Yes both the pocket and screen are interchangable,at least with the genuine Nissan Item. I myself have just imported a new facia,stereo bracket and dash pocket for my new stereo install.
Im assuming they reset the tcu but after talking to the head mechanic the tcu doesnt accuratly monitor how hard the box has been driven. So you may have driven the hell out of your car for the last 40000k and the wear counter will only log that as a casual cruise.
can Nissan over there not do the transmission for you? it took some convincing for the dealer to even get nissan head office to send two bottles of KTF to do the service because of the price.

I had my 2002 V35 cvt-8 gearbox serviced last week at Wairau Nissan on the North Shore. Was a few coins over $1000 for the service. Gearbox never had an issue prior with 135k on the clock so was more about giving it a longer lifespan. The fluid came out slightly dirty and the biggest thing I noticed after the service was it seemed to have more drive off the line.Particully notacable when sitting on a hill in gear I no longer need to have the brake on to hold the car from rolling back.
