CHEVROLET ORLANDO Gearbox/Automatics 6.speed from 165 km/h

Since February 2012, I have been driving the Chevrolet Orlando Bj. 10/2011, 1.8 liters, automatic. Already after a short time I noticed that from 165 km/h the gearbox automatically switches back to the 5 gears. From 165 km/h to the final speed at approx. 190 km/h the vehicle remains in the 5th gears. Neither automatically nor manually can this flaw be eliminated. The gearbox should be learningable, but it is not. Only at 165 km/h the gearbox switches back to the 6 gears. Any acceleration at this speed is connected with a reversing into the 5th gears. Up, down, up. On the mountain and when overtaking this is unbearable. I have not been able to try out faster than 190 km/h depending on the driving method. Of course I was also in the technical workshop at Chevrolet. 1 x in Bad Godesberg to be silent. The vehicle we indicated with approx. 7,3 liters in the average. In fact, the consumption has to be around 10 to 12 liters depending on the driving method. Of course, I was already in the technical workshop at Chevrolet. 1 x in Bad Godesberg. And not to be recited twice the transmission. I have been told about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing. And the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same thing about the same
