Wanted: a gearbox controller – original used controller
For the proper operation of the gearbox, a controller is needed, which, on the basis of data from a number of sensors placed in the vehicle, can adjust e.g. the pressure and temperature of the fluid in the gearbox. The controller also monitors the position of the lever, and is responsible for the correct gear depending of the speed of the car and engine speed. While you are driving, the controller constantly communicates with many different systems and selects the appropriate parameters for your gearbox in real time. It is a module that can fail over time, in which case you may have a problem with changing gears, or the gears may change their position in an uncontrolled way. Of course, it is then necessary to make the necessary repairs, or to replace the entire control module.
Looking for a gearbox control unit
Many drivers consider repairing the gearbox control unit, but it is important to remember that it is a fairly complex system that varies from vehicle to vehicle. It has some electronic parts and a circuit board that can fail. It can be a failure involving solder connections, chipsets or the software. So finding a fault can be quite a problem; it will often require the right electronic knowledge as well as having the right software. An additional problem can also be the availability of parts; some controllers may no longer be manufactured.
Therefore, the best idea would be to replace the entire controller; it is worth looking for a remanufactured controller which will be a 100% operational component. Of course, there are reconditioned controllers for different models of vehicles. Buying this type of component you can be sure that the controller will fit into your vehicle and will properly read the data from the sensors, and properly manage the work of your gearbox.
Drivers faced with the problem of looking for a gearbox control unit can go to Ecu Automatic Gearbox and find the right gearbox controller. Buying a reconditioned controller may be a cheaper option than trying to repair it.
