4. If fluid is burnt or dirty, drain the transmission fluid using a drain pan and replace it with new fluid.
Tools Required:
- Transmission fluid pump
- Drain pan
- Funnel

3. Inspect and Replace Transmission Range Sensor

Sub-steps:
1. Locate the transmission range sensor on the transmission.
2. Disconnect the wiring harness from the sensor.
3. Remove the sensor using the appropriate socket and replace it with a new one.
4. Reconnect the wiring harness and ensure it is secure.
Tools Required:
- Socket set
- Torque wrench

4. Inspect Throttle Position Sensor

Sub-steps:
1. Locate the throttle position sensor on the throttle body.
2. Disconnect the electrical connector from the sensor.
3. Use a multimeter to test the resistance across the sensor terminals.
