What is a transmission wiring harness? What types of transmission harnesses are there?

Transmission wiring harness is the electrical wiring harness used in the transmission system of an automobile. It is responsible for transmitting power, signals and data to the various sensors, control units and actuators in the transmission for proper operation and control of the transmission.
Transmission wiring harnesses can be divided into the following categories according to different models and transmission types:
1. Manual transmission wiring harness: The wiring harness system for manual transmissions transmits signals to clutch sensors, transmission gear switches and other components. The manual transmission harness needs to be connected to the transmission's control unit and operating lever to ensure smooth gear switching.
2. Automatic Transmission Harness: A harness system for automatic transmissions that transmits power and signals to the transmission's control unit, sensors and actuators. The automatic transmission wiring harness needs to transmit various signals from the vehicle, such as RPM, oil pressure, vehicle speed, etc., to enable automatic gear shifting and transmission control.
3.CVT (Continuously Variable Transmission) harness: The harness system for CVT transmits power and signals to the control unit, sensors and actuators of the CVT. the CVT harness needs to transmit various parameters and signals to achieve control and regulation of the CVT.
4. Dual Clutch Transmission Harness: A harness system for dual clutch transmissions that transmits electrical power and signals to the transmission's control unit, sensors and actuators. The dual clutch transmission harness needs to transmit various signals from the vehicle while enabling the control and synergy of the two clutches.
5. Electric Vehicle Transmission Harness: A transmission harness system for electric and hybrid vehicles. This harness needs to transmit power and signals to the electric transmission or transmission control unit to enable coordinated operation of electric drive and energy management.
When designing and manufacturing transmission harnesses, the following factors need to be considered: electrical performance requirements, environmental resilience, protection ratings, tolerance to extreme conditions such as vibration and temperature, and compatibility with other vehicle systems. In addition, transmission harnesses need to meet reliability and durability requirements to meet the challenges of long-term use and complex operating environments.
Therefore, the manufacturing process for transmission harnesses includes requirements analysis, design, material selection, wire processing and insulation treatment, connector installation, testing and quality control. Through strict manufacturing and quality control processes, we can ensure that the transmission harness has high quality, stable and reliable performance to meet the requirements of automotive transmission systems.
