Solution

1. Preparation

Gather tools and parts needed for this repair.
Tools Required: OBD-II scanner, socket set, torque wrench, fluid pump, clean rags.
Safety Warnings: Ensure the vehicle is in a safe and stable position, preferably on a lift or jack stands. Disconnect the battery before starting work on the electrical components.

2. Update Firmware

Check the vehicle’s software version using the touchscreen interface.
If an update is available, schedule a service appointment or perform the update via the Tesla app.

3. Check Transmission Fluid

Remove the transmission fill plug and use a fluid pump to extract some fluid.
Inspect the fluid condition; it should be clean and reddish in color.
If the fluid is dark or burnt, proceed to replace the transmission fluid.

4. Replace Transmission Fluid (if necessary)

Drain the old transmission fluid by removing the drain plug.
Allow the fluid to completely drain into a suitable container.
Replace the drain plug and torque it to the manufacturer's specification (typically around 25-30 Nm).
Fill the transmission with new fluid using the pump until it reaches the proper level, as indicated by the fill plug.

5. Inspect and Replace Components (if needed)

Check the motor mounts and transmission mounts for any signs of wear or damage.
If any mounts are damaged, replace them with OEM parts.
Reassemble any components that were removed during inspection.
