hey, tonight on the way home my 2nd gear started to grind a bit when I put it in...even though I have the clutch all the way in...1st and 5th gear syncro's are going out already...why are our trannys so crappy? Anyone had any expierence with the Primera 6-speed? Iwant one! Anyone have a G20 tranny laying around they wanna sell me for cheap?I bought what I thought to be a Primera tranny..but, it has a diffrent setup than ours do...it doesn't have that little plate on the top so you can get the case off that way...:mad:

hrm, i remember someone trash-talking me when my 2nd gear synchro went out. jee, you must be just as sucky of a driver as i am. :rolleyes:

i'm patiently awaiting my 5th gear to die now. 2nd gear works fine, though! ;)

You guys must drive your cars very hard. I've autocrossed mine for 4 1/2 years, and never had a tranny problem. I'm still on the original clutch too. Its not you two have turbos or anything. I think you are over driving the cars. That's my $.02

My 5th gear was popping out like mad this morning. What a way to start the day. They're bad because Nissan doesn't spend too much money on the trans. However, this site I went to today (can't remember the URL to link it) has a poll of people who had 5th gear popout problems, and it was about 50/50, with a slight bias towards people having the problem as opposed to not. It's a bummer, for sure.

Yes I drive my car hard, but its not my fault that Nissan designed the striking rod seal like they did, its crappy....I put a 200sx gear set in my NX and the first thing I noticed was the 5th gear making a slight grinding noise when I put it in 5th...so that one was messed up, and apparently the striking rod(the thing your shifter rod hooks to)seal is very prone to leaking, my 93 SE-R did...and I put a brand new one in and you can't touch it or something otherwhise it will leak, so I didn't know...and I drove the car to the convention and on the way back 1st gear started grinding whenever I put it in(because almost 2 qts of the MT90 had leaked out :mad:), a lot worse than 5th...like it would clunk and stuff....it sucks...:( Now 2nd gear starts to make the little grinding noise like 5th gear...so in closing..I can't afford to constantly change the gear oil out with MT90 or any other synthetic...so I use castrol 80-90W...just add some like every week...

Guys,

5th gear popout isnt that bad. Not once you get used to it after 6 months without it. You just have to stick to light-to-light racing and nothing over 120 mph please. You can still kick Honda ass in a race to the top of third.
THE HARDEST PART IS NOT DRIVING YOUR OTHER CARS IN 4TH GEAR. I keep driving my wifes Saturn in 4th gear all the time. :rolleyes: :eek: :)

*maybe* I could live w/o 5th, but I have a 200sx gear set in my tranny, and 1st, 2nd and 5th ger syncros are being whores...they're grinding and shit...and first gear you gotta double clutch if you're moving to get it in gear...or elce it will make a nasty grinding noise...:mad:

im on my 3rd tranny and cant even drive my car how I want to for fear of breaking another one :(

here's a driving lesson 101 when you down shit do you just put the clutch in and pop it in a lower gear? if you do we'll after a while your tranny's gonna go. when you down shit rev it into gear example if i'm in 5th and i'm at 3000 rpm and i see this civic behind me and he's pulling up fast and i wanna have a scruffle with him i'll press the clutch rev the car to about 6000 rpm and pop it 3rd gear the car will feel like i didn't even down shift thats doing it the right way i see it amillion time on the street 1 out of 20 people down shift correctly.

I agree mith smoothdaddy here :D ! I have had the 5th gear popout for like 4 years now. Who the hell needs 5th! ANd, it has NOTHING to do with how hard you drive your car, some people had it after 5K others after 150K. its a nissan design flaw. We have to deal with a shitty tranny, but the bonus is one hell of a fine engine!!

no please people don't blame nissan for this if you can't drive or don't do routine oil changes etc. your cars not gonna last at all last friday i saw this guy in a red spec v and his clutch was burnt now is this a design flaw of nissan no the idiot can't drive i drove with this guy before when i seen him at gandy the retard burnt his clutch cause he can't drive. i have a 1992 nx2000 and the gear box is perfect the clutch feels like new and it's still the factory clutch and gear box. i didn't even have the car most those years it had one owner he said he pushed it alot and thats way it has a lose of compression i asked him if he put a new clutch in it or transmission he said no. i was amazed and asked him why does the gear box feel so knew. he smiled and said he knows how to drive.

NX man knows whats goin on....When you downshift you always rev the engine first, then drop the gear. If you just downshift your eventually gonna tear up your tranny and clutch....Rev then downshift...it's like butta.

Sometimes shit just happens, especially if you beat the shit out of it, it's going to break. Expect to break your car if you drive it hard, that's just common knowledge. Does this mean that you don't know how to drive? NO. Does this mean that Nissan builds a crappy trans? NO. If you were a 40 year old woman who drove her car to work and back (never beating on the car, and knowing how to drive a manual trans), would she have the same problems, could be. I expect to break my car, it will, because I don't baby it. Driving a car hard, but right, with full knowledge of what you are doing, you will still break it. And if you've had a clutch last 100K miles you were NOT driving it hard alot of those miles. They're a wear item like brakes or a clutch. Their wear is dependent on USE, not how well they're built or designed. Rev matching a downshift will accelerate the wear on your clutch, plain and simple.

chris,i think you may be mistaken, how does a rev matched downshift accelerate clutch wear?:confused: I was under the impression that it was the total opposite, an accurate rev match will greatly decrease stress/wear on the clutch, but unless you double clutch, the synchros are still matching speed of the gear to engine speed and that a well executed double clutch was the only way to minimize stress/wear on both the clutch AND transmission. of course, I'm only 17, so I may have gotten my lines crossed somewhere along the way;)

Okay, I agree with you about the trannys being a wear item...but aren't they syncros supposed to take some abuse? And what about the piolet bearing design(or the lack there of)? Thats why the 3rd gear always breaks on our trannys...the piolet bearing isnt there to keep the imput shaft from deflecting...but, yes what you are saying is true...everything is dependent on how you treat it...and how you maintain it...

Who was trash-talking Ryan?:confused:

I've always thought that when you drop a clutch on a downshift there's hardly any slip in the clutch, but alot of abuse transferred to the trans, in the form of shock loading the gears. But when you're rev matching you're basically slipping the clutch, so the trans isn't asked to accelerate super fast to match the rev's of the engine, so the clutch takes the load in the form of slippage.

By the way, if you want to properly rev match a shift, you need to rev the engine with the clutch out.

To do this type of shifting, say from 5th gear to 3rd gear, for example, you would do as following:
1. push in the clutch and shift from 5th gear into neutral
2. release the clutch in neutral and rev the engine
3. push the clutch in and shift into 3rd
4. release the clutch and drive

The point of rev matching is to match the speed of the layshaft to the speed of the engine by reving. Only, the layshaft does not spin with the clutch pedal pushed in, even if you rev. This is why your reving needs to be done with the clutch pedal out to match the engine speed, then shift. If you are trying to rev match with the clutch in you are essentially doing nothing but taking longer to shift. It's kind of hard to explain. Let me know if I need to explain this better.:D
