Abstract
Abstract An automobile antitheft device having a locking rod that locks the parking lock pawl of an automatic transmission in a position where it engages and locks a parking pawl gear. The locking rod is spring biassed so that it automatically becomes engaged when the automatic transmission is placed into Park. A separate lever is actuated and used to withdraw the locking rod from locking the pawl. The locking rod is provided with a transverse groove to prevent unlocking of the transmission except when the transmission is in Park. The device is also provided with an electric switch and regulator which is operatively coupled to the locking rod as is electrically connected between the fuel injectors and the car's computer.

Claim 1
Independent Claim
140 words
A security device for an automatic vehicle transmission having a plurality of gears operatively mounted to a chasis consisting of, combination, (a) said chasis having means for mounting said device to said automatic transmission, (b) bushing means attached to said chasis in which a locking rod is slidably mounted, (c) said locking rod attached to an actuator rod and being constructed to engage a locking pawl, (d) said locking pawl pivotally attached to the chasis and having a downwardly extending element designed to fit into a groove in a gear of said automatic transmission thereby locking said gear in a non-operative position, (e) means for releasing said locking rod and locking pawl consisting of a spring which biases the locking rod into a non locking position thereby releasing the locking pawl from engagement with the gear of the automatic transmission.
