2002-2003 6spd trannies?
I was looking through the forum and saw that some of the people with 6spd trannies were having trouble even with low miles (50,000 miles). Is there a problem with the 6spd trannies? I was looking to getting a 2002 and if this is an issue then maybe I should reconsider.

32k and no problems. 3rd seems to be a little more touchy(only gear I've ever grinded) then the others when flying through the gears... but I believe it's pretty common for the lower gears to have "heavier duty" syncros than the higher ones.
So far so good... I've been very satified with the 6 speed in the max.

I had 30100 miles on my 02 when I traded it in yesterday, and for the alst 2 months I had an intermittent grind in 3rd as well...
I thought I wasn't pushing my clutch down all the way, but when I was testing it it did it when it was depressed.
I have beat on her though, I had two track days with a total of 5 runs, and a bunch of street races.

I'm waiting to have my 2nd tranny installed. I've got 43k miles on the car, and the tranny basically locked-up. I had to shove it into gear using both hands just to get it to move. It's been on the dealer's lot for 1.5 weeks now awaiting a new tranny arrival.
It seems like the problems are isolated at this point, but there are 3 members alone in this thread who have had it replaced.
If it's an 02 you are buying, beware that there is a bad clutch disc that originally shipped with the car. If you buy it, make sure you get it to the dealer before the 3 year/36,000 mile period is up. There's a TSB available on my site for download about the Clutch Disc Howling.

I've got about 44k on my 2k2 Max with no probs with the 6spd. The throws are somewhat long, but I don't have engagement problems . . . Tranny fluid has already been replaced 3x: once after clutch howl TSB by dealer, immediately after I installed Amsoil because dealer did not use GL4 (GL5 will kill the synchros in tranny), then again by me about 4 months later because the Amsoil was VERY notchy in cold weather. I've had GL4 75-90 for the last 20k with no probs - almost ready to replace again.

My 2003 has only 24,000 miles, and I've had trouble w/3rd gear from early on. It grinds when I downshift, and even sometimes when I upshift. When I let off the gas to put in the clutch and shift, usually I can just push on the gas again after I let out the clutch, but to keep 3rd from grinding I have to rev the engine to a higher RPM before I try to put it in 3rd.
I guess the RPM depends on where the gear will be when I let the clutch out, if I am driving quickly, I'll have to keep the engine up pretty high when going from one gear to 3rd, but if I'm grandpa'in around, I just need to have the rpm's around 2000-2500..
basically wherever the engine WILL be, is where I have to already have it...
wierd, and I'm suprised more people haven't said anything about the tranny problems...
I'd imagine the people that aren't having any trouble aren't driving it hard, or maybe they always keep the rpm's up while in neutral...I can't explain it.
There used to be a huge thread on this, and everyone and their brother would complain about it...

[I] Cut the crap guys. I've seen many of you same guys thats saying no problem yet, complaning about 3rd gear being rough to get in.Is that not a problem? Some of yall just can't keep it real. Guess that's a new meaning to "maxima obsessed" I call it denial.
22,000 miles on mine and besides the rough 3rd gear feeling, no other problem.Sometimes I even get it in 3rd pretty smooth, I guess when I concentrate on it

Just a couple of additional thoughts on this:
A misaligned clutch disc "could" grab a little even when the clutch pedal is fully depressed - I wonder if this is a possible cause of the problems some people are reporting.
Also, incorrect tranny fluid can make a huge difference, the Amsoil I tried was horrendous in cold weather, I was grabbing gears during engagement when the tranny was cold. Try to replace your current tranny oil with new GL4 75-90 spec oil, or better yet, try to use the new Nissan part number for their GL4 80-90 lube and see if it helps at all.
It is my understanding that synchros are designed to operate best "between" certain input/output ratios. It might be worth experimenting to see at what engine rpms and road speeds the problem exists. It sounds like many people are reporting problems during downshifts to 3rd. It might be that a high rpm shift into 3rd gear was not optimized . . . Does the problem still exist during a low rpm down shift (try to go 45mph in 6th and then downshift to 3rd).
I don't know if it's made any difference at all, but one thing I did since the tranny was new was to place a powerful magnet on one of the lower bolts on the tranny itself. This step effectively magnetized the bolt, and I hope is helping to keep any small metal filaments out of the main moving parts of the tranny. When I change my tranny oil, I first remove the magnet then I drain the fluid to try and make sure that any/all filings drain out at the same time.
Good luck!

Sure, you get smoother acceleration, but I've never had to do it on any other car I've owned to prevent grinding.
I also used to do this in my old Honda . . . If you are let the engine RPM drop too low, then you are bound to get a rough engagement.
This is my 3rd manual transmission equipped Nissan, and my forth manual overall. This is the first car that has had any grinding problems with my driving habits.
Similarly, if you aren't all the way down on the clutch, then you might also have engagement problems.
that is obviously not the problem, because ony 3rd gear is having the problem.

again, not a problem, as it is only 3rd gear, a problem with a misaligned clutch disc "should" grab a little in EVERY gear, not just 3rd.

Try to replace your current tranny oil with new GL4 75-90 spec oil, or better yet, try to use the new Nissan part number for their GL4 80-90 lube and see if it helps at all.
ya, we'll see, I'll try the fluid, because I need a tranny oil change anyway, but if there was a problem with the fluid, why wouldn't it cause the grinding in all gears?
It is my understanding that synchros are designed to operate best "between" certain input/output ratios.
They should be "designed" to operate "between" any ratios that the engine can handle. If I try to put the car in 3rd gear while doing 120mph, I'd expect to have problems, but at 60mph, I should be able to downshift into 3rd on the freeway AT WILL.
It might be worth experimenting to see at what engine rpms and road speeds the problem exists. It sounds like many people are reporting problems during downshifts to 3rd. It might be that a high rpm shift into 3rd gear was not optimized . . . Does the problem still exist during a low rpm down shift (try to go 45mph in 6th and then downshift to 3rd).
Any car that offers a 6 speed is advertising itself as a "sporty" car, therefore it should be able to be shifted into any gear at any RPM that would keep the engine beneath redline. If you have to "grandpa" the car in 3rd gear to keep it from grinding, to...how did you put it? To, "optimize" 3rd gear, then there is a design flaw with the transmission.

if you're worried about chips, are you having grinding troubles as well?
Good luck!

I've never owned anything but a manual (driving MT's for 8+yrs)
and each has been different, and I'm no fool- I'm under warranty- if something
were wrong -I'd go and get mines!
I've had trouble getting into third once in 15months -racing @ the track under extreme acceleration- is that
a problem? NOT QUITE
As far as the notchiness of the gear engament- some tranny's are like that- I've
owned cars with similar tranny's- some with short throws(seems spongier) and some with longer throws(ours)
I dont understand why some of you bought a 6speed after test driving the car
if your *****ing about notchiness of the tranny(its was the same way when you test drove it) And If you wanna keep it in top notch condition do a 15K tranny fluid service as you should-
For those of you who are having "real problems" you should act before your warranty's up- This throws the misconception out the window that 2k2's are
only ones with this problem (as I see many 2k3 owners complaining)
And best luck

this has become an issue for me...3rd is progressivly getting worse. i have made a concious effort to monitor how i am driving when i get a grind in 3rd...quicker upshifts and i get a chatter going in...moderate downshifts...all i get is earrrereaarrrrrrrrr then it goes in. if i double clutch on the downshift it does it less, but it still does it. if i am gettin on it and going for a very quick upshift...i can almost gaurantee you i wont get 3rd gear. i am very aggreviated about this! it is my only gripe that i have any substance with. i have to drop it off on monday to have the dealership take a look at it. my moonroof stopped working now, so add that to my list too!
