My transmission went out at almost 61,000 miles -- Chrysler replaced it, but it took about two weeks. Chrysler dealership had to run transmission viscosity test to determine it was "not my fault." Of course, it wasn't, so they replaced it at no charge. However, my EcoDiesel is also my tow vehicle -- I was disappointed that Chrysler would not provide for me a replacement while my truck was being repaired.
