Hi Bro, it fits 4wd gearboxes code W5M31 and 33, it also fits front wheel drive gearboxes F5M31 and 33. But it does not fit Front wheel drive gearboxes coded F5M21 and 22.
My 350z's gearbox grinds when shifting from 6th to 5th. Any idea what is causing this? I read online that it is due to a faulty synchro. Anybody faced this problem before?
