Abstract
A manual shift lever for an automatic transmission has a park position and a plurality of drive positions. The shift lever is detented into each position and has both a brake/transmission shift interlock (BTSI) and an ignition interlock which independently inhibit shifting from the park position prior to predetermined operating inputs, such as manipulating the ignition key and/or the brake pedal. A bell crank connected with the interlocks provides the inhibiting structure. To limit the operator input force on the bell crank, a lost motion structure is provided between an operator button on the shift lever handle and an actuator rod and pin which engage the bell crank.
