Solution

1. Preparation

Gather tools and parts: OBD-II scanner, socket set, torque wrench, transmission fluid, funnel, and replacement torque converter (if necessary).
Ensure the vehicle is parked on a level surface and the engine is turned off.

2. Fluid Level Check

Sub-steps:
1. Locate the transmission dipstick or fill port.
2. Remove the dipstick, wipe it clean, and reinsert it.
3. Remove the dipstick again and check the fluid level; it should be within the specified range.
4. If low, add the appropriate transmission fluid type as specified in the owner’s manual.

3. Torque Converter Inspection

Sub-steps:
1. Disconnect the battery to ensure safety.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the transmission cover and inspect the torque converter for signs of damage or wear.
4. Check the mounting bolts and seals for looseness or leaks.

4. Torque Converter Replacement (if necessary)

Sub-steps:
1. Drain the transmission fluid using a drain pan.
2. Disconnect the torque converter from the transmission by removing the retaining bolts.
3. Carefully pull the torque converter out from the transmission.
4. Install the new torque converter by aligning it correctly and securing it with bolts to the specified torque setting (usually around 25-30 Nm, but confirm with the service manual).
5. Refill the transmission with the recommended fluid type.

5. Reassembly

Sub-steps:
1. Reconnect the battery.
2. Start the engine and allow it to reach operating temperature.
3. Check for leaks around the torque converter and transmission area.
