What are gearbox controller faults related to?

Important data are received from the speed sensor; these are data updated in real time; in addition information is received from sensors in the wheels about the engine speed. Apart from this, sensors in the turbine and throttle ratio sensors are used. This allows the controller to determine the optimal gearshift characteristics depending on how loaded the engine is. In new cars, the driver has the option to set the economy mode or sports mode, which will affect the operation of the controller. The controller monitors the temperature of the transmission fluid, communicates with the cruise control and cooperates with the traction control system. If the controller is damaged, you may notice incorrect gear ratios with inappropriate engine revolutions; in some cases the gearbox may come to a standstill. In this case, you should visit a specialist who will know how to locate the fault. The fault in the gearbox control unit may be related to either the electronic or the mechanical components. The cost of repair can be quite high due to the complexity, especially since not every specialist will have the appropriate equipment or appropriate software which will make it possible to locate and correctly remove the fault.
