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

Solution

1. Preparation

• Gather tools and parts necessary for the repair.
• Disconnect the vehicle battery to ensure safety while working on electrical components.

Tools Required:

• OBD-II scanner
• Socket set
• Torque wrench
• Transmission fluid pump
• Multimeter

2. Check and Replace Transmission Fluid

1. Locate the transmission dipstick (if equipped) or access the transmission pan.
2. Check the fluid level: Use the dipstick to ensure the fluid is at the correct level. If not, top off with the manufacturer-recommended transmission fluid.
3. Inspect fluid condition: If the fluid appears dark or burnt, proceed to replace it.
4. Drain the old fluid: Remove the transmission pan bolts and carefully lower the pan to drain the fluid.
5. Replace the filter: Remove the old transmission filter and install the new one, ensuring it is seated properly.
6. Reinstall the transmission pan: Clean the mating surfaces, replace the pan gasket as needed, and torque the bolts to the manufacturer’s specifications.

3. Inspect and Repair Wiring/Connectors

1. Examine the wiring harness: Check for frayed wires or broken connectors leading to the TCM.
2. Repair any damaged wiring: Use electrical tape or solder to fix any issues found.
3. Reconnect all connectors: Ensure all connections are secure and free of corrosion.

4. TCM Testing and Replacement (if necessary)

1. Perform a TCM check: Use a multimeter to test for proper voltage and ground at the TCM.
2. Replace the TCM: If faulty, remove the old TCM by unscrewing it from its mount, disconnecting the wiring harness, and installing the new unit.
3. Reprogram the new TCM: Follow the manufacturer’s instructions to ensure the new TCM is properly calibrated.
