We started with a brand new OEM gear box. That is what will go in for the next race... And will then be swapped after 4 1/2 races.
We are able to get warrantied boxes that have been sent in for gear noise or synchro issues..
They usually get sent in...inspected ..new synchros ..and then we get to use them.
One mans garbage is a another's gold!
;)
This was our first issue at all on the gearbox and it happened pretty quick.

i had a thread about how my 6th gear did the same thing. major fial on nissan for not being able to design a synchronizer that works. i hear redline fluid helps but come on my 95 plymouth neon worth 8large new shifts better than my 30,000 sports car?

$30,000 try $45,000 out the door loaded and you're right it's a sports car, my wife's 1996 328i with 160,000 has no issues, mine with 55,000 is going in for it's 3rd tranny replacement,,, ?????

Double clutching will get you around the problem until you can get the car to the dealer. Its a pain in the butt to do but it works.

Double clutching a sports car,, you are kidding right??

That's funny...because the only ones they've sold have been mine and two others...and of those, one is a 7AT, and the other is a 6MT Syncrorev driven by a school teacher in her mid 30s. Anyone ever written a "good" research paper using only 3 sources.....that don't even a agree.....

Print out the forum bring it to them my dealer told me the same thing that they have NEVER seen this problem before,, to bad their trannys are junk cause I really like the car

about 10,000 miles on it. I'm starting to notice with clean shifts, crunching/grinding when
shifting to 5th gear. Anyone experiencing this? Gotten it fixed?

-Auston

56,000 mile on mine. I am on my 3rd transmission, the last one Nissan built special for me, a prototype,,, We will see what happens here, good thing I got the 75,000 mile warranty ,,,5th gear grinding issues happen again they will be getting the car back. Not spending $45,000 for a car I can't drive. I will drive my old Z's.......

My second gear has been doing that since the beginning. I have scratched it about 10 times already. I haven't taken it in because I don't think I can replicate it without shifting hard like Im racing which is usually when it happens.

My fifth gear does this too! Annoying as hell. It seems to only do it if i skip fourth though, like i hammer it in second or third, and get lazy and put it right in fifth

Funny when I talk to the dealer they tell me they have never heard of this issue,, they must be politcians,, deny deny deny,, "I did not have sexual relations with that woman"........

Well, it finally got bad enough where they can order me a new transmission. Currently at 43k miles. We looked at the option to replace the clutch while they're at it...they said parts for just the clutch comes out to $1,600....I was like :wtf: Anyway, at least they're replacing the transmission under warranty.
