Transmission Woes
 This is my first Nissan. First off, I love the looks and design of the unit. After my first road trip with the unit 1500 miles I started experiencing the dreaded torque converter problem you will read about. It has lived at the dealer for weeks while they an Nissan diagnosed the problem. The long and short, there is no known cure for these symptoms. 30-45 MPH (5th gear) torque converter clunks with slightest variation in RPM (up and down). Worse yet is that at highway speeds (cruise on) down a hill, it happens over and over again (worse). Now 15000+ miles, can't stand to drive the truck because of the clunking. Make sure that you keep on the dealer for a fix! This condition is not right!
