Ford PX Ranger 3.2D P0741 Fault: Ongoing Issues After $11,500 Repairs on 6R80 Transmission

I own a Ford PX Ranger 3.2D equipped with a 6R80 transmission and have accumulated over 120,000 km of driving. Recently, I've been consistently encountering the P0741 diagnostic code, which indicates a pressure sensor circuit malfunction in the transmission. I've already invested $11,500 in repairs to resolve this issue, including: - Replacement of the billet torque converter - Installation of a new transmission cooler system - Thermal bypass upgrade - New lead frame assembly - Refurbished valve body and solenoids - Full internal rebuild of the transmission Despite these extensive efforts, the P0741 code persists. I've reached out to Ford support multiple times, but have not received a clear or actionable solution. I'm seeking community input on potential root causes or troubleshooting steps that might resolve this issue. Any insights into possible wiring issues, sensor calibration problems, or transmission control module (TCM) faults would be greatly appreciated. Thanks for any help or advice!
