Components of the 47RH wiring diagram
The 47RH wiring diagram consists of various components that are interconnected through the transmission’s electrical system. These components include:
- Transmission Control Module (TCM)
- Solenoids
- Pressure Sensors
- Temperature Sensors
- Wiring Harnesses
Each of these components plays a crucial role in the proper functioning of the transmission.
Transmission Control Module (TCM)
The Transmission Control Module (TCM) is the brain of the transmission. It is responsible for interpreting the signals from the various sensors and solenoids and determining the appropriate gear ratio and shift points for the transmission.
The TCM is connected to the transmission solenoids and pressure sensors through various wiring harnesses, which transmit the electrical signals between the components.
Solenoids
The solenoids are electro-magnetic devices that control the flow of transmission fluid through the various valves in the transmission. There are several solenoids in the 47RH transmission, each with a specific function.
The solenoids are controlled by the TCM, which sends electrical signals to them to open and close the valves as required.
Pressure Sensors
The pressure sensors in the transmission measure the hydraulic pressure of the transmission fluid. There are several pressure sensors in the transmission, which provide feedback to the TCM on the pressure in various parts of the transmission.
The TCM uses this information to determine the appropriate shift points and gear ratios for the transmission.
Temperature Sensors
The temperature sensors in the transmission measure the temperature of the transmission fluid. There are several temperature sensors in the transmission, which provide feedback to the TCM on the temperature in various parts of the transmission.
The TCM uses this information to adjust the transmission’s shift points and operating parameters to compensate for changes in temperature.
Wiring Harnesses
The wiring harnesses are the electrical connections between the various components of the transmission. There are several wiring harnesses in the 47RH transmission, which transmit the electrical signals between the TCM, solenoids, pressure sensors, and temperature sensors.
