Solution

1. Preparation

Tools Required: OBD-II scanner, transmission fluid dipstick, floor jack, jack stands, torque wrench, and safety goggles.
Raise the vehicle using a floor jack and secure it with jack stands.

2. Check Transmission Fluid

Sub-steps:
1. Remove the transmission fluid dipstick.
2. Wipe it clean, reinsert, and check the fluid level.
3. If low, top up with the recommended ATF (Toyota Type T-IV).
4. If dirty or burnt, consider a transmission fluid change.

3. Inspect Torque Converter and Components

Sub-steps:
1. Remove the transmission inspection cover if applicable.
2. Visually inspect the torque converter for any signs of damage.
3. Check the mounting bolts for tightness (specification: 30 Nm).
4. Inspect the flexplate for cracks or wear.
5. Ensure the torque converter is properly seated.

4. Perform Stall Test

Sub-steps:
1. Start the engine and allow it to reach operating temperature.
2. Shift into drive while holding the brake pedal.
3. Gradually apply the throttle until the engine RPM stabilizes.
4. Note if the RPM rises significantly above the normal range (indicates a slipping converter).

5. Replace Torque Converter (if necessary)

Sub-steps:
1. Disconnect the negative battery terminal.
2. Drain the transmission fluid.
3. Remove the transmission from the engine (requires support and possibly removing cross members).
4. Disconnect the torque converter from the transmission.
5. Install the new torque converter, ensuring it fully engages.
6. Reassemble all components and refill with fresh ATF.
