then was that u that said the dealer did a f-ked up installation and u had to go back to realign the gates?

edub370

FWIW, I went back and forth with my warranty company on this. They insisted that my 5th-6th gear synchros could be serviced by a transmission shop. But two different Nissan dealers confirmed that they do not work on internal parts on the 370Z MT and that they would replace the entire transmission.

I will likely end up having the dealer do the work because the warranty company is making it too much of a hassle to bother saving them money. I was hoping to buy the transmission myself from Z1 and then pay a competent shop for labor and have them install a new clutch and flywheel at the same time.
