My 2001 Kia Optima starts out fine then it will skip second gear and shift very hard into third and stay there. The dealership checked the car and said to drain and fill the trans, did it, didn't work. The trouble codes are "P0715" and "P0720"can I just replace the Input/turbine speed sensor and the Output speed sensor :?
