Hello I wanted to make a post for anyone who gets this issue
Fiat ducato 3.0 euro 5 2009 comformatic gear box switching over to manual while driving
You will get the code check manual transmission the bleep sound
It will keep happening on the journey it’s not a nice experience and does get worse
So after many garages and quotes on gear boxes and so on I went under the van with my ramps and bricks to first check all wiring and connectors. With some moving of wires I heard to beep noise telling me the van went back on the reverse camera back in auto
Moved the wires again back and forth and indeed it kept shifting to manual and back
So next I unplugged every connection and removed the harness to check plugs
I was right the 4 plugs number 1 and 2 then 3 and 3 purple and black I will post images to follow
I found the plug bent so I removed then te terminal and it was snapped
You can just buy from fiat the complete harness £260 or a couple of quid for the housing plug then source the terminal by number which I bought from te connectors just take plenty of pics from areas the connectors go back under for the harness I’m no mechanic and found this easy
I was amazed I fixed what no one could saved £1000s it was awkward tracking down parts and terminals but easy to install back in
I hope this can help someone in the future thanks
