Traction problem

hello friends good evening 407 vehicle sometimes had a traction problem, even though it was not connected, I was connecting to the device in the past. There is a couple of friends who are in the form that I have researched falling down to 3rd gear, but if there is a friend who knows they have not written the solution of the problem, I would be very happy if it helps.

The turbo must be neglected. Check the turbo hoses or something, whether they come off or forget to install a master.
