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

Solution

1. Preparation

• Gather necessary tools and parts.
• Park the vehicle on a level surface and ensure the engine is turned off.
• Disconnect the battery to prevent electrical shorts.

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, 10mm socket, fluid catch pan.
• Remove the transmission fluid pan using a 10mm socket, allowing old fluid to drain completely into a catch pan.
• Inspect the pan for metal shavings or debris. If found, further inspection of the transmission may be necessary.
• Replace the transmission filter if applicable, following manufacturer specifications.
• Reinstall the pan and torque the bolts to the specified torque value (usually around 8-10 ft-lbs).
• Refill the transmission with fresh fluid, ensuring to use the correct type specified in the owner's manual (generally Continuously Variable Transmission (CVT) fluid for Subaru).

3. Inspect and Repair Electrical Connections

• Tools Required: Multimeter, wire brush, electrical contact cleaner.
• Inspect the wiring harness leading to the TCM and transmission solenoids.
• Use a multimeter to check for continuity and proper voltage at the connectors.
• Clean any corrosion or dirt from the connectors using electrical contact cleaner and a wire brush.
• Repair or replace any damaged wires or connectors as necessary.

4. Replace Transmission Control Module (if necessary)

• Tools Required: 10mm socket, ratchet, torque wrench.
• If diagnostics indicate a faulty TCM, remove the old module by disconnecting the wiring harness and unbolting it using a 10mm socket.
• Install the new TCM by reversing the removal process and ensuring all connections are secure.
• Torque bolts to manufacturer specifications.

5. Reconnect Battery and Clear Codes

• Reconnect the battery and start the vehicle.
• Use the OBD-II scanner to clear the P0700 code and any other related codes.
• Test drive the vehicle to ensure the issue has been resolved.
