A common fault with the Dualogic with no certain quick fix. When I had my 2009 GP Dualogic it would give the same error on cold, damp days. Running the engine until the temperature gauge reached just beyond the 1/4-mark usually got things going again. If you ever have to move the vehicle during this time, you'll probably find that it's stuck in gear and the problem is that the Dualogic system can't select neutral.

My working theories were:

Damp in the electrics somewhere that dries out when the engine warms up; or

Temperature related viscosity changed in a fluid either in the servos or the gearbox itself, the gearbox sensors sensing too much resistance and preventing operation until the fluid warmed up and thinned.


Get any error codes read to see what they say, but mine never gave anything other than generic WTF? codes with this problem.

Hi, Sounds as if the HP pump isn't starting to pump when you open the driver's door. Can you hear the pump the instant you open the door? If not ,try shutting it and opening again , might be the switch on the door. Mind you , I don't know what sort of swich it is . could be a simple one or a sensor type.

I can hear it each time i open the door. BUT sometimes its a long pump like 20 seconds after that i get no "CHECK TRANSMISSION" message and sometimes its a bit shorter like 10 seconds after that short sound i get the message after a while i hear the pump again and the message disappear/
