So my problem is that my car goes into manual mode fine. Drives in it along as I don't get on the throttle much. But when I do and I left off wot it kicks me back in drive and won't go back into manual mode. I have to slow down to a complete stop and it goes back in manual mode. This had been this way along as I owned it and other 5at owners say they don't have this problem. Anyone have a solution
