Solution

1. Preparation

Gather tools and materials: OBD-II scanner, socket set, fluid pump, transmission fluid, rags.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical issues while working.

2. Transmission Fluid Change

Drain Old Fluid:
- Locate the transmission drain plug (if equipped) or remove the transmission pan.
- Allow the old fluid to drain completely into a catch pan.
Replace Filter:
- If applicable, remove the transmission filter by unscrewing or unclipping it.
- Install the new filter according to manufacturer specifications.
Clean the Pan:
- Thoroughly clean the transmission pan and magnet (if present) to remove metal shavings or debris.
Reinstall the Pan:
- Replace the pan gasket (if applicable) and reinstall the transmission pan.
- Torque the bolts to the manufacturer's specifications.
Add New Fluid:
- Use a fluid pump to add the recommended type and amount of transmission fluid through the dipstick tube.

3. Adjust Transmission Range Sensor

Locate the Range Sensor:
- Find the transmission range sensor mounted on the transmission.
Test and Adjust:
- Check the voltage output using a multimeter.
- Adjust the sensor position if necessary, following manufacturer specifications.
Reconnect Battery:
- Once all adjustments are complete, reconnect the battery.
