DTC P0740 Torque Converter Clutch (TCC) Enable Solenoid Control Circuit
Circuit Description
The torque converter clutch (TCC) solenoid valve is an electrical device that is used with the torque converter clutch pulse width modulation (TCC PWM) solenoid valve in order to control TCC apply and release. The TCC solenoid valve attaches to the transmission case assembly extending into the pump cover. The TCC solenoid valve receives ignition voltage through the ignition 0 voltage circuit. The powertrain control module (PCM) controls the solenoid by providing the ground path on the TCC solenoid valve control circuit. The PCM monitors the throttle position sensor voltage, the vehicle speed, and other inputs in order to determine when to energize the TCC solenoid valve.
When the PCM detects a continuous open, short to ground or short to power in the TCC solenoid valve circuit, then DTC P0740 sets. DTC P0740 is a type B DTC.

2005 GMC Envoy. What sensor do I need to change for temperature gauge please?
scan the ECT if it reads wrong most time the 17 year old thermostat is bad. stuck open, missing or those crazy fail safe stat gone wild.
ect 180 to 200f is normal .
if not thermostat is first. I used and IR gun to measure the stat hosing to see if its bad, 1minutes work,
most times the gauge never fails so we do 1simple test to prove that.
scan the PCM is first.
never seen a STaT good 17 year old,
had one that told near all day to hit 180f>?
when old that do nasty things, even stick closed and warp HEADS
why risk that, attack the stat.
Where is the fuel shutoff switch?
battery has a full charge and battery connections all good? There is no fuel shut-off. engine cranking, you have spark at the plugs and fuel injector pulse? At the fuel pump, gray wire is voltage, black wire is ground. Engine cranking, if you have good voltage and ground at the fuel pump but no fuel pump action, suspect the fuel pump.
How to recalibrate the liftgate module to open the lifegte eitherway on 2005 gmc envoy xuv
not sure if this is what you're looking for but hope it helps..
Important: The driver information center (DIC) will display the message See Manual - Tailgate anytime a learn is required except after the installation of a new regulator. When a module is not learned, or in a window fault state, only the window remains functional.
1.Activate the window up switch using the key cylinder or overhead console switch and maintain switch activation for 2 seconds after the window has stalled in the fully closed position.
WARNING
Important: The window may be in any position to start the re-learn, but the up operation must be performed first.
2.Activate the window down switch and maintain switch activation for 2 seconds after the window has stalled in the fully open position.
