Okay, 50 pm'* a day is enough, when all I can ever do is tell people to post the problem. Don't EVER PM someone for technical advice on this forum. This applies to every member. POST your problem for others to be able to help you.
I saw this topic earlier, but I'm very busy trying to cook a meal, and I have sick people in the house, so I chose not to go into depth at the time.
Disconnect the steering wheel connector on the back of the stereo. It'* the one off to the side by itself. Does the problem go away?
Your torque converter is trying to engage, but can't hold. Check your trans fluid for color and level. Consider getting it scanned.
The clicking is normal operation. Ignore it. Do not disconnect it or your car will blow up. You're lucky to be alive. We had 4 members of this forum die just yesterday from disconnecting a vapor recovery purge solonoid. (joking on the blowing up part, it is normal to click).
Further information on the TCC unlock surging issue is needed. Was the cruise engaged? If so, it may be normal operation depending on the incline. If the load on the engine is too high (cruise or your foot ask too much and the TPS senses a change in voltage beyond it'* normal point), the TCC will disengage by design.
