One problem related to transmission fluid leaking has been reported for the 2013 Dodge Ram 1500. The most recently reported issues are listed below.
A few weeks earlier I heard a horrible grinding noise from my transmission while driving at 30-35 mph. I took it into the dealer and they could not duplicate the problem and inspected my vehicle stating that there were no leaks, fluid was fine and transmission was in good shape. I then got my vehicle back after 18 buisness days in the shop and I heard the grinding again (950 miles later). I got under my truck to look and found that my hydraulic cooler lines were leaking and my transmission looked like it had 200,000 miles on it. This is very strange because I have no documented work on my transmission and it went 19793 miles with no leaks and randomly started to leak??.
