Please help, 03 Lightning with trans codes

[Bullitt66]

Just got a lightning from a friend, the truck was stored for about 1 year, had a bad supercharger, already replaced it and runs fine, but then I got two codes

P0740 Ford Torque Converter Clutch Solenoid Circuit
P0743 Ford Torque Converter Clutch Solenoid Circuit Electrical

trans oil level is fine, just changed the fluid after I got the codes, checked the harness but only found a big plug from the drivers side, is there any other plug around the trans? or should I remove the pan? What more could it be?

Thanks

You'll have to remove the pan and check those solenoids to see if they are still good.

Check your fuses and wiring first. Make sure the wires aren't touching the exhaust or being pinched between the head and the firewall.
