I love this whole engine and gearbox being life long mating partners thing, do you think they put them all out in a paddock and just wait to see which gearbox shoves it's shaft in the back of which motor??? Serioulsy they all have the same ratios etc, and if there is that much variation in the build process that they need to to be mated up there is a problem...

I was thinking exactly the same as you when i started reading this thread, but i wasn't sure on exactly what nissan does to each gear box and engine to match it up perfectly???? And if they do seem to match them perfect, they seem to be doing a pretty crappy job at it

don't think the price of the car really has much, if any connection, with it's reliability... hello ferrari reputation?

case in point, currrent gen M5... guarantee you has had MANY more gearbox failures over the same period as the GTR (ie, first 2-3 years of product life) and this car is what... $180-200K? notorious for gearbox problems... not to mention the $1k sparkplugs :rant:

Not to mention the mercedes range of SL's or anything made by maserati. My dad has a maserati grandsport. 25,000km- Traction control, engine cooling fans, electric windows, transmission all rubbish. Even the Italian leather interior is looking tired with door seals falling off etc etc.

GTR has a never before seen level of sofistication (aka, complexity) of its drive train transmission unit in a car that costs half as much as these italian supercars. Difference is the italians will never fix it and nissan will try to work out the bugs for the next generation.

I also don't think the built quality (seats doorseals etc) Would be of a poor quality like the ones ive experienced in the maserati given my r33 still doesn't have any such issues.

R35 definately much better value than any italian or european competition imo and if nissan can keep making cars like the GTR it will only be a matter of time before their held in the same regard as a brand.

Shit you think with all the R & D that supposedly went into this car, that this would have been picked up at some point during the development phase or in testing!

If I'm not mistaken, the GT-R's gearbox was designed mostly in Australia, by a small Sydney based design house that is a subsidiary of Borg Warner. They were the ones who designed and patented the Dualtronic technology that BW now owns. They were also responsible for programming the Veyron's gearbox for Ricardo.

The GR6 is built in Japan by a subsidiary of Nissan and apparently there was some degree of co-operation during the design. The 'new' Nissan corporation has adopted this distributed engineering model for most of it's new cars. It's purely a cost based decision. Manufacturers have had to change the way they do everything to survive in this market.

and what does this have to do with the quote you replied to???? That a Sydney company is to blame for the GTR's ever increasing gremlins in its transmission....?

The only shit mercs are the A, B and C class mercs, although they are making them better now, never had any probs with the Real mercs, saloons and sports ones, but their was a dodgey batch of engine cooling fans making their way through european cars about 5 years ago which effected everything from merc/bmw/audi/maserati/alfa ect...

The massa traction controll would have been fixed by resetting the ECU, transmissions arn't the best but they dont tend to break, they are just annoying and stiff and would benefit from being ratio'd for takeoff instead of topspeed which they are set up for....if you have the flappy paddles how good did you expect it to be, it was one of the first flappy paddles that ferrari ever brought out into its road cars...

hadn't had any faults with mine wich is the model before your dads (basically same car) and ive had no probs thus far (touch wood) and the things been thrashed since i got it. lol electric windows, they are the first thing to break in any car, my door seals are still as new, my leather seats were looking worn aswell but your surposed to condition them according to how often and where it is kept in storage, usually every 3 months because leather is dead skin, once it dries it cannot heal itself.

Tell your dad to go here www.maseratiforum.co.uk it'll save him from being ripped off by the maserati service centre talking crap and inventing problems with the car.

Seriously though its made by ferrari, how good did you expect the workmanship to be? I'm not expecting miracles from mine but thus far ive had no probs... *touch wood*

It's called providing context.

Yes, it may be the case that that company is responsible. The majority of the GT-R's transmission woes stem from under-engineering not poor build quality. Ask the gents over at Willall about their experiences with the unit.

That doesn't mean that the company doesn't know what it's doing. It's entirely plausible that they were working under a tight budget or time frame (which is likely given the price target for the GT-R) or that they had communication issues with Aichi.

Remember these are the same folks that designed the MDCT unit for BMW and programmed the Veyrons gearbox. Both are projects which have turned out quite well.

In relation to Mercs, on another motoring blog someone mentioned to me from personal experience that the lifters for the SL roofs are a problem. From what I was told apparently a common fragile point over time and replacement cost in the region of $10-12K with very limited availibility of the part, could be wrong, but that's what I was told. I have heard of various problems on E and S Class as well. A KEYLESS go problem on an E-Class (a friend of my dad) was an $8,000 fix. The days of yore are long gone when Mercs were indestructable, but from all accounts they are addressing quality woes seen over the last 10 years.

New S and CL Class look and feel just outstanding if their quality/reliability is a match for their presentation then that would be something. Myself personally I'm keen on a Lexus LS or GS. Not saying any car is perfect, but for the average wage earner wanting prestige motoring a much safer bet than an older BM or Merc. I love the BM's and Mercs, don't get me wrong but I reckon they'd be big money pits associated with many sleepless nights...

I am happy to announce that after 4 weeks, my friend's car is back on the road with a brand spanking new transmission succesfully installed! Well done Nissan!

We both went for a nice Australia Day drive on the Old Pacific Hwy from Berowra to Somersby and back.

His GT-R needs to be run in again but it had no trouble keeping up with me in the 60km zone... It is probably one of the best twisty roads in Sydney and we both stuck to the posted speed limits at all times! :)

      Rv37 400r questions

      By sonicii · Posted

      No idea about the remote start part. If the V37 nav is anything like other Nissan JDM vehicles, you can't get the factory Japanese nav working in australia, a card from a different car almost certainly won't work, those cards are usually matched to the serial number of the DCU.  You could be possibly swap out the components from a AuDM Q50 to get it working, but if this is a new model (2021+) 400R, then you will lose the newer features like ACP/AA.  That said, if you have ACP/AA, just use google maps.. I assume a band expander would be required to get the local radio stations, but don't forget the Japanese FM band is narrower than ours, so you still might not be able to receive all Australian stations. I can't see any reason the tyre pressure sensors won't work here, there is the sensor unit inside the rim and the receiver nearby in the wheel well.  I have never had to change the batteries on my 2015 Q50, so I assume they last quite a while.  A straight battery change shouldn't need them to be re-registered as they are the same unit, that should only be required if you replace a sensor with a new one.   Word of warning, if you ever go into the 'secret' diagnostics mode on the main screen, DO NOT EVER do a 'reset' in this menu, it will erase all of your model specific data in the DCU and you will need a trip to a dealer to re-program it all, which would be particularly painful being an import.  This applies to the AuDM Q50 too.

      There is a known issue with the mix door motor on the Q50 which causes these symptoms, not sure if it is common on the Y51 though.

      Rv37 400r questions

      By elir32 · Posted

      Hey guys. I have a 400R on its way to Australia from Japan currently and have a few questions I’m hoping others may be able to help with.   Wondering if anyone here has had any luck getting the Sat nav unit to work in Australia!? Assuming the Stereo is as simple as a band expanded and tv won’t work?  Seeing as they’re based off a Q50 which is Aus delivered is there any way to link that system to the nav? Nav modules and head unit are different part numbers and appear slightly different at the rear with plug ins etc. can I put my xtrail sd card into the rv37 and will that convert the maps or update to Australian? Has anyone got any advice here?     also has anyone fitted the factory remote start and Security system once it’s landed in Australia? I put an enquirey to Nissan Japan in via a third party, and they suggested it needs a Nissan Japan dealers device to setup and couldn’t guarantee if one here could do it or not. They can supply and I can physically fit it but to setup I would need a dealers device. Any information here would be appreciated also. I’ve seen one here with it fitted already prior to leaving Japan at a dealer/inporter, so clearly passes compliance and works when fitted Japan and doesn’t need changing here.      also, does the tyre inflation sensors work here? Does anything change with them when the vehicle arrives? Where are they actually situated? I’ve read they have batteries and they need to changing at times and seems like resetting involves the nav system?    any help here would be appreciated and any other aust specific information to help would be great. Looking forward to see what the current generation skyline is like and eager to see how many of the gadgets can be utilised here.  Thanks in advance

      Do need to take it with a pinch of salt. One of the adapter failures, they clearly had setup issues with the flywheel.  One of the slipping ones I spoke to and it was pretty clear the throwout was riding, rather than fix, just swapped to a new clutch.    These clutches are being put in anything from 5k offroad 4x4 beaters, GR yaris, 500hp commodores to 1200hp barra monsters. Bound to be some issues in some of them when they are not a simple bolt in affair due to the changes in height.    There is a lot going on in this picture and unless I did the job myself no way to tell what really happened.
