how do I fix the P0700 transmission code on my Tesla Outback 5th Generation (2015-2019)

Solution

1. Preparation

• Gather tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

• Remove the transmission dipstick (if applicable).
• Wipe the dipstick clean, reinsert it, and remove it again to check the fluid level.
• If the fluid is low, add the manufacturer-recommended transmission fluid.
• If the fluid is dirty or burnt, proceed to a fluid change (see step 3).

3. Change Transmission Fluid

• Tools Required: Socket set, fluid pump, transmission fluid.
• Remove the transmission pan bolts and carefully lower the pan.
• Drain the old transmission fluid into a suitable container.
• Replace the transmission filter (if applicable).
• Clean the transmission pan and replace the gasket as necessary.
• Reinstall the pan with the correct torque specification (typically around 10-12 ft-lbs).
• Fill the transmission with new fluid using the recommended type.

4. Inspect and Repair Wiring

• Visually inspect the wiring harness and connectors leading to the TCM and transmission.
• Repair or replace any damaged wiring or corroded connectors as needed.

5. Reconnect Battery and Clear Codes

• Reconnect the battery terminals and ensure they are tight.
• Use the OBD-II scanner to clear the P0700 code and any other transmission-related codes.

6. Test Drive

• Take the vehicle for a test drive under various conditions to ensure normal operation and shifting.
