Well Im the proud owner of my first Skyline, a R33 GTS-t 2.5lt.

I haven't had it that long, but Ive come across my first issue, which is 2nd gear grinding, whether its from 1st>2nd or 3rd>2nd there is a considerable amount of grinding before the gear goes in. :(

It started happening yesterday when I was driving it home from work, I tryed changing down from 5th to 4th ato take a bend and 4th gear instantly grinded and wouldnt go in, after than I had trouble getting any gear in, so I slowed it right down and managed to get into 2nd with a little grind, then after that I could change back up the gears fine. But when I got to an intersection I changed down and when I got to 2nd it grinded again. Now it keeps grinding when I try to get into 2nd.

It does get there, but I really dont like driving it when this is happening, it feels like Im damaging it every time I have to go to 2nd. ;)

I took it out today to try double clutching it, and changing to 2nd at lower or higher rpms, but that didnt seem to help no matter what I did, altho by the end of my drive (~10mins) when the car was starting to warm up it seemed to improve slightly- much less crunch, but still bad.

Ive read a few threads here about the issue, so sorry for posting another, but Id like some more direct advice on what to do.

Ive heard of people replacing their spigot and thrust bearings, and some others replacing the gearbox oil, while even another person got thier ECU tuned and that fixed it.

Im just really hoping it wont be anything major, like a gearbox replacement or rebuild, because I really dont have the money or time for something that major right now...

Im getting the ECU re-tuned next week anyway, so I will have to speak to the mechanic about looking at the issue, but any advice or experiences you guys have would be appreciated so I can get a heads up. :D

sounds like it "could "be as simple asthe syncro's ,which help the gears engage smoothly, when shifting..id take it to a good gearbox specialist and get them to give it a look.If they know about skyline boxes it would be good.....

Yeh I phoned my mechanic (who specializes in skylines) and that was the first thing he said it could be...

He'll have a look at it before he retunes the ECU (no point doing that if the syncro's are out)

Any idea of the costs I may be up for to fix that? If it is the issue...

I know the guy who had it before me recently upgraded the clutch and while he was doing that got the main bearings fitted in the gearbox, along with a few other things. So it makes me wonder why this issue has happened so soon.

Na sorry i have no idea on the cost to replace just the syncro's, I wonder why that pulled it down and replaced the b earings ,that sounds a little weird...Id "estimate" at least 800$ to 1500$,,but dont really no............l

Shit ok, not quite the numbers I was hoping for, we'll see what happens.

You said your clutch was recently changed? Maybe it is not fully disengaging and just needs adjusting?

Im hoping its something as simple as that, but if it was the clutch not fully disengaging then I would expect it to effect all gears, not just 2nd.

I have had a little trouble with 1st and reverse at times, but I put that down to my own error ;)

sychro cone 128 each,,,,i am doing mine,,hopefully get it done next week,,,, :)

Thats not too bad I guess + manhours of course.

The clutch is rather heavy, pressing it all the way down the the floor engages it better and there is a bit less grind, but its still pretty bad.

Im hopefully getting mine done next week also, depending on what actually is wrong. :P

Ill post the results here (and amount of excessive money ill probubly have to pay to fix this)

when i drained the oil,i found a broken clip on the sump plug, by the time i pull the box apart,i found the 3rd,4th sychromess assembly has no clips left,,,,weird,,,,,it took me two days to pull it apart(i have to make my own bearing puller,,,i have never seen such a tool before,,,)

    • Thanks for all the replies fellas. Gonna finish putting it back together and see how it handles the set up. If it starts pinging it’ll be parked.
    • Well, I can recommend the partial AV system translation CD I ordered from Car Audio Workshop in NZ. Whilst it didn't address the date issue, it has conveniently translated on-screen menu items into English, and now allows the GPS-received time to be offset in hours rather than minutes, so I can display Eastern Australian time accurately ( and bump it by another hour when daylight savings starts ).
    • Yuh, if it's 45°C outside, my car is driving in it.
    • I'd be curious to hear more. Otherwise, have you driven a modern x-trail? I wonder how it compares. Here in Australia they are/were popular for rentals and fleet vehicles. I have been in some and my impression was they are bad. But, this may have been very different in the 2000s at a good trim level. Twenty years is plenty of time to make the model worse. I do very much agree with the 2 silver cars in the garage approach. But, not driving because it's too hot would not leave a lot of time in the year for many Australians. I don't think you need to worry too much unless the car has actual issues with overheating. 
    • Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.
