Where is the torque converter clutch solenoid located?

The torque converter clutch solenoid will not cause this problem, I think you are looking for the #1 control solenoid. Also, when you put the car in drive does the gear selector for that gear light up? If not, this can be he problem as well. If so, I would check the fuses in if okay replace the shift lever position switch. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.
