transmission and going to the radiator and the leak is in the back of the engine where you can't get to it without dropping the transmission. . . Dodge has a 100,000 warranty on the transmission and engine but this line is outside the transmission so they claim it's not part of their warranty. . . Regardless the tubing they use has to be defective because most people have driven 100,000's miles without having this non-moving part to fail. I have their extended warranty but they claim it's not covered. So how does it get reported. I had to pay over $500 for the wiring harness in my automatic sliding doors that obviously the lower arm on the door kept rubbing and rubbing until it frayed the plastic covering causing my wiring harness to break but when I bought it in their was no recall yet so I had to pay for the repair myself and then around 6 months later I had to pay for the repair which I haven't got I.
