how to fix P0700 code in my Toyota Corolla E140 (2006-2013)

Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

• Tools Required: Transmission fluid pump, funnel, socket set, torque wrench.
• Steps:
  1. Locate the transmission dipstick or fill plug.
  2. Remove the dipstick or fill plug and check the fluid level. If low, add the appropriate type of ATF (typically Toyota Type T-IV).
  3. If the fluid is dirty or burnt, drain the transmission fluid by removing the drain plug.
  4. Replace with new, clean transmission fluid and secure the drain plug to the manufacturer’s torque specifications.

3. Inspect and Replace TCM

• Tools Required: Diagnostic tool, socket set, multimeter.
• Steps:
  1. If the diagnostic checks indicate a faulty TCM, locate the TCM under the dashboard or near the transmission.
  2. Disconnect the electrical connectors carefully.
  3. Remove the TCM from its mounting bracket.
  4. Install the new TCM by reversing the removal process, ensuring all connectors are securely attached.
  5. Reconnect the negative battery terminal.
