ABSTRACT:
A device for locking the automatic transmission of an automobile is described to deter theft. The device locks either the outer manual lever, the detent lever or the manual valve. Once locked a spring keeps the transmission locked unless unlocked. The unlocking mechanism can be mechanical, electromagnetic or vacuum. The lines which control the unlocking are armoured to prevent tampering. Severing of these lines keeps the vehicle locked and immovable even if the motor is started.
