ok i think the trans is taking a crap I got these codes now too.... P0740.. TCC CKT Malfunction and P0743 Torque Converter CKT Electrical.... I've replaced the TCM and the input and output speed sensors.... changed the fluid no metal in the pan... maybe the valve body or the torque...? it doesn't start in gear so i'm sure it's not the netural switch... any ideas...

Check and make sure your trans fuses are good.
