The DTC P0740 is for a "Problem in Lock-up Control System". This code means that there is most likely a problem within the transmission. It could also possibly be caused by a wiring issue or a control module. It would be best to have a certified mechanic take a look at the vehicle in person and perform necessary diagnostics on the code to determine exactly what should be done.
