Additional alerts that may provide additional information may accompany this alert .A reduction in vehicle fuel economy may also occur when the fault is present. The transmission control module has detected that the torque converter clutch failed to apply. This system failsafe logic disables the torque converter clutch when this condition is present. This results in a higher than normal engine RPM's during higher vehicle cruising speeds and reduced fuel economy. now my car is still driving fine. i took it to auto zone to put the computer on it and it read this code P0741 which gives this Torque Converter Clutch Circuit Performance or Stuck Off, which indicates that the vehicle's computer commanded the torque converter clutch to lock up, but it is failing to do so. i took it to our ford dealer ship and he stated oh yes you need a whole new transmission which is 7200$ do you want to pay now .... Im shocked that my car would need a new transmission... i have seen recalls for Torque Converter for the fusion .. but my vin is not showing this recall is there anyone else experiencing this

I am the original single owner of a 2019, paid-off, gas Fusion with less than 54,000 miles, a spotless maintenance record, and no accident history. The vehicle suffered a sudden, instantaneous total loss of motive power. The loss of electric power steering assist and loss of power brake assist while driving through a live intersection with no warning lights or prior engine shuddering nearly caused a severe, life-threatening, or even fatal collision. The vehicle was removed from the intersection by physically pushing it with the assistance of other passing motorists and local police. I immediately called and requested towing services through the manufacturer. Services arrived 2 hours later. They started the car with no issue and drove it onto the tow truck. No engine lights or warning lights were present; the vehicle did not stutter or shake, and the vehicle had a 1/4 tank of gasoline. The vehicle was delivered directly to the Dealership. After it stalled and once it was removed from the intersection, no attempt was made to restart the vehicle until the towing service arrived. The dealership has had the vehicle for 2 weeks and claims they cannot diagnose the cause; there are no active diagnostic codes, and they have not been able to replicate the failure regarding this potentially fatal electrical shutdown. It is completely unacceptable and dangerously irresponsible for a dealership to hold a vehicle for 2 weeks, then suggest "picking it up, add some gas" simply because they haven't found any issues and "it should be fine." I cannot, in good conscience and out of protection of myself, my family, and other motorists, continue operating a vehicle that exhibits life-threatening intermittent failures.
