Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, fluid catch pan.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent electrical short circuits.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick; check fluid level and condition.
2. If fluid is low, add the recommended type of transmission fluid (Toyota WS).
3. If fluid is dirty or burnt, proceed to drain and replace the fluid.
4. Use a fluid catch pan to drain the old transmission fluid from the transmission pan.
5. Replace the transmission filter if applicable, following manufacturer specifications.
6. Refill with fresh transmission fluid and check for leaks.

3. Inspect and Repair Transmission Linkage

Sub-steps:
1. Visually inspect the transmission linkage for wear or damage.
2. Adjust the linkage as necessary to ensure proper alignment.
3. Lubricate any moving parts in the linkage mechanism if needed.

4. Replace Faulty Transmission Solenoids

Sub-steps:
1. Locate the transmission solenoids by removing the transmission pan.
2. Disconnect the electrical connectors from the solenoids.
3. Remove the old solenoids and install new ones, ensuring they are secured properly.
4. Reassemble the transmission pan and refill with transmission fluid.

5. Test Torque Converter

Sub-steps:
1. During a test drive, monitor engine RPMs relative to vehicle speed to check for converter lock-up.
2. If the converter is malfunctioning, replace it following manufacturer guidelines.
