Vauxhall Signum autamatic gearbox misbehaving

Car: Vauxhall Signum
Variant: 1.9 diesel design
Model Year: 2006
Categories: Running Rough, Starting & Power Loss
My Signum (automatic) runs quite well but sometimes when it is asked to change gear quickly it judders,it also sometimes goes to change gear but does not find a gear and the engine races. I sometimes have to pull over and turn the ignition off and it seems to reboot and become normal again.

The cruise control does not work after the gearbox problem occurs but returns when the ignition has been turned on and off.
