Solution

1. Preparation

• Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, transmission fluid, and safety glasses.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shorts.

2. Inspect and Replace Transmission Fluid

• Sub-steps:
  1. Remove the transmission fluid dipstick and check the fluid level.
  2. If low, add the recommended transmission fluid specified in the owner’s manual.
  3. If the fluid is dark or has a burnt smell, drain and replace it:
     • Locate the transmission fluid drain plug, remove it, and allow the old fluid to drain completely.
     • Reinstall the drain plug and torque it to the manufacturer’s specification.
     • Fill the transmission with new fluid through the dipstick tube, using a funnel.

3. Check Transmission Control Module Connections

• Sub-steps:
  1. Locate the Transmission Control Module (usually near the transmission).
  2. Disconnect the electrical connector carefully.
  3. Inspect for corrosion or damage and clean the terminals if necessary.
  4. Reconnect the harness ensuring it clicks into place.

4. Test Transmission Range Sensor

• Sub-steps:
  1. Locate the transmission range sensor.
  2. Disconnect the electrical connector.
  3. Using a multimeter, check for continuity across the sensor terminals according to the service manual specifications.
  4. If the sensor is faulty, replace it with a new one.

5. Reconnect Battery and Clear Codes

• Reconnect the battery after repairs are completed.
• Use the OBD-II scanner to clear any stored trouble codes.
