Solution

1. Preparation

Gather the necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Ensure the vehicle is on a level surface and securely lifted.

2. Remove Transmission Pan

Drain the transmission fluid into a clean container.
Remove the bolts securing the transmission pan using a socket set.
Carefully lower the pan and replace the transmission filter if necessary.

3. Remove Torque Converter

Unbolt the torque converter from the flex plate using a socket set.
Remove any necessary components obstructing the torque converter (e.g., exhaust parts).
Pull the torque converter away from the transmission carefully.

4. Inspect and Replace

Inspect the torque converter for any signs of damage or wear.
If defective, replace the torque converter with a new or refurbished unit.
Ensure the new torque converter is properly seated before reinstallation.

5. Reassemble

Reattach the transmission pan using a new gasket and torque bolts to manufacturer specifications (typically 10-12 Nm).
Refill the transmission with the appropriate type and amount of fluid.

6. Final Checks

Reconnect the battery.
Start the engine and allow it to warm up while checking for leaks.
Perform a test drive to ensure proper operation.
