how to resolve P0700 transmission code on Toyota RAV4 Fourth Generation (2013-2018)

Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

1. Remove the transmission dipstick and check the fluid level and condition; it should be bright red and clear.
2. If low, add the recommended ATF type (Toyota WS fluid).
3. If dirty or burnt, drain the transmission fluid using a pan to catch the old fluid.
4. Replace with new fluid and check the level again after running the engine for a few minutes.

3. Inspect and Repair Wiring

1. Locate the TCM, usually found in the engine compartment or under the dashboard.
2. Visually inspect the wiring harness for any frays, cuts, or corrosion.
3. Repair or replace any damaged wiring or connectors using electrical tape or heat-shrink tubing.

4. Replace Transmission Control Solenoid

1. Remove the transmission pan by loosening the bolts with a socket set.
2. Carefully lower the pan, allowing any remaining fluid to drain.
3. Remove the old transmission control solenoid(s) from their mounting location.
4. Install the new solenoid(s) and reassemble the transmission pan with a new gasket, tightening bolts to the manufacturer's torque specifications.

5. Reconnect Battery and Clear Codes

1. Reconnect the negative battery terminal.
2. Use the OBD-II scanner to clear the P0700 code and other related codes.
3. Start the engine and allow it to idle for a few minutes.
