How many times have you changed the fluid in the trans ? I bought my 2011 with 51k and immediately dropped the pan and installed a drain plug. I then dropped and swapped 4 quarts at a time, every 100 miles, until I had run 12 quarts out. Fluid looks like new. I now drop 4 quarts every 3rd oil change (about 20k) and have never had an issue, and I've pulled my car and camper trailers over 20k of the 84k I've driven it. Mine is a 6 speed, is the 2015 the 8 speed ?
