Solution

1. Preparation

Gather all necessary tools and parts.
Disconnect the battery to prevent electrical shorts.
Allow the vehicle to cool if it has been running.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set, allowing the fluid to drain completely.
Clean the transmission pan and magnet using a suitable solvent.

3. Replace Torque Converter

Disconnect the transmission from the engine by removing the bell housing bolts.
Remove the torque converter by sliding it off the input shaft.
Install the new torque converter by aligning it properly with the input shaft and pushing it into place until it seats fully.

4. Reinstall Transmission

Reattach the transmission to the engine, ensuring all bell housing bolts are properly tightened to the manufacturer's torque specifications.
Reinstall the transmission pan with a new gasket and torque the bolts to the specified value.

5. Refill Transmission Fluid

Refill the transmission with the recommended fluid type through the dipstick tube.
Start the engine and let it idle while cycling through the gears to circulate the fluid.

6. Final Checks

Reconnect the battery.
Clear any error codes from the OBD-II scanner.
Conduct a road test to ensure proper operation.
