Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to prevent electrical short circuits.
Raise the vehicle using a hydraulic lift or jack stands for access to the transmission.

2. Drain Transmission Fluid

Place a drain pan under the transmission pan.
Remove the transmission pan bolts and carefully drop the pan to drain the fluid.
Inspect the magnet for metal shavings and clean the pan.

3. Remove and Inspect Torque Converter

Remove any components obstructing access to the torque converter (such as the transmission crossmember or exhaust components).
Unbolt the torque converter from the flexplate.
Carefully pull the torque converter away from the transmission and inspect it for cracks or damage.

4. Replace Torque Converter (if necessary)

If the torque converter is damaged, replace it with a new unit.
Ensure the new torque converter is properly seated before bolting it to the flexplate.
Torque the flexplate bolts to the manufacturer’s specifications (typically around 35-40 ft-lbs).

5. Reassemble and Refill Transmission Fluid

Reattach the transmission pan using a new gasket and torque the bolts to the manufacturer’s specifications (usually 10-12 ft-lbs).
Refill the transmission with new fluid as per specifications (typically Mercon LV or equivalent).
Reconnect the negative battery terminal.
