My 2006 DB9 decided today to start having spasms. The car starts up fine but when I press any of the transmission buttons it throws up a whole list of issues. If I press the button again the engine shuts down. I have a link to the video beloe, if anyone is able to help! The messages are:

Gearbox Pos. Not Avail
Traction Control Temporary Off
Gearbox Fault Service Required
Reduced Engine Perform
Emission System Service Required
DSC Service Required
Brake Failure Stop Safely (when brake is pressed)

I had the transmission fluid changed 2 weeks ago along with the pan filter and bits, car was driving perfect until this just happened.
