RE: tr6 gearbox/overdrive

Regarding overdrive and the transmission switches:  To verify that the
switches work, or determine when they engage/disengage try this.  In a
quiet location, turn the ignition to the on position without starting
the car.  Engage the overdrive switch.  Shift into various gears and
listen.  You can hear the relay switching.  TURN OFF THE KEY.
