Locate the transmission dipstick (if applicable) or the fill plug.
Remove the dipstick or fill plug and check the fluid level.
If low, add the appropriate type of transmission fluid (consult the owner’s manual for specifications).
Ensure the fluid is clean; if dirty, proceed to fluid replacement.

3. Inspect and Adjust Transmission Linkage

Visually inspect the transmission linkage for any signs of damage.
If misaligned, adjust the linkage according to manufacturer specifications.
Tighten any loose bolts or connections to ensure proper operation.

4. Replace Faulty Components

If error codes indicate a faulty brake switch or other components, replace them.
For fluid leaks, replace any damaged seals or hoses identified during inspection.

5. Reconnect Battery and Test

Once repairs are made, reconnect the battery.
Start the vehicle and check for any warning lights.
Test the transmission by attempting to shift through all gears.
