I'm pretty sure that the OP has little interest in how wonderful anybody's Jeep product is. I would also question the OP's understanding of the prep. procedure for towing, as it bears little resemblance to what Honda specifies for two CRVs we have towed, or the same info. I located on flat towing the 2010 Fit automatic, while doing a quick search. I would recommend re-reading the manual and following the process carefully. Foot on brake, cycle shifter from P to low, then up to D. Hold brake and keep in D for FIVE SECONDS. Shift to N, let vehicle run for three minutes. If the vehicle is accidentally shifted from R to N it WILL cause damage to the trans. I just traded our 2013 in with 67K on the ODO and another 45K+ miles of being towed. The trans was serviced at 30K intervals, and it had zero issues. The OP is either unlucky, or damaged the trans. by accidentally doing the process wrong.
