Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is turned off.
Gather tools and materials: OBD-II scanner, socket set, torque wrench, transmission fluid, funnel, and rags.
Disconnect the negative battery terminal to avoid electrical issues.

2. Check Transmission Fluid

Remove the transmission dipstick and wipe it clean.
Reinsert and remove the dipstick to check the fluid level; it should be within the marked range.
If low, add the appropriate type of Honda ATF (Automatic Transmission Fluid) through the dipstick tube using a funnel.
Inspect the fluid condition; if dark or burnt, a transmission fluid change may be needed.

3. Inspect Transmission Linkage

Locate the transmission linkage under the vehicle.
Visually inspect for any signs of wear, misalignment, or damage.
Adjust the linkage if necessary, ensuring it is properly connected to the transmission.

4. Test Brake Light Switch

Locate the brake light switch near the brake pedal.
Ensure it is functioning correctly by pressing the pedal and checking if the brake lights illuminate.
If faulty, replace the brake light switch.

5. Replace Transmission Range Sensor (if necessary)

Disconnect the electrical connector from the range sensor.
Remove the securing bolts and carefully take out the range sensor.
Install the new sensor and secure it with bolts, reconnecting the electrical connector.

6. Reconnect Battery and Test Drive

Reconnect the negative battery terminal.
Start the vehicle and test the transmission by shifting into reverse and ensuring it engages properly.
Test drive the vehicle to confirm proper operation in all gears.
