Solution

1. Preparation

Tools Required: Socket set, torque wrench, transmission jack, OBD-II scanner, fluid catch pan, basic hand tools.
Disconnect the battery ground cable to avoid electrical shorts.
Raise the vehicle securely on jack stands and ensure it is stable.

2. Remove the Transmission

Sub-steps:
1. Drain the transmission fluid by removing the transmission pan.
2. Remove the transmission pan and filter to access the transmission.
3. Disconnect the shift linkage and any electrical connectors.
4. Unbolt the transmission from the engine using the appropriate socket size.
5. Support the transmission with a transmission jack and carefully lower it from the vehicle.

3. Remove the Torque Converter

Sub-steps:
1. Once the transmission is removed, locate the torque converter which is mounted on the flexplate.
2. Unbolt the torque converter from the flexplate (typically 3-4 bolts).
3. Slide the torque converter off the input shaft of the transmission.
4. Inspect the torque converter for any signs of damage or wear.

4. Install the New Torque Converter

Sub-steps:
1. Place the new torque converter onto the input shaft of the transmission, ensuring it is properly seated.
2. Bolt the torque converter to the flexplate using the original bolts, tightening to the manufacturer's torque specifications (typically around 30-35 ft-lbs).
3. Reinstall the transmission by aligning it with the engine and securing it with the bolts.

5. Reassemble and Refill Transmission Fluid

Sub-steps:
1. Reinstall the transmission pan with a new gasket and tighten the bolts to the specified torque (typically around 10-15 ft-lbs).
2. Reconnect the shift linkage and electrical connectors.
3. Fill the transmission with the appropriate fluid type (Mopar ATF +4 recommended) through the dipstick tube.
4. Start the engine and let it idle, checking for leaks and ensuring the torque converter engages properly.
