Trouble code P0740 – Dodge Ram P0740 code 1998

1998 dodge 1/2 ton sport model, one owner vehicle.

Transmission rebuilt February 2023.  Every 6 to 8 weeks since rebuild engine light on dash indicates P0740 code, which indicates torque convertor clutch solenoid. Trans fluid is fine, no erratic shifting, no high RPM, truck has less than 4K miles since transmission rebuilt. Each time the code comes on I take the vehicle back to the repair shop and they install a new solenoid. Then six to eight weeks later same symptoms occur/repeat. Any other suggestions? Or Is time to replace the torque convertor or just have the transmission shop start with fresh rebuild?
