How can the torque converter be locked while the vehicle is stopped? Serious question, I don't know what is special about this auto transmission that would allow that.
Maybe not "locked", I probably said it wrong. One way or the other there is no power going to the transmission when the car stops, I am not sure if it reduces line pressure or what, but there is no power. As soon as you let off the brake you will feel a small jolt and then there is power again. If you quickly let off the brake then mash on the gas you will get a real jolt, and its not refined at all. I noticed this right away in the 2014 Jetta, this was not noticeable at all in the 2013 that she had before (was totaled). So something changed when they introduced the 1.8T in 2014. Anyway at the first service they did an update and that lurch has gone away.
