Abstract
A shift mechanism for the transmission of a vehicle in which a locking arm is provided to prevent shifting of the shift lever, the locking condition of the locking arm being controlled by a magnetic latch which includes a permanent magnet that produces a magnetic flux to hold the arm in locked position. A coil is provided in the magnetic latch to produce a magnetic flux that opposes the magnetic flux produced by the permanent magnet to destroy the holding force of the permanent magnet when a brake switch is closed to energize the coil thus permitting the locking arm to be moved to an unlocked position and the shift lever to be shifted.
