Status of vehicles: section 2017Matada3Anksela, driving over 71,000 kilometres for more than three years without incident。
Description of failure: the gearbox is frustrated when the vehicle rises。
CarThe gearbox is downThese may have been the result of: (a) insufficient fuel in the gearbox; (b) wear and tear on the plate; and (c) failure of the mechanical electronic unit of the gearbox。
Causes of malfunction1: weak tank oil。
The maintenance technician started the car, lifting it with a lift and opening the oil screw in the gearbox. At this point, if there is no oil spill from the transformer tank, it is judged to be insufficient. In the event of insufficient fuel in the gearbox, the internal parts of the gearbox are not working well and the temperature of the gearbox is raised, resulting in a setback。
Option 1: add transformer tank oil to normal liquid levels, 4s store costs around $150-200/l and maintenance shop costs about $100-150/l. Adding transformer tank oil is not covered by quality assurance and requires the owner's own expense。
Reason for failure: collider blades are worn。
The maintenance technician can use a vehicle-specific computer to read the data flow from the gearbox and analyse the gearbox's rise time. If the lifting is too slow, it will be possible to confirm that the plate is worn; if the piece is worn, it will also result in a setback in the gearbox during the lift or drop。
Solution 2: replacement of the clutch tablets, overhaul of the gearbox, and free maintenance of the 4s store during the quality warranty period. If released, the cost of the separate replacement of the centrifuges at the 4s store would be around $500-800 and the cost of replacement at the maintenance shop would be around $300-500; however, replacement of the pieces would require extensive modification of the gearbox, would take longer hours and would require replacement of more vulnerable items, with the total cost at the 4s store at around $10,000-12,000 and the cost at the maintenance shop at around $8000-10000。
Reason for failure: mechanical electronic unit failure of gearbox。
The maintenance technicians use their vehicle-specific computers to read the gearbox data stream and to observe whether the gearbox pressure is normal. If pressure is abnormal, the mechanical electronic unit failure of the gearbox is confirmed. If the mechanical electronic unit of the gearbox fails, it can cause excessive or too small pressure on the gearbox and, in turn, create a frustration in the rise or fall。
Solution 3: replacement of mechanical electronic units for gearboxes and free replacement of 4s during quality assurance period. If released, the replacement cost of the 4s store would be around $6,000-$8,000 and the replacement cost of the maintenance shop would be around $4,000-$6,000。
Summary: the vehicle in the case was tested as a frustration caused by the lack of fuel in the transformer tank, for reference to solution 1. In this regard, we recommend that other owners regularly maintain the car and develop good driving habits to extend the life of the gearbox。
