Solution

1. Preparation

Tools and Equipment: Gather an OBD-II scanner, multimeter, socket set, and basic hand tools.
Safety Precautions: Ensure the vehicle is on a flat surface, engage the parking brake, and wear safety goggles.

2. Address TCM Issues

Sub-step 1: If codes indicate TCM failure, disconnect the vehicle battery to avoid short circuits.
Sub-step 2: Remove the TCM, typically located under the dashboard or near the transmission.
Sub-step 3: Inspect the TCM for water damage or burnt components.
Sub-step 4: If necessary, replace the TCM with a new or refurbished unit, ensuring it is compatible with your RAV4.

3. Repair Transmission Fluid Issues

Sub-step 1: If fluid is low, add the correct type of transmission fluid (e.g., Toyota ATF WS) and check for leaks.
Sub-step 2: If fluid is dirty, perform a transmission fluid change, including a filter replacement if applicable.

4. Replace Faulty Solenoids

Sub-step 1: If solenoids are found to be defective, remove the transmission pan.
Sub-step 2: Replace the faulty solenoid(s) with new parts, ensuring to torque bolts to manufacturer specifications.
Sub-step 3: Reinstall the transmission pan and refill with the appropriate transmission fluid.
