while driving to Atlanta from Houston, pulling an empty car trailer, My 2009 1500 4x2 truck popped a code P0740. after driving approx. 200 miles. Checked fluid a little low, added atf and cleared the code. went aproxemantly an other 200 miles and the trucked popped the same code. this happen all the way to Atlanta Ga. every 200 miles. But only when I was pulling the trailer. Never had the problem once the trailer was disconnected.
