Common Wiring Issues
The wiring in the 47RE transmission can sometimes cause problems that affect the transmission’s operation. Here are some of the common wiring issues:
Frayed or Broken Wires
Frayed or broken wires can cause a loss of signal or power to various components in the transmission. This can cause the transmission to shift erratically, or not shift at all. Inspect the wiring harness for signs of damage and repair or replace any damaged wires.
Corroded Connectors
Corroded connectors can cause poor connections and intermittent faults in the transmission system. Clean the connectors with electrical cleaner and replace any corroded connectors.
Bad Sensors or Solenoids
If the wiring is intact and the connectors are clean, the problem may be with a faulty sensor or solenoid. Test the sensors and solenoids with a multimeter and replace any that are faulty.
FAQ
What is the 47RE transmission?
The 47RE is a four-speed automatic transmission that was used in the second-generation Dodge Ram trucks from 1996-2002.
What is the function of the transmission control module?
The transmission control module (TCM) is a computer that controls the operation of the transmission, including the shifting and torque converter lockup.
What is a solenoid pack?
A solenoid pack is a group of solenoids that control the shifting of the transmission. The solenoids are electrically operated valves that open and close to control the flow of hydraulic fluid in the transmission.
What are the sensors in the 47RE transmission?
The sensors in the 47RE transmission include the speed sensor, throttle position sensor, and transmission temperature sensor. These sensors provide information to the TCM to control the operation of the transmission.
What is the wiring harness?
The wiring harness is a group of wires that connect the various components of the transmission and other systems in the vehicle. The wiring harness carries signals and power to and from the components.
