P0741 Fault in 2010 Ford F150XL 4.6L with 6R80 Transmission - No Torque Converter Response After Rebuild

Model: 2010 F150XL Fault Code: P0741 Posted: 2018-11-12 14:06

I've been experiencing repeated stalling issues for over a year and a half, with no resolution even after visits to the dealership. The vehicle has consistently thrown lean-related and generic diagnostic codes. Recently, a P0741 code appeared, indicating a torque converter pressure issue. I have already had the transmission serviced at 90,000 miles due to a minor leak, replaced the torque converter, FCC solenoids, and rebuilt the entire transmission unit. Despite these efforts, the torque converter still shows no response, and the vehicle remains unresponsive during deceleration.

Inspect the wiring harness connected to the transmission for any shorts, open circuits, or corrosion that could interfere with signal transmission.

I'm currently verifying all electrical connections and suspecting a faulty valve body or potential TCM (Transmission Control Module) issue. The TCC solenoid has been replaced twice in the past, but it still does not function properly, which may point to deeper electronic or mechanical failure.
