Abstract:
A control system for a vehicular automatic transmission whose operation is automatically controlled for selecting and establishing a speed ratio from a plurality of speed ratios in response to condition of a vehicle set in a drive range, said control system creating a neutral condition if said vehicle is stationary with a brake being operated and an accelerator for an engine being turned off while said transmission is set in said drive range;wherein: said control system comprises a brake operation detector, which detects operational condition of said brake of said vehicle, and an output rotation detector, which detects rotational speed of an output member of said transmission; and even though said brake operation detector detects that said brake is being operated, if said output rotation detector detects that said output member is rotating, then said control system terminates said neutral condition and sets a predetermined speed ratio.
