Solution

1. Preparation

Tools Required: Socket set, torque wrench, OBD-II scanner, multimeter, jack and jack stands, transmission fluid, torque converter seal kit.
Raise the vehicle using a jack and secure it on jack stands.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Remove Transmission Pan

Sub-steps:
1. Drain the transmission fluid into a clean container by removing the drain plug or pan bolts.
2. Remove the transmission pan by unscrewing the bolts and carefully prying it off.
3. Inspect the pan for metal shavings or debris that could indicate internal damage.

3. Remove Torque Converter

Sub-steps:
1. Disconnect the transmission from the engine by removing the bolts securing the bell housing.
2. Carefully slide the transmission away from the engine to access the torque converter.
3. Remove the torque converter from the transmission input shaft by unbolting it.

4. Inspect and Replace

Sub-steps:
1. Inspect the old torque converter for signs of wear or damage.
2. If necessary, replace the torque converter with a new or remanufactured unit.
3. Install a new torque converter seal to prevent fluid leaks.

5. Reassemble and Refill

Sub-steps:
1. Reinstall the torque converter, ensuring it is properly seated on the input shaft.
2. Reconnect the transmission to the engine and secure it with the bell housing bolts.
3. Reattach the transmission pan and refill with new transmission fluid as specified by the manufacturer.

6. Final Checks

Reconnect the negative battery terminal.
Clear any error codes from the vehicle’s computer and conduct a road test.
