The 46RE transmission is a four-speed automatic transmission produced by Chrysler. It is commonly used in Dodge Ram trucks and other Chrysler vehicles. The wiring diagram for this transmission is essential for anyone who wants to repair or modify their vehicle’s electrical system. In this article, we will discuss the 46RE transmission wiring diagram in detail.
What is a transmission wiring diagram?
A transmission wiring diagram is a schematic representation of the electrical connections in a vehicle’s transmission system. It shows the location and function of each wire, connector, and component in the system. This diagram is essential for troubleshooting any electrical issues that may arise in the transmission system.
It is important to note that the wiring diagram for the 46RE transmission may vary depending on the vehicle’s make and model. Therefore, it is essential to refer to the specific wiring diagram for your vehicle when working on the transmission system.
Components of the 46RE transmission wiring diagram
The 46RE transmission wiring diagram consists of several components, including:
- Transmission control module (TCM): This is the brain of the transmission system. It receives input signals from various sensors and sends output signals to control solenoids to regulate the transmission’s operation.
- Sensors: The sensors in the transmission system include the throttle position sensor, vehicle speed sensor, transmission temperature sensor, and others. These sensors provide input signals to the TCM to determine the appropriate shift points and other functions.
- Solenoids: The solenoids in the transmission system are responsible for controlling the flow of transmission fluid to regulate shift points and other functions. There are several solenoids in the 46RE transmission system, including the shift solenoids, pressure control solenoid, and others.
- Wires and connectors: The wires and connectors in the transmission system connect the various components and deliver electrical signals throughout the system.
Understanding the 46RE transmission wiring diagram
The 46RE transmission wiring diagram can be overwhelming at first glance. However, with a little understanding of the components and symbols used in the diagram, it becomes much easier to read and interpret.
The wiring diagram will typically consist of several pages, each representing a different section of the vehicle’s electrical system. It may include a legend or key to help identify the symbols used in the diagram.
The most common symbols used in the wiring diagram include:
- Circles: Circles represent connectors in the system. The number in the circle corresponds to the pin number of the connector.
- Squares: Squares represent components in the system, such as sensors or solenoids. The symbol may include additional information, such as the component’s function or part number.
- Arrows: Arrows indicate the direction of current flow in the system.
- Lines: Lines represent wires in the system. The line may include a number or color code to help identify the wire’s function.
FAQs
Can I repair the transmission wiring myself?
It is possible to repair the transmission wiring yourself if you have the necessary knowledge and tools. However, it is important to follow the wiring diagram carefully and take all necessary safety precautions. If you are unsure of your abilities or do not have the proper tools, it is best to seek assistance from a professional mechanic.
What are some common issues with the 46RE transmission wiring?
Common issues with the 46RE transmission wiring include damaged or corroded wires, faulty sensors, and malfunctioning solenoids. These issues can cause a range of symptoms, including slipping gears, harsh shifts, and transmission failure.
How can I troubleshoot transmission wiring issues?
To troubleshoot transmission wiring issues, you should first refer to the wiring diagram and identify the affected components. Check for any damage or corrosion in the wires or connectors and replace as necessary. Test the sensors and solenoids using a multimeter to ensure they are functioning properly. If you are still experiencing issues, it may be necessary to consult a professional mechanic.
Conclusion
The 46RE transmission wiring diagram is an essential tool for anyone working on their vehicle’s electrical system. By understanding the components and symbols used in the diagram, you can troubleshoot and repair any issues that may arise. It is important to follow the wiring diagram carefully and take all necessary safety precautions when working on the transmission system.
