hey all...went to eastern creek the other night...got excited and somehow broke 3rd gear and now the box needs fixing.

question is...who have you guys gone to and recommend??

also who wouldnt you recommend.

ive been recommended so far by bel garage to go to diff and gears in smithfield.

let me know..also what will it cost to fix approximately??

its a r34gtt gearbox

thanks in advance..

constructive cricism or nothing...anyways...i thought it was unbreakable.

note to others dont quickshift from 2nd at 8000rpm.

presuming you meant criticism? and i wasn't criticising or poking fun at you man, chillax

Good luck with fixing your gearbox

if it turns out to be 2 expensive to fix the current box, why not get a R34 GTR box, or would that be well out of your budget?

Nice guys to deal with, and definitely knows thier stuff oh and prices are good too.

Cheers,

Johno

rb25 boxes are far from unbreakable

it all depends on what clutch your using

for reference I broke 2 rb25 boxes in 2 track days before going for a straight cut gearset

that was only with 300rwkw

well ive been quoted so far $1500 to fix 3rd gear remove/install...is that about the right price???

also ive got a jim berry custom 6 puck carbotics clutch...its a great clutch..obviously good enough to break the box without any slip!

thanks alot for these businss recommendations.

also just on that gtr gearbox note...what are they worth second hand?

Cant see you spending any less then 3.5k-4k I'm afraid, good boxes - 1500 to fix the box!! dayum, im sure you could fork out another 500 and get a whole new box with less KM's! - someone with more experience in this department please correct me on my numbers etc if needed!

Keep us posted man

On the right track Aron, but if your price included labour aswell then yeah i'd go the new recond box, if it doesn't then i'd go for just fixing 3rd gear. But i fear this problem isn't going to just be solved by a new box or fixing 3rd.

Either way though, its happened once, it can happen again with a rebild or a new box, off memory the car in question is pushing out some serious numbers at the wheels (or is estimated to be quite the animal).... it all comes down to how much you can afford. Ofcorse its safer to over kill things like the clutch and the transmission, but then all your doing is transfering more stress to other parts of the car so something else down the line "could" give way... eg: the axel or something.

If you want it done properly, do everything thats associated with the drive train, make it as much bullet proof as you can. Or if money is a bit of an issue like it is for most of us and your seriously looking at keeping the car for a long time, do it slowly over a period of time, throw in the gtr box, put a crazy clutch in it, replace everything that is getting beaten by the massive amount of stress caused by traction and power, do it slowly, or do it when things start to fail. Replacing the box with a standard gtt or a rebuilt 3rd gear is honestly only a temporary fix, the temporary fix could last one massive thrash, or it could go on for 10 years without a problem, its your gamble and your choice, all comes down to money in the end...

i see where your both coming from, i think it was more due to my neglegence and slamming my gear in like a lunatic, yess the 34gtt is now pushing out double its standard power so i im guessing its double the strain, i am going to try and find a gtr box and if i cant then ill just have to go with 3rd gear rebuild and hope for the best as this 34 has already left a massive dent in my pocket trying to get it this fast.

i genuinely appreciate your feedback and please dont hestitate continuing doing so.

Hey you never know, you might be able to get away with a rebuild of 3rd, probably treat the r34 a little nicer lol, and it should still kick some serious ass, with trannys and drive trains its more the sudden shock that stuffs them up,

I have 2 examples, one is car related and the other isn't:

The mine trains/coal trains ect.... are massively long 6 diesel engines strong pulling 1000's of tonnes of material, did you know most of their trains never actually completely stop mooving? They have figured that because there is such a strain on the linkage parts that connect the caridges together that when they accelerate from a stand still this would weaken the links and cariges would need to be repaired more often, essential drive gears near the engines would sometimes get ripped apart because of the massive load they were carrying, so they worked out that having the trains constantly moving would put less stress on the links ect.... there fore it dint ave as much maintenance...

Another example are drag racers.... if you learn how to take off by using the hand brake you won't get a sudden jolt while the gears and rest of the drive train link up, i know of people on this forum who have stupid amounts of horse power with near standard drive trains (usually just clutch upgrades to stop slippage) launching their cars all night long at eastern creek on wednesday nights, they don;t have any problems when they launch like that.

Actually though of another one thats not really related, "its not speed that kills, its the sudden stop that kills" lol.

Nah but seriously if you are slamming the clutch out uber quickly, the chance of a ripped gear increases allot, practice your shifts and hopefully it will end up saving you money in the long run.... unless you slip off the clutch pedal that can happen and then your up shit creek again. hope that helps

  • 4 years later...
  • 5 months later...

Don't mean to bring up an old thread but I have recently done the same thing - smashed 3rd gear into little pieces lol

Was wondering what OP ended up doing?

I was also looking at just replacing with a brand new box, but am now starting to think an upgraded gearset may be the better option. I think my gear destruction was mostly driver error, smashed after a 'hard' clutch kick at Wakefield.

Same, looking for a good place that can look at a 350z gearbox. 5 gear crunches shifting up from fourth at any rpm above 2K (eg. you can hold the clutch down & shift slowly to let the revs drop under 2k before shifting & it won't crunch.)

It doesn't crunch at all shifting down from 6th to 5th.

Tried changing the oil to a better grade to see if that would help but no difference. It's probably the synchro but need to know if it's something where the whole box would need to be reco'd

    • Thanks for the linkie. Certainly always a great deal of help when people post comparisons like these, but I think for now I'll stay away from any semi slicks. I did go ahead and order the sportcontact 7. My buddy has them on his modified A4 and he keeps saying how good they are. For my intended purposes these will probably work real well. I'll report on them once I had the chance to try them out
    • Talk about noisy. Even when I still had the Tomei under the car I could distinctly hear the tires rolling. And I doubt I ever will need maximum grip like on a track. My GTR will maybe never even see the 600hp mark and I need to get used to the car quite a bit before challenging the limits of its handling. For the next winter storage I think I will get a set of these rubber drive-on thingies that have a tire shaped base. Those supposedly really help prevent flat spots.
    • Well our climate is definitely way less hot overall and the weather can be quite picky at times. I just know that during normal road use or even spirited drives there is no way I'd be able to consistently stay in the operating temperature, and constantly changing the tire pressure would also be a royal pain.
    • Input shaft bearing. They all do it. There is always rollover noise in Nissan boxes - particularly the big box. Don't worry about it unless it gets really growly.
    • For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.
