A method and system of controlling a drive-neutral-drive (D-N-D) shift in a multi-speed transmission. The method includes receiving a drive to neutral (D-N) shift request followed by a neutral to drive (N-D) shift request; initiating a drive to neutral (D-N) shift and determining an attained gear; determining a scheduled gear; determining if the scheduled gear is equal to the attained gear; and determining whether an off-going clutch for the drive to neutral (D-N) shift is in a hold state. The method further includes (I) aborting the drive to neutral (D-N) shift when (i) the scheduled gear is not equal to the attained gear and (ii) the off-going clutch for the (D-N) shift is in the hold state, or (II) completing a shift to neutral (N) when the off-going clutch for (D-N) shift is not in the hold state followed by shifting back drive (D).
