Hello! Can you please try pressing the throttle for longer and seeing if the vehicle still does not move? It is normal that there is a lag between the application of the throttle and the movement of the vehicle. This can be due to two reasons 1) The torque converter slips (seen as Tconv slip). In the screenshot you can also see the T conv out RPM is only 10 and so it is expected that the vehicle does not move forward. This is similar to a vehicle in real life, even if you slam the throttle there will be a finite lag before the vehicle starts moving. 2) This lag might seem longer than usual because your simulation might not be running at Real Time. This means that even though you feel that you have been pressing the keyboard key for a long time, in simulation time, it is too low (and still within the lag period). From my experience, pressing the key for about 1 second simulation time is enough to get the vehicle moving. If you still face issues after pressing the key for longer, then there might be some problem and we can try looking at it together :)
