When the ign is turned on and or engine is started the VCM computer checks things out.
If it finds a problem it may turn on check engine light and set a code for the problem found.
In you case.
Code P0740 is telling you there is a open or short to ground in the TCC solenoid circuit.
You need to repair the circuit or TCC solenoid.
