how do I fix the P0700 transmission code on my Toyota Camry Seventh Generation (2012-2017)

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent any electrical shorts.

2. Check Transmission Fluid

• Tools Required: Transmission fluid pump, funnel
• Remove the transmission dipstick and check the fluid level and condition.
  • If fluid is low, add the specified type of transmission fluid (e.g., Toyota ATF WS).
  • If fluid is dirty or burnt, proceed to a fluid change.

3. Replace Transmission Fluid and Filter

• Tools Required: Socket set, fluid catch pan, new transmission filter, new transmission fluid
• Remove the transmission pan by unbolting it and draining the old fluid into a catch pan.
• Replace the transmission filter:
  • Remove the old filter and install the new one, ensuring it is seated properly.
• Reinstall the transmission pan and torque bolts to manufacturer specifications (typically around 8-12 ft-lbs).
• Fill the transmission with new fluid through the dipstick tube, following the manufacturer’s recommendations.

4. Inspect and Repair Wiring

• Tools Required: Multimeter, electrical connectors
• Check for any damaged wiring or corroded connectors leading to the transmission control module.
  • Repair or replace any damaged wiring or connectors as necessary.

5. Test Speed Sensors

• Tools Required: Multimeter
• Disconnect the input and output speed sensors.
• Use a multimeter to test for proper voltage and signal output according to manufacturer specifications.
  • Replace any malfunctioning sensors.
