2005 GMC ENVOY 4.2L. I have a P0740 code on it?

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. Check it out on youtube.

1995 Gmc Sonoma is having trans problems

Sounds like a bad transmission. Once the oil in your transmission warms up it becomes a thinner viscosity allowing your clutch plates to slip
