Just wondering if anyone has this same problem - It appears when the torque converter is locked up above 80km/h and you are coasting with no throttle at all the tacho is all over the show, jumps around between about 1300 and 1500rpm. Both my VP and VS calais do it - though the VS does it worse. A prime example is when going 100km/h with the cruise on and then tapping the brake pedal to disengage it and while the speed is dropping the revs are bouncing around - but the car doesnt shake or jurk or anything.
Also the VS does sometimes slow down much faster than it should when coasting, as if its in 3rd gear instead of Drive.
Could the torque converter be on its way out or is this a common problem?
