A shift control device includes a forward and reverse shifting mechanism for selectively drivingly connecting and disconnecting forward and reverse gear trains to and from a vehicle drive wheel. In shifting the transmission from reverse through neutral and into drive, the forward and reverse shift mechanism remains operatively engaged with the reverse gear train until the transmission is shifted from neutral into drive, at which time the forward and reverse shift mechanism moves into operative engagement with the forward gear train. In shifting from drive through neutral into reverse, the forward and reverse shift mechanism remains operatively engaged with the forward gear train until the transmission is shifted from neutral into reverse, at which time the forward and reverse shift mechanism is moved into operative engagement with the reverse gear train. Accordingly to another embodiment, if the forward and reverse shift mechanism becomes improperly engaged with one of the gear trains, this improper engagement is detected, and the forward and reverse shift mechanism is automatically adjusted by a slight amount to permit proper engagement with the gear train. |
