407 Automatic Gear Problem

I bought my car 2 months ago, 2006 model 2.0 lpg. I have a problem for about a month, the vehicle is accumulating on ramps. rocketing does not work. it seems as if the steep ramps will stop. I took it to a few masters, they couldn't find any malfunction. The problem continues with the use of LPG or gasoline. Do I have any other friends who have this problem.

In how many thousand km there is a part called electro valve, most of the complaints in the forum are such / if the gearbox is malfunctioning, the snow and sports light should be blinking. I do not know much about the vehicle.

First of all, thank you for your interest.

some friends in the forum happened but if the valve fails it gives symptoms like I said it was said to be around 400 500 pounds, it is best to go to the service and connect the car to the computer and find the problem and introduce yourself in the dating section, more cvp will come.

It has to be connected to the computer and checked. Kick down may be a problem.
