Hello we have a 2001 Ml 430 and a slight problem with the gear engagement, after backing up when in reverse and going in to drive there is a delay that is anywhere from 3-6 seconds the warmer the car the longer the delay it seems.the ML does not have any slipping problems or transmission code stored but at times it will bang in to 2nd when slowing down for a turn and acelerating again. Does any one have any ideas what we might need to do ? Thanks
