I also had a 313 '08 in nightblue, 16k and a new box was requested at West's Nissan of King's Lynn. "New box sir? Yes I think you're right, let me find one and we'll book it in for you. Courtesy car you say? OK no problem" So not all Nissan dealers are the same
The above service led me to purchase a 370 from the same dealer, and after much debate I settled for an auto...love it! Has anyone heard of any 370's autos experiencing gearbox problems? This is my only drive, daily commute etc, etc and gets a hard time all the time.
I realise this doesn't help the OP in any way, but don't be put off .
