how to troubleshoot P0700 code in Tesla Outback 4th Generation (2010-2014)

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the battery to prevent electrical shorts during repairs.
• Ensure the vehicle is on a level surface and secure it with wheel chocks.

2. Fluid Change

• Drain Fluid: Remove the drain plug (if equipped) and allow the old transmission fluid to completely drain into a waste container.
• Replace Filter: If applicable, remove the transmission filter and replace it with a new one.
• Refill Transmission Fluid: Use the manufacturer-recommended transmission fluid. Fill through the dipstick tube or designated fill port until the correct level is reached.
• Torque Specifications: Ensure drain and fill plugs are tightened to the manufacturer’s recommendations.

3. Wiring Inspection and Repair

• Inspect Harness: Check the wiring harness for any signs of wear, fraying, or damage.
• Repair or Replace: If any damaged wires are found, repair using heat-shrink tubing and soldering or replace the harness if necessary.
• Reconnect: Ensure all connectors are secure and properly seated.

4. TCM Diagnostics

• Reprogram TCM: If necessary, perform a reprogramming of the TCM using a compatible diagnostic tool.
• Test Drive: After reprogramming, take the vehicle for a test drive to ensure proper shifting and operation.
