Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the engine to cool down if it has been running.

2. Check and Adjust Transmission Fluid Level

Sub-steps:
1. Start the engine and let it idle until reaching normal operating temperature.
2. Shift through all the gears and then return to Park.
3. Remove the dipstick, wipe it clean, and reinsert it fully.
4. Remove the dipstick again and check the fluid level; it should be between the "Full" and "Add" markings.
5. If low, add the recommended automatic transmission fluid (ATF) type (Mercon LV) through the dipstick tube until the correct level is achieved.

3. Adjust Transmission Linkage

Sub-steps:
1. Locate the transmission linkage where it connects to the transmission.
2. Loosen the adjustment bolt using a socket set.
3. Move the linkage to align it properly according to the manufacturer's specifications.
4. Tighten the adjustment bolt to the specified torque (generally 12-15 ft-lbs).
5. Test the gear shifter for smooth operation through all gears.

4. Check for Leaks and Secure Components

Sub-steps:
1. Inspect all connections and seals for any signs of fluid leaks.
2. Tighten any loose bolts or screws associated with the transmission assembly.
3. Replace any damaged seals or gaskets as necessary.
