how to fix P0700 transmission code on Tesla Outback 4th Generation (2010-2014)

Solution

1. Preparation

• Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, fluid catch pan, funnel.
• Safety Warnings: Disconnect the battery before working on electrical systems; allow the engine to cool if checking transmission fluid.

2. Address Fault Codes

• Sub-steps:
  1. Use the OBD-II scanner to clear the P0700 code and any additional codes.
  2. Drive the vehicle for a short distance to see if the code reappears.

3. Transmission Fluid Service

• Sub-steps:
  1. Locate the transmission dipstick (if equipped) or the fill plug.
  2. Remove the dipstick/fill plug and check fluid level.
  3. If low, add the recommended transmission fluid (refer to owner’s manual for specifications).
  4. If fluid is discolored or burnt, perform a complete fluid replacement.
     • Drain the old fluid by removing the drain plug and allow it to fully drain into a catch pan.
     • Replace the transmission filter if applicable.
     • Refill with new fluid using a funnel.

4. Inspect and Repair Electrical Connections

• Sub-steps:
  1. Visually inspect the transmission wiring harness and connectors for damage.
  2. Use a multimeter to check for continuity and proper voltage at the TCM and solenoids.
  3. Repair or replace any damaged wiring or connectors as necessary.

5. Test Transmission Components

• Sub-steps:
  1. Test the resistance of each transmission solenoid against manufacturer specifications.
  2. Replace any solenoids that are outside of spec.
  3. Reinstall all components and connectors securely.
