Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues during repairs.

2. Drain and Replace Transmission Fluid

Use a socket set to remove the transmission drain plug and drain the old fluid into a suitable container.
Remove the transmission pan (if applicable) and replace the filter.
Install a new gasket and reattach the pan, tightening bolts to the manufacturer's torque specifications (typically 8-10 Nm).
Fill the transmission with new fluid as per the manufacturer’s specifications (usually ATF specified by BMW).

3. Inspect and Replace Torque Converter

Remove the drive shaft or any components obstructing access to the torque converter.
Unbolt the torque converter from the flex plate using a socket set.
Carefully remove the torque converter from the transmission.
Install the new torque converter by ensuring it is fully seated and bolted securely to the flex plate.

4. Reassemble and Reconnect Components

Reinstall any components removed during the process, ensuring all connections are secure.
Reconnect the battery and check fluid levels again.
