Supported gearboxes as shown don't list the Comfortmatic type in my Motorhome. In the scan I get 2 types of selespeed. Does this mean the gearbox module is the same ? I only ask because I'm not picking up the gearbox module in the connect function. This is finding Airbag, body etc but lists a sensor problem for the gearbox. The engine not starting is my problem so don't want to be barking up wrong tree looking for a fault that is only showing through incorrect diagnosis. Thanks, see attached
