Solution

1. Preparation

Tools Required:
- Jack and jack stands
- Socket set
- Torque wrench
- Transmission fluid pump
- OBD-II scanner
- Screwdrivers
- Pliers
Sub-steps:
1. Park the vehicle on a level surface and engage the parking brake.
2. Disconnect the negative battery terminal to prevent electrical shorts.
3. Raise the vehicle using a jack and secure it with jack stands.

2. Remove Transmission

Sub-steps:
1. Remove the driveshaft by unbolting the universal joint and sliding it out of the transmission.
2. Disconnect any electrical connectors and linkages connected to the transmission.
3. Unbolt the transmission crossmember and lower the transmission slightly.
4. Unbolt the bellhousing from the engine, ensuring all bolts are removed.
5. Carefully lower the transmission and remove it from the vehicle.

3. Remove Torque Converter

Sub-steps:
1. With the transmission removed, locate the torque converter attached to the flexplate.
2. Unbolt the torque converter from the flexplate, taking note of the bolt positions.
3. Carefully slide the torque converter off the input shaft and remove it from the transmission housing.

4. Install New Torque Converter

Sub-steps:
1. Lubricate the new torque converter's input shaft and O-ring with transmission fluid.
2. Slide the new torque converter onto the input shaft, ensuring it is fully seated and engages the pump.
3. Reinstall the torque converter bolts to the flexplate and torque to manufacturer specifications (typically around 30-35 ft-lbs).

5. Reinstall Transmission

Sub-steps:
1. Lift the transmission back into position, aligning it with the engine bellhousing.
2. Bolt the transmission back to the engine, ensuring all bolts are tightened to specifications.
3. Reinstall the transmission crossmember and driveshaft.
4. Reconnect any electrical connectors and linkages removed earlier.

6. Refill Transmission Fluid

Sub-steps:
1. Use a transmission fluid pump to refill the transmission with the appropriate fluid type (typically Mercon LV for this model).
2. Start the engine and cycle through the gears to circulate the fluid.
3. Check the fluid level and add more if necessary.
