Good day y’all. I’ve been having problems with my transmission. As soon as I I engage the vehicle in drive, the car has a hard jerk. But in motion it seems not to transmit to any other gear, not even when engaged in tiptronic mode. I scanned it and got an internal electrical check of component y3/8y4 vgs error. Please how can I solve this problem

 

Check y4 circuit and replace vgs if all tests fine
