A shift control system is provided for an automatic transmission having, connected in series, a secondary shifting unit, capable of being shifted between a high speed stage and a low speed stage, and a primary shifting unit which provides plural speed stages including a reverse speed stage. The secondary shifting unit can be set to the high speed stage upon a shift into reverse. The shift control system is equipped with a reverse range detector for detecting a shift from neutral to reverse range, a vehicle stop detector for detecting that vehicle is stopped, and a high speed stage command device for setting the secondary shifting unit at the high speed stage when, subsequent to a shift of the primary shifting unit into reverse, the vehicle is determined by a signal from the vehicle stop detector to have substantially stopped.
A shift control system for an automatic transmission in a vehicle, the automatic transmission including, connected in series, a secondary shifting unit having a high speed stage and a low speed stage and a primary shifting unit providing plural speed stages including neutral and a reverse speed stage, wherein the secondary shifting unit can be shifted to the high speed stage upon establishing the reverse speed stage, said shift control system comprising:
A shift control system for an automatic transmission in a vehicle powered by an engine, the automatic transmission including, connected in series, a secondary shifting unit, connected to the engine and having a high speed stage and a low speed stage, and a primary shifting unit providing plural speed stages including neutral and a reverse speed stage, wherein the secondary shifting unit can be shifted to the high speed stage upon establishing the reverse speed stage, said shift control system comprising:
A shift control system for an automatic transmission in a vehicle, the automatic transmission having neutral and forward ranges and an output shaft which is allowed to rotate in a reverse direction at a predetermined speed stage in the forward range but is prevented from rotation in the reverse direction at a different speed stage in the forward range, the shift control system comprising:
A shift control system for an automatic transmission in a vehicle powered by an engine, the automatic transmission having neutral and forward ranges and an output shaft which is connected to the engine and is allowed to rotate in a reverse direction at a predetermined speed stage set in the forward range but is inhibited from rotation in the reverse direction at a different speed stage in the forward range, the shift control system comprising:
