Hello evryone that helped! I went to the shop yesterday and they checked the u-joint front shaft and it doesn't have a play(I was with them too).Only if you hold the shaft and turn it will have a 1/3 or 1/4 play either way. Also, the CV has play up,down,and sideways a little.They said it's normal to have a clearance but they mentioned about the gearbox inside the TC might have something to do with drivetrain vibrations. And the solenoid which they pointed out is that long tubular or cylindrical black (plastic?) on the rear right side of the T-case might need replacement. The mechanic drove the car(with me) for 2 miles and found nothing abnormal. Is this right? I mean I still feel a slight vibrations in the steering and dirvers side or the in the rear passenger floor(heard) and also in the hood. I have a 4 button switch(includes auto4W).
