Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the vehicle is parked on a level surface, and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket wrench.
Carefully lower the pan to drain the fluid completely.
Inspect the fluid for debris or metal shavings.

3. Remove Torque Converter

Remove the transmission assembly as needed (refer to service manual for specific removal instructions).
Disconnect the torque converter from the transmission by removing the bolts securing it to the flexplate.
Carefully pull the torque converter away from the engine.

4. Inspect and Replace

Inspect the removed torque converter for signs of wear, damage, or internal failure.
Clean any debris from the transmission case where the converter mounts.
Install the new torque converter, ensuring proper alignment and secure it to the flexplate with the specified torque (refer to service manual for torque specifications).

5. Reassemble and Refill

Reinstall the transmission assembly, ensuring all connections and mounts are secure.
Replace the transmission pan and refill with new transmission fluid (using the type specified in the owner’s manual).
Reconnect the negative battery terminal.
