Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface, engage the parking brake, and disconnect the battery.

2. Fluid Change

Tools Required: Socket set, transmission fluid pump, transmission fluid (refer to owner's manual for specifications), fluid catch basin.
Drain the old transmission fluid by removing the drain plug, and allow it to fully drain into the catch basin.
Replace the drain plug and torque it to the manufacturer's specifications.
Use the transmission fluid pump to refill with new transmission fluid through the fill port.

3. Software Update

Tools Required: Laptop with Tesla software update capability or OBD-II scanner compatible with Tesla vehicles.
Connect the laptop or scanner to the vehicle's OBD-II port.
Check for available software updates for the TCM and apply any necessary updates as per manufacturer instructions.

4. Solenoid Replacement (if necessary)

Tools Required: Socket set, torque wrench, replacement solenoids.
Remove the transmission pan by unbolting it and draining any remaining fluid.
Access the solenoids and remove the faulty ones by unbolting them.
Install new solenoids and torque to the manufacturer's specifications.
Reinstall the transmission pan with a new gasket and torque to specifications.

5. Final Checks

Reconnect the battery and start the vehicle.
Allow the engine to reach operating temperature and check for leaks around the transmission pan and solenoids.
Test drive the vehicle to confirm that the shifting issue has been resolved.
