Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Disconnect the vehicle's 12V battery for safety.

2. Update Firmware

Connect the vehicle to Wi-Fi.
Navigate to the software update section in the vehicle’s settings.
Download and install any available updates.

3. Transmission Fluid Check

Locate the transmission fluid dipstick (if applicable) or access the fluid fill port.
Remove the dipstick or fill cap and wipe it clean.
Reinsert it and check the fluid level; it should be within the marked range.
If low, add the appropriate transmission fluid recommended by the manufacturer.

4. Inspect Transmission Components

Visually inspect the transmission for any signs of leaks, cracks, or damage.
Check electrical connectors and wiring for corrosion or loose connections.
Tighten any loose bolts or fittings as per manufacturer specifications.

5. Battery Health Evaluation

Use a multimeter to test the battery voltage; it should be within the manufacturer’s specified range.
If the voltage is low, consider recharging or replacing the battery as needed.

6. Driving Mode Configuration

Check the vehicle settings to ensure it is not in a performance mode that could cause harsher shifts.
Switch to a standard or eco driving mode to test if the jerking continues.
