Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off.
Disconnect the battery to prevent electrical shorts.

2. Drain Transmission Fluid

Remove the transmission pan bolts using a socket set.
Carefully lower the pan to drain fluid into a container.
Inspect the pan for metal shavings or debris.

3. Remove the Torque Converter

Remove the transmission bell housing bolts using a socket set.
If necessary, remove the drive shaft and exhaust components for access.
Support the transmission with a jack and lower it slightly to access the torque converter.
Disconnect the torque converter from the flex plate by removing the bolts.

4. Install New Torque Converter

Position the new torque converter onto the input shaft of the transmission.
Rotate the converter to ensure it engages properly with the pump.
Secure the torque converter to the flex plate with the appropriate torque specification (usually 30-40 ft-lbs).

5. Reassemble Transmission

Lift the transmission back into place and secure it with bell housing bolts.
Reinstall the transmission pan and torque to specification (usually 10-15 ft-lbs).
Reconnect any previously removed components (drive shaft, exhaust).

6. Refill Transmission Fluid

Refill the transmission with new fluid as per manufacturer specifications (typically ATF+4 for Ram 1500).
Start the engine and allow it to reach operating temperature while checking for leaks.
