Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, torque wrench, fluid pump, transmission jack.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shorts.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts using a socket set and carefully lower the pan to drain fluid.
Inspect the fluid for metal shavings or discoloration.

3. Remove Torque Converter

Disconnect the transmission from the engine by removing the mounting bolts.
Support the transmission with a transmission jack.
Remove the torque converter bolts (typically 3-4) from the flex plate.
Carefully slide the torque converter out of the transmission.

4. Inspect Torque Converter and Replace if Necessary

Check the torque converter for signs of wear or damage (cracks, leaks).
If damaged, replace the torque converter with a new one (ensure it matches OEM specifications).

5. Reinstall Torque Converter

Slide the new torque converter into place, ensuring it is seated correctly.
Reattach the torque converter bolts to the flex plate and torque to manufacturer specifications (usually around 30 lb-ft).
Reconnect the transmission to the engine securely.

6. Refill Transmission Fluid

Use a fluid pump to refill the transmission with the correct type of transmission fluid (check owner’s manual for specifications).
Replace the transmission pan and tighten bolts to manufacturer specifications (usually around 8-10 lb-ft).

7. Final Checks

Reconnect the battery.
Start the engine and allow it to idle. Check for leaks and ensure the transmission fluid is at the correct level.
Test drive the vehicle to ensure proper operation of the torque converter.
