Solution

1. Preparation

• Gather tools and parts needed.
• Disconnect the negative battery cable to prevent electrical shorts.
• Ensure the vehicle is on a level surface and safely supported.

2. Inspect and Replace Transmission Range Sensor (TRS)

• Tools Required: Socket set, multimeter, torque wrench, cleaning solvent.
• Locate the TRS mounted on the transmission.
• Unplug the electrical connector from the TRS.
• Remove the TRS mounting bolts using the socket set.
• Carefully pull out the TRS from the transmission case.
• Inspect the sealing surface for debris and clean if necessary.
• Install the new TRS, ensuring it is seated properly.
• Torque the mounting bolts to the manufacturer’s specifications (typically around 8-10 Nm).
• Reconnect the electrical connector.

3. Check and Replace Transmission Fluid (if necessary)

• Tools Required: Fluid pump, transmission fluid, funnel.
• Remove the transmission fluid filler cap.
• Check fluid level with the dipstick; if low, add the appropriate type of transmission fluid (refer to the owner's manual).
• If fluid appears burnt or contaminated, drain the fluid from the transmission pan and replace it with new fluid.
• Reinstall the filler cap securely.

4. Reconnect Battery and Test

• Reconnect the negative battery cable.
• Start the vehicle and let it idle for a few minutes.
• Check for any leaks around the TRS area.
• Conduct a test drive to ensure smooth shifting and verify that the P0706 code does not return.
