Disconnect the battery to prevent electrical shorts during repair.

2. Check and Replace Transmission Fluid

Tools Required: Torque wrench, funnel, fluid pump, catch basin.
Sub-steps:
1. Remove the transmission dipstick or fill plug to check fluid level.
2. If fluid is low or has a burnt smell, drain the old fluid using a catch basin.
3. Replace with the manufacturer's recommended transmission fluid, ensuring the correct type and amount.
4. Reinstall the dipstick or fill plug and torque to specifications.

3. Inspect and Replace Transmission Range Sensor

Tools Required: Socket set, multimeter.
Sub-steps:
1. Locate the transmission range sensor on the transmission assembly.
2. Disconnect the electrical connector from the sensor.
3. Remove the sensor using a socket set, taking note of any gaskets or seals.
4. Test the new sensor with a multimeter to ensure it meets specifications.
5. Install the new sensor, ensuring proper alignment and securing it with the correct torque.
6. Reconnect the electrical connector.

4. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and check for any warning lights on the dashboard.
