When I did the original video, it wasn't THAT noticeable, though when hearing it in person with my head in the engine bay, as well as in the interior of the car, it was quite noticeable, especially after a long drive. As many have described it, it sounded quite similar to that of a playing card, in amongst a spinning bicycle wheel.

I believe after having heard many of the videos, as well as the numerous discussions about it on the forums here, I encountered mine, just as it was starting to act up, before it went completely full blown.

Call me crazy, but I heard a noise when I filmed the original video, and even to this day, I still hear that same noise when I replay the video. All I know is that before I replaced the TCT, there was a loud, noticeable noise, and after I replaced the TCT, the sound disappeared, and I have yet to encounter it since, and that was roughly about 5,000 miles ago.

TCT noise is prominent over any noise in the car, including a running engine.

If an s2k is on its way to my shop with a bad TCT, I can hear the TCT noise down the street before I even hear the car.

That's actually EXACTLY how mine would sound while sitting idle at a stoplight, after a decent drive around town, it just wasn't THAT loud when it was start up for the first time each day. Not quite sure why exactly that was, because you'd imagine that it'd be making that noise 24/7, but mine seemed to want to do it on its own schedule, and talk about embarrassing, sitting in traffic with a beautiful car such as the S2000, only to have it making that kind of commotion!

For the future, all TCT videos should be taken with the hood closed, 10 feet from the car, if you REALLY want to hear the noise. Underhood noise blends it out when taken too close. In the vid I posted, the camera is in the drivers seat.

Haha, well I'm going to keep my fingers crossed that I'm not going to have to do another video about the TCT anytime soon, but if by chance I ever do, I'll be sure to remember your tips!
