The Allison 3060 transmission has been widely used in various types of vehicles, from school buses to military tanks. It offers reliability and efficiency, making it one of the most sought-after transmissions in the market. However, just like any other component in a vehicle, the Allison 3060 transmission requires proper wiring to function optimally. In this article, we will discuss the Allison 3060 wiring diagram, its components, and how to troubleshoot any wiring-related issues that may arise.
What is the Allison 3060 Transmission?
The Allison 3060 transmission is a six-speed automatic transmission that is designed for medium-duty commercial vehicles. It has a maximum gross vehicle weight rating (GVWR) of 28,000 pounds and can support engines up to 300 horsepower. This transmission has been widely used in school buses, shuttle buses, delivery trucks, and recreational vehicles.
The Allison 3060 transmission comes with a variety of features such as electronic controls, power take-off (PTO) provisions, and a lock-up torque converter. These features make the transmission efficient, durable, and easy to maintain.
Allison 3060 Wiring Diagram Components
The wiring system of the Allison 3060 transmission is composed of various components that work together to ensure the transmission functions optimally. These components include:
| Component | Description |
|---|---|
| ECM (Electronic Control Module) | The ECM is the brain of the transmission. It receives signals from various sensors and sends commands to the solenoids to engage or disengage the clutch. |
| Solenoids | The solenoids are responsible for controlling the engagement and disengagement of the clutches that transmit power to the gears. |
| Sensors | The sensors measure various parameters such as speed, temperature, and pressure, and send signals to the ECM to adjust the transmission accordingly. |
| Troubleshooting Connectors | The troubleshooting connectors are used to diagnose any wiring-related issues that may arise. |
Allison 3060 Wiring Diagram
The wiring diagram of the Allison 3060 transmission is a complex document that shows the connections between various components in the wiring system. The diagram is divided into sections that show the connections for different parts of the transmission.
The wiring diagram is used by technicians to diagnose any wiring-related issues that may arise. It is important to note that the wiring diagram may differ depending on the year, make, and model of the vehicle. Therefore it is important to use the correct wiring diagram when troubleshooting any issues.
Section 1: Power and Ground Connections
The first section of the wiring diagram shows the power and ground connections of the transmission. This section shows the connections for the battery, starter motor, alternator, and ground points. It also shows the fuses and relays that protect the electrical system of the vehicle.
If there is an issue with the power and ground connections, the transmission may not function properly. Therefore, it is important to check the connections in this section if there are any issues with the transmission.
Section 2: Shift Solenoid Connections
The second section of the wiring diagram shows the connections for the shift solenoids. The shift solenoids are responsible for engaging and disengaging the clutches that transmit power to the gears. If there is an issue with the shift solenoids, the transmission may not shift properly.
This section shows the connections for the shift solenoids, the diagnostic connector, and the ECM. Technicians use this section to diagnose any issues related to the shift solenoids.
Section 3: TPS and Output Speed Sensor Connections
The third section of the wiring diagram shows the connections for the throttle position sensor (TPS) and the output speed sensor. The TPS measures the position of the throttle pedal and sends a signal to the ECM to adjust the transmission accordingly. The output speed sensor measures the speed of the output shaft and sends a signal to the ECM to adjust the transmission accordingly.
If there is an issue with the TPS or the output speed sensor, the transmission may not function properly. This section shows the connections for these sensors, the diagnostic connector, and the ECM.
Section 4: Input Speed Sensor Connections
The fourth section of the wiring diagram shows the connections for the input speed sensor. The input speed sensor measures the speed of the input shaft and sends a signal to the ECM to adjust the transmission accordingly.
If there is an issue with the input speed sensor, the transmission may not function properly. This section shows the connections for the input speed sensor, the diagnostic connector, and the ECM.
