how to fix the P0700 transmission code on my Tesla Outback

Solution

1. Preparation

• Gather tools and parts required.
• Disconnect the negative battery terminal to ensure safety while working on electrical components.

2. Check Transmission Fluid

• Remove the transmission dipstick (if equipped) or drain the transmission pan.
• Inspect fluid condition; if fluid is dark or burnt, perform a transmission fluid change.
• If necessary, add the recommended transmission fluid (refer to owner's manual for specifications).

3. Repair Wiring and Connectors

• Visually inspect all wiring and connectors leading to the TCM.
• Clean any corrosion with electrical contact cleaner and ensure connections are tight.
• If damaged, replace any frayed or broken wires as needed.

4. TCM Testing and Replacement

• Use a multimeter to check voltage and continuity to and from the TCM.
• If the TCM fails the test, remove the old TCM by unscrewing it from its mount and disconnecting the wiring harness.
• Install the new TCM by connecting the wiring harness and securing it in place.

5. Reassembly and Fluid Replacement

• If fluid was drained, replace the transmission pan and secure it with the specified torque values.
• Reconnect the negative battery terminal.
• Fill the transmission with the appropriate fluid and check levels again.
