how to address P0700 transmission code for Tesla Model Y Current (2020-present)

Solution

1. Preparation

• Gather tools and ensure the vehicle is parked on a level surface with the parking brake engaged.
• Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Update Software

• Connect the vehicle to a Wi-Fi network.
• Navigate to the software update menu in the vehicle's settings.
• Follow on-screen instructions to update the vehicle's software if updates are available.

3. Inspect and Replace Transmission Fluid

• Remove the transmission fluid fill plug.
• Use a fluid extraction pump to remove old transmission fluid.
• Inspect the fluid; if it's contaminated or burnt, replace it.
• Refill the transmission with the recommended fluid type (Tesla recommends using their proprietary transmission fluid).
• Reinstall the fill plug and torque it to the manufacturer's specifications.

4. Repair or Replace Wiring/Connectors

• If any wiring or connector issues were found during diagnostics, carefully remove the damaged components.
• Replace with new connectors or wiring as necessary, ensuring secure connections.
• Use electrical tape or heat-shrink tubing to protect any exposed wires.

5. Clear Codes and Test Drive

• Reconnect the negative battery terminal.
• Use the OBD-II scanner to clear the P0700 code and any related codes from the TCM.
• Take the vehicle for a test drive to check for proper transmission operation and to ensure the code does not return.
