Solution

1. Preparation

Gather necessary tools and replacement parts.
Disconnect the negative battery terminal to prevent electrical shock.
Allow the vehicle to cool if recently driven.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set.
Carefully lower the pan and drain the old transmission fluid completely.

3. Remove Torque Converter

Remove the bell housing bolts connecting the torque converter to the engine.
Carefully pull the torque converter away from the engine flywheel.
If necessary, use a torque converter puller tool for ease of removal.

4. Inspect and Replace Components

Inspect the torque converter for wear or damage; replace if necessary.
Check the flywheel for any cracks or excessive wear.
Replace transmission fluid filter if applicable, ensuring to use the manufacturer-recommended filter.

5. Reinstall Torque Converter

Align the torque converter with the engine flywheel and carefully slide it back into position.
Reinstall the bell housing bolts and tighten them to the manufacturer's specified torque values.

6. Refill Transmission Fluid

Reinstall the transmission pan with a new gasket.
Fill the transmission with new, manufacturer-specified fluid through the dipstick tube.
Start the engine and cycle through the gears to ensure the fluid circulates.

7. Final Checks

Check for leaks around the transmission pan and torque converter.
Reconnect the negative battery terminal.
