Automatic Transmission Torque Converter Problems of Hyundai Veracruz

Hyundai 2007 Veracruz limited. Does not downshift properly. On multiple occasions I have had to slow my speed in freeway congestion and the car does not downshift, even with tapping on the brake. The car stays in 5th or 6th gear to speeds as low as 20 mph. I have literally had to stop the car completely to get it to shift down. The car has no power to move quickly when necessary in these conditions (such as for a lane change). Additionally, the car does not shift properly at approximately 30-40 mph and the engine lugs, causing a very bumpy ride and near stalls on hills . This condition occurs with driving on inclines, in stop-and-go traffic such as freeway slow-downs, and with around-town driving at a standard municipal speed of 30-35 mph. I have had my car to two different Hyundai dealerships for diagnosis and service on five separate occasions. Despite that two mechanics, two service managers, one general manager, and the factory representative have all ridden in the car and verified the condition, the fact that the computer cannot diagnose a specific problem has resulted in zero repairs and zero resolution to this problem. Mechanics have speculated that the torque converter is not functioning properly, that the vehicle needs a new computer, and possibly that it needs an entirely new transmission but the factory representative will not authorize such repairs. He is relying entirely on a computer diagnosis instead of human logic and common sense. I am currently pursuing the lemon law in my state and Hyundai's current position is that "there is nothing wrong" with the car and they will do nothing further.
