why does my Tesla Outback keep throwing P0700 transmission code

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, multimeter, transmission fluid, funnel, torque wrench.
• Safety Warnings: Ensure the vehicle is on a level surface and the engine is off before starting work.

2. Addressing Transmission Fluid Issues

• Sub-step 1: If low, add the correct type of transmission fluid as specified in the owner’s manual.
• Sub-step 2: If fluid condition is poor (dark or burnt smell), drain and replace the fluid.
• Sub-step 3: Check for leaks in the transmission system and repair as necessary.

3. Inspecting Wiring and Connections

• Sub-step 1: Disconnect the battery before starting work on electrical components.
• Sub-step 2: Visually inspect the wiring harness leading to the transmission for any signs of wear or damage.
• Sub-step 3: Use a multimeter to check continuity and resistance in the wiring and connectors.

4. Testing the Transmission Control Module

• Sub-step 1: Reconnect the battery and use the OBD-II scanner to check for TCM-related error codes.
• Sub-step 2: If codes indicate a faulty TCM, consider reprogramming or replacing the module as needed.

5. Final Steps

• Sub-step 1: Clear all error codes using the OBD-II scanner.
• Sub-step 2: Perform a test drive to ensure that the transmission operates smoothly without triggering the P0700 code again.
