I have a small problem I need help with. Sometimes a few days ago I engaged reverse in As200 and nothing happened. For a scary moment i thought the gearbox is dead.. then I put it back to Park and engaged Reverse and immediately it engaged. Its an on and off problem.. what I notice is when i put it to Park, after a few seconds there is a "click"... if i put reverse I after that "click" its fine, Reverse engages easily. I checked the oil its fine, is there something I need to check or adjust on the selector or something,.. like I said its on and off this problem..
