ABSTRACT:
A control system solves a drawback which would occur when a shift lever is returned from N-position to D-position (or any Forward position) after a previous shifting from D-position to N-position. The control system comprises a first control device for deriving and memorizing a suitable gear position of the transmission which is to be selected under a driving condition which has been assumed by the vehicle just before the return movement of the shift lever; and a second control device for forcing the transmission to take the memorized gear position upon completion of the return movement of the shift lever.
