My LR3 is 2007, it is showing check engine light as amber color, whenever am driving it **** at a point i.e. like it was suddenly released to speed. It then shows transmission problem on the dash, then the transmission error logo comes up on the dash. When i park, switched the car off then switched on again it wont come up again until i start driving fast again. It comes up often also when am on a bad road and the vehicle shakes alot. Kindly advise
