Hmmm. This puts things in better perspective. Thanks.

 

When I shift from 2nd to 3rd and the car is over 4500rpms it grids badly. Got 21k miles on my '03 touring. Taking it into the shop Friday. Anyone think I'll have to have mine replaced?

 

prob mine is a 03 touring but was grinding at around 3500 new tranny for me

 

This is what is the "classic" sympton.

They will want to check the push rod or something first, change it out, and 75% of the time the need to replace the trans anyways.

This is how I started, but I was fortunate enough to go straight to "new trans". I've personally seen 2-3 go the route I just described.

 

No problem, but of course you shouldn't hear anything that remotely resembles "grinding".

It's just not a quite trans, and it's defintely precise.

 

UPDATE: I took it into the shop. They said they have ordered a new transmission assembly and a new clutch petal. They said that this is common and they've done this with a bunch of Z's and it usually takes care of the problem. I'm not sure if a 'transmission assembly' counts as a whole new transmission but thats what I'm geting.

 

You should call and ask?

I have also heard of them doing this, this should be a rebuilt transmission, which is "just as good" as it comes with the same warranty as getting a new trans.

However "assembly" does not directly equate to a rebuild, so you may want to ask for "clarification".

 

i'm guessing this problem is mainly 03 and early 04 build dates???? mine is like what DAYTONA-ZED.. notchy from 1st to second but no grinds throughout the RPMS.

 

Yes. This describes my transmission exactly. No grinding at all just notchy in the 1st to 2nd shift. After the tranny warms up it goes away to some degree ,but not totally. Mine is a 2004 model purchased in feb of this year.

 

i figure the notchiness is normal for all trannys...on cold starts,, from first to second.

My problem is the noise.....at idle my car sits there and makes a clunk clunk clunk clunk....sound like it has a aftermarket flywheel or something.

it that grounds for a new tranny.

 

had mine replaced at around 15k miles.

 

mine was replaced at 10 k, under warranty.

bg that is probably not your tranny causing that. maybe a camshaft thing or cats, but that isnt normal.

yes the notchiness is normal b/c the tranny assembly is heavy and big for such a small car.

 

haven't really followed this thread lately, but wanted to let everyone know that tranny #3 is going into my car today

Factory tranny gave out at 8K

I'm currently at 30K and replacing tranny #2

 

mcduck, sorry to hear about your tranny problems, and I bet you never drive your Z hard Try pushing the clutch in when you change gears, the new one will last longer. All kidding aside, did Nissan cover your transmission under warranty when you have a super charger on your Z?

 

Dealer refusing to change it. Coz I'm living in the middle east and had my car imported from Canada

 

NEw to the site. O3 Touring tranny replaced at 17k miles...Habberstad Nissan Long Island.

Problem= Excessive gear whine at low RPMS, Rattling with clutch let out like something was gonna drop out the bottom of the car.. Occasional grind.

 

So far my replacement trans. from July 2003 has been fine [2nd - 3rd gear upshift grind]. 21,000 miles total and about 15, 000 on the trans.

Now I'm confident to change out the whale blubber gear oil for the RedLine I've had sitting ready to go out in the garage for over a year.

 

fully covered in warranty. SC did not affect it at all. Though, my normal dealer would not play ball for putting in my aftermarket clutch & flywheel at the same time. Wound up not mattering since I'm still waiting on the clutch tho

New tranny feels great. Definitely a different feel to the clutch than the prior trannies. Clutch lets out much higher and there's more of a snap as the clutch clamps down. You can really feel it grab when you power shift

I honestly thought of just adding the lightweight flywheel and leaving the stock clutch in.

 

Hard for you to ever knock Nissan when they covered your tranny when you have a SC on the engine. Most automakers would of told you to take a hike. Glad to see they are so nice.
