The main throttle is NOT "fly-by-wire". The TCS (a seperate secondary throttle plate behind the main throttle) is normally open and only closes as TCS is engaged. This is a much different system than the earlier 4 cylinder TCS systems. There is a kickdown cable that can be adjusted using a special tool. However, I have found that the factory procedure do not seem to work as well at the "seat of the paints" approach. The adjustment is near the throttle lever. You may have to remove a shield for the throttle cable assembly to access it. It has been a while since I have done one, but I seem to remember that the adjustment was right there. I did one once and had a major problem with it. My District Service Manager referred me to another dealer whose Service Manager had had a simular problem. They had replace a trans for other reasons and the new one would not shift correctly. They replace the trans again with the same results. (Note the first replacement fixed the original complaint). Finally, they stepped outside the box and played with the adjustment and where able to get the trans to shift as expected. I was also able to fix my customers car as well with the adjustment. >It's unlikely to make a difference but, just in case, it's a UK model.
