Overhaul of automatic transmission (Peugeot 406)

The gearbox is a very complex unit, and its repair must be carried out in a specialized workshop. Before repairing the gearbox, it is necessary to determine the nature of the fault, which can be electrical, mechanical or hydraulic.

Do not remove the transmission from the vehicle for repairs until the fault has been professionally identified, as most tests require the transmission to be in the vehicle.
