Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Disconnect the battery to ensure safety during repairs.

2. Check Transmission Fluid

Locate the transmission dipstick.
Remove the dipstick, clean it, and reinsert it fully.
Remove the dipstick again and check the fluid level; it should be within the designated range.
If low, add the correct type of transmission fluid (Mercon LV).

3. Inspect Transmission Linkage

Locate the transmission linkage under the vehicle.
Visually inspect for any signs of damage or disconnection.
If damaged, remove the linkage using a socket set and replace it with a new one.

4. Examine Gear Selector

Remove the gear selector cover (if applicable) to access the gear selector mechanism.
Ensure that the gear selector moves freely and is not obstructed.
If it feels stiff or stuck, lubricate the mechanism or replace if necessary.

5. Check the Shift Cable

Locate the shift cable connected to the transmission.
Inspect for any fraying or signs of wear.
If damaged, disconnect the cable and replace it with a new one.

6. Reconnect Battery

Once repairs are completed, reconnect the battery terminal.
Ensure all connections are secure and there are no loose wires.
