On 2-3 occasions over the past month I had been getting locked out/getting a horrible grind when up-shifting into 2nd at high RPM. Initially I thought maybe it was just me, but being paranoid the synchros were going I decided to take it into Nissan to have it checked out.
Sure enough the tech drove it and was able to duplicate the problem, "when really getting on it" lol. 2 hours later they called me to let me know that they would be replacing the transmission under warranty.
Transmission arrived today and the Z is scheduled for surgery. Im having them put redline MT-85 in it. I do drive the car pretty hard from time to time, but was surprised that the synchros went bad at 35,000 miles.
Really happy with the guys at Nissan for really looking into the problem and honoring the warranty. Needless to say I'm going to take it a bit easier on my first to second shifts. But hey, what do you expect when you go from a 99' mercury sable to a Z.
