Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

Locate the transmission dipstick.
Remove the dipstick, wipe it clean, reinsert, and then remove it again to check the fluid level.
If low, add the recommended transmission fluid (Honda ATF DW-1) until the proper level is reached.

3. Inspect the Shift Linkage

Remove any covers or panels obstructing access to the shift linkage.
Visually inspect the linkage for damage or disconnection.
Reconnect or replace any damaged components as necessary.

4. Test the Brake Light Switch

Locate the brake light switch near the brake pedal.
Disconnect the switch connector and use a multimeter to check for continuity when the pedal is pressed.
Replace the brake light switch if it fails to operate correctly.

5. Check Fuses

Locate the fuse box and identify the fuses related to the transmission control module.
Inspect for any blown fuses and replace them with the correct amperage rating.

6. Reconnect Battery and Test

Reconnect the battery terminals.
Start the vehicle and attempt to shift into gear.
If the issue persists, further diagnostics may be needed.
