Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to ensure safety while working on electrical components.

2. Check and Replace Transmission Fluid

Tools Required:
- Socket set
- Transmission fluid pump
- Fluid catch pan
Sub-steps:
1. Locate the transmission fluid dipstick or drain plug.
2. If necessary, remove the drain plug and allow old fluid to drain into the pan.
3. Inspect the old fluid for metal shavings or burnt smell; if present, further inspection of the transmission may be needed.
4. Reinstall the drain plug (if removed) and fill with the manufacturer-recommended transmission fluid using the pump until the proper level is reached.

3. Inspect and Adjust Transmission Linkage

Tools Required:
- Wrench set
Sub-steps:
1. Locate the transmission linkage and inspect for any signs of damage or misalignment.
2. If misaligned, adjust the linkage according to the manufacturer specifications.
3. Ensure all bolts are tightened to the specified torque values as per the service manual.

4. Check and Replace Brake Switch (if necessary)

Tools Required:
- Multimeter
- Screwdriver set
Sub-steps:
1. Locate the brake switch, usually found near the brake pedal.
2. Use a multimeter to test the switch for continuity when the brake pedal is pressed.
3. If faulty, disconnect the old switch and install a new one, ensuring it is adjusted correctly to engage when the pedal is pressed.

5. Reconnect Battery and Test

Reconnect the vehicle's battery.
Start the engine and check for any error codes or warning lights.
Test the shifting from park to drive to verify the issue has been resolved.
