Hi all - sorry if this is covered elsewhere. Have a 2011 2.8 CRD Grand Voyager Auto, ran fine until had a few issues with the battery being drained (ran out of diesel/wife problem) changed battery. Ever since when slowing down to a stop, the car will "slam" into first gear. It's as if it is chaning down too early? Have changed all fuel filters and also auto box oil (allthough the garage did not change the filter). Any thoughts?
