I took my 2005 Grand Voyager 2.8 CRD to my local dealer in the UK as the transmission dropped down gear sharply twice for no reason and then seemed to go into neutral code p1739 was stored they didnít know what it was that was causing it but thought it might lead to a possible intermittent relay fault this cost me £80 Now the transmission has started to go momentarily into neutral and back to drive with all shift display positions lit-up the drive is jerky first/second gear and intermittent Speedo I have checked all cables and connections all seem fine i have booked into dealers again to see if they can find fault this time and how much is it going to cost.
any help with what the fault maybe would be gratefully received.
Thanks for the replies I had to have the vehicle taken to the local dealers as it became un-drivable after my last posting. There was a clicking under steering column/ dash every time it kicked and jerked violently.
It was two days at the dealers and they found the fault/ cause as follows there was no communication with the TCM they followed the diagnosis through to no power to the TCM with the ignition on from the FCM they checked the circuit to find a open circuit and rather than try to pull the wiring out they over laid new wiring for the circuit all seems fine with the car now in fact it seems to drive a whole lot smoother than before it went wrong but it cost me £280 + vat Labour I hope this info can help anyone else that gets this fault.
