SMG Gearboxes

Hi,

Its worth noting that on the SMG Box
the rod selector is not spring loaded for
obvious reasons.

In a manual box it is and the detent is set to neutural

Hence when the SMG actuator selects a new
gear, any wear or misalingment on
selection will cause hesitant selctions as
the ECU will detect a] resistance, and b]
greater pressure.

As the selector fork then starts to engage and slide
in to the correct position the pressure is reduced
back to normal, and the resistance point has been
passed, so the gear is then slected.

Hesitant selection is another factor of clutch slur.

Small particules of metal will be evident in the
Gearbox oil due to the misalingment rubbing.

This also explains in part why there is no Gearbox
slur upon a Manual Car, which has almost the same
Gearbox and clutch arrangement.

Regards,

The Gorilla.
