Abstract

A gimbal-type automotive transmission shifter and gear lockout is provided comprising a gear selecting shift lever; a pivotable shift lever carrier; and a stationary base for mounting the transmission shifter in an automotive vehicle. The shift lever and shift lever carrier are pivotable about first and second generally orthogonal axes, respectively. The shift lever is pivotable relative to the carrier about the first axis and the carrier is pivotable relative to the base about a second axis. Appropriate linkage is provided for translating these pivotable movements to the transmission for selecting a desired transmission drive ratio. A gear lockout is provided by a first gate disposed on the base. A detent is mounted for reciprocal movement with respect to the base. Biasing means is provided for biasing the detent into engagement with the base. The biasing means thereby prevents entry of the detent into the first gate and thus provides a positive first lockout for at least one gear position. Means for manually actuating the detent comprising a pushbutton or pull ring-type lockout actuator is provided for overcoming the biasing means and aligning the detent with the first gate to pr…
