Operation

Neutral

  • Each interlock pin is in the groove of each shift rod because no shift rod is operating.

1st/2nd shifting

  • Movement of the 1st/2nd shift rod forces interlock pins A and C out of the 1st/2nd shift rod grooves, and the reverse shift rod and 3rd/4th shift rod are locked. In addition, interlock pin C forces interlock pin E out via interlock pin D, and the 5th/6th shift rod is locked.
