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

A transmission wiring harness is an electrical wiring harness used in an automobile's transmission system. It is responsible for transmitting power, signals and data to 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 car models and transmission types: 1. Manual transmission wiring harness: Used for manual transmission wiring harness system to transmit signals to clutch sensors, transmission gear switches and other components. Manual transmission harnesses need to be connected to the transmission's control unit and operating lever to ensure smooth gear shifting.2. Automatic transmission harnesses: Wiring harness systems used for automatic transmissions that transmit power and signals to the transmission's control unit, sensors, and actuators. The automatic transmission harness needs to transmit various signals from the vehicle, such as RPM, oil pressure, vehicle speed, etc., to realize automatic gear shifting and transmission control.3. CVT (Continuously Variable Transmission) Harness: the harness system used 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 realize the control and adjustment of CVT.4. Dual Clutch Transmission Wiring Harness: The wiring harness system for dual clutch transmissions transmits power and signals to the control unit, sensors and actuators of the transmission. Dual clutch transmission harnesses need to transmit various signals from the vehicle while realizing the control and cooperative work of the two clutches.5. EV Transmission Harnesses: Transmission harness systems for electric and hybrid vehicles. This harness needs to transmit power and signals to the electric transmission or transmission control unit to realize the coordinated work 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 class, 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 of 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 wiring harnesses have high quality, stable and reliable performance to meet the requirements of automotive transmission systems.
