ABSTRACT:
An improved motor vehicle transmission locking device for use with automatic transmissions and manual transmissions. The improved locking device utilizes a solenoid which is used to lock into a notch formed on an existing transmission parking shaft to lock the transmission in the parked position. The solenoid is mounted inside of the transmission case and may be activated by an encoder/decoder circuit and may also be activated by a simple switch or lock switch hidden out of sight on the motor vehicle.
A modified form of the invention replaces the existing transmission parking shaft with a split shaft and positions the solenoid between the two pieces of the split shaft. This modification then accomplishes the enabling and disabling of the transmission when activated by either the encoder/decoder circuit or by other switching circuits positioned on, and hidden from a thief that may try to steal the motor vehicle.
