What is the working principle of transmission gear selector?

09-17,2025

By changing the mechanical position of the magnet, the Hall sensor is able to receive different digital signals, and send digital gear signals (P, R, N, and D) to the transmission control unit (TCU). The TCU identifies the signals and controls the transmission to complete corresponding operations.

‌High-incidence period of failures of a transmission gear selector:

After the vehicle runs for 5 years or 100,000 kilometers, the failure high-incidence period of the transmission gear selector starts, and particular attention needs to be paid to possible failure symptoms.

Symptoms of a failed transmission gear selector:

Abnormal display of gear information.

Difficult or failed gear engagement.

Difficult startup.

Shock or unsmooth operation during gear shifting.

Causes of failures of a transmission gear selector:

Burned or oxidized gear selector contact.

Physical damage or wear.

Aging of electronic components.

Contamination (including metal impurities) or deterioration of transmission oil.

Chips imported from the United States are used. They feature high temperature resistance and more stable performance.

The material has been upgraded to PPS GF40 reinforced material, which is characterized by higher flame retardancy and corrosion resistance.

Welding points are elevated to realize firmer welding and facilitate easier welding operations during maintenance.
