5th gear "crunching" with shift

terbo · 04-03-2010, 02:12 PM

Glad to know it's not just my car. Hopefully Nissan will get their crap together and fix these issues. My car does the grind when I skip 5th and shift into 6th, usually at a higher RPM. To avoid it crunching I usually pull it out of 4th/3rd and press it against 6th while I wait for the RPMs to drop and it will slip into 6th by itself easily. Still it's very annoying.

Nissan wouldn't have these issues if they went with a reputable transmission manufacturer, such as Getrag, instead of desiging their own.

In two days I will officially be on my 3rd transmission... first it was a grind from 5th to 6th, now it's from 4th to 5th. The general service manager thinks Nissan will void my powertrain warranty (which sucks already coming from a previous Hyundai owner - 10 years/100,000 versus 3 years/36,000 miles) since no one in the area has had these problems... 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.....

how exactly does one go about grinding a gear... like if they wanted to do it on purpose. i dont really understand how someone grinds the gears in their car.

Leave the clutch unpressed and move the shifter towards a gear.. it will grind like crazy.

Problem is when the synchros go bad, you can't stop it from grinding (unless you wait seconds before completing the shift)..

Damn Nissan gear box, it's so damn clunky is scares the hell out of me even when it's acting normally. Thankfully the clunk differs from a grind.

The G35 coupe gear box is worse than the 370Z's.... No issues for me so far...

Red370 · 05-05-2010, 09:13 PM

i've noticed that mine grinds from 6th to 5th on a downshift at highway speeds every so often, makes me grimace every single time, wonder whats up with it...

How many miles is everyone having these issues? As reported, mine was at 10k

I first noticed it at probably 500 miles and by about 3000 miles it was to the point where I can't skip 5th if I don't want to grind 6th and I have to shift slowly. My car is at 8500 miles now.

Very good question.. I started noticing problems at 8-10k.. didn't take it in until about 19k when I couldn't NOT shift 5th without grinding..

Then I was obviously aware.. had issues at 12k.. replaced.. then 15k.. kept taking it back.. took a couple visits before they would warranty on each occasion.. but ultimately it was evident that it wasn't me doing something wrong.

Now I'm technically out of warranty at 98k.. but I will say I have no issues.. and it's been probably 35k..

It's weird that most don't have issues.. but some do.. almost like it's an on-off switch to whether you'll have problems or not.

I'm hoping I now have a 'good' transmission.. and won't have to worry about it.
