Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, transmission fluid, drain pan, safety goggles, gloves.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to prevent electrical shorts.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission drain plug or pan bolts to drain the fluid completely.
Inspect the fluid for metal shavings or debris which could indicate internal damage.

3. Remove Torque Converter

Tools Required: Socket set, torque wrench, transmission jack.
Remove the transmission from the vehicle by unbolting it from the engine, and disconnecting the electrical connectors and shift linkage.
Carefully lower the transmission using the transmission jack.
Unbolt the torque converter from the flywheel and gently pull it away from the transmission.

4. Inspect Torque Converter

Check the torque converter for any signs of damage such as cracks or leaks.
Inspect the fins inside the converter for deformation or wear.
If the torque converter is damaged, proceed to replace it.

5. Install New Torque Converter

Tools Required: Torque wrench.
Align the new torque converter with the transmission, ensuring it seats properly.
Bolt the torque converter to the flywheel to the manufacturer's specified torque settings.
Reattach the transmission to the engine and secure it with the appropriate bolts.

6. Refill Transmission Fluid

Replace the transmission pan and tighten bolts to the manufacturer's specifications.
Refill the transmission with the correct type and amount of fluid as specified in the owner's manual.

7. Reconnect Battery and Test

Reconnect the battery.
Start the vehicle and let it idle, checking for any leaks.
Perform a test drive to ensure proper function of the torque converter and smooth shifting.
