Solution

1. Preparation

Tools Required: Socket set, torque wrench, jack and jack stands, transmission fluid, OBD-II scanner, fluid catch pan, screwdriver set, pry bar.
Disconnect the negative battery terminal to ensure safety during the procedure.
Raise the vehicle using a jack and securely support it with jack stands.

2. Remove Transmission Components

Sub-steps:
1. Drain the transmission fluid into a catch pan by removing the drain plug.
2. Remove the transmission pan by unscrewing the bolts with a socket wrench.
3. Disconnect the transmission cooler lines and electrical connectors from the transmission.
4. Unbolt the torque converter from the flex plate using the appropriate socket.
5. Remove any mounting bolts securing the transmission to the engine and the crossmember.

3. Remove the Torque Converter

Sub-steps:
1. Carefully slide the transmission away from the engine, ensuring the torque converter comes off with the transmission.
2. If necessary, use a pry bar to gently separate the torque converter from the transmission bell housing.
3. Remove the torque converter and inspect the input shaft for damage.

4. Install New Torque Converter

Sub-steps:
1. Align the new torque converter with the transmission input shaft and carefully slide it into place.
2. Rotate the torque converter until it locks into the transmission (you should feel it click into place).
3. Secure the torque converter to the flex plate with bolts, tightening them to the manufacturer-specified torque (check repair manual for torque specifications).

5. Reassemble Transmission

Sub-steps:
1. Reinstall the transmission onto the engine, ensuring it aligns properly with the engine mounts.
2. Reattach the transmission cooler lines and electrical connectors.
3. Reinstall the transmission pan and refill with new transmission fluid.
4. Reconnect the negative battery terminal.
