Changing My Cvt 8spd To A Manual 6 Spd-not By My Own Request!

Alright, well where to begin? I have decided to open a new thread in hopes that people in my position can get advice and we can help each other out, as well as get some advice and recommendations from all you experts out there!

Here is the situation: 2003 V35 CVT 8-spd=broken, parts are unable to be made, located or found, but you can buy a new one from nissan for about 21-28k, depending who you speak to. This is however obsurd seeing as the car is only worth about that amount in the first place!

The only solutions I can come up with after it sitting in different mechanic shops for over 6 months is to:

A.) Buy the New tranny for 21K

B.) Contact a guy in NZ, who claims that he can fix it and rebuild it because he has the parts from JATCO and wants 10K+shipping, but who is going to electronically transfer 10k to a stranger along with your broken tranny?

C.) Convert the Tranny to a 6spd Manual which is in the coupe V35 skyline? (This is all pending that a mechanic will do it and I have a few electrical wizards looking at all the wiring and the conversion, but nothing definite yet)?

From these choice, I don't think I really have another choice besides C. Any ideas?

Does anyone actually know the part number of this transmission which goes into the V35 coupe the 6spd manual and have any pics or the wiring layout?

If you do go with option B might worth a small investment to fly to NZ, checkout the guy's workshop and do some homework on local forums or people who have serviced their transmission in that person's workshop. If the guy's legit, it may save you $10k, as going for option C might cost a bit less than $10k I imagine (with parts and labour) and your steering wheel +/- shift paddle may not work anymore... plus finding a mechanic might be a challenge as these car is relatively new not many will know them as well as the old R32/R33/R34 range.

I had an R33 gtst auto to manual conversion - 4 yrs ago cost $5k parts and labour. for a car this new, go figure. estimated maybe $8k-9k but you do end up with a real manual. so both B & C is worth considering, but I not A in my opinion.

I feel for you man, and I hope that no one has to go throught that.

Out of interest:-

1) How many km's has your car got on it?

2) How does it "break", i.e what stops working?

3) What mods, if any?

3) What's your driving style in general? Anything excessive/track/donuts/dumping/granny driving?

If it were me, I'd put the car on a boat to Japan and go over and sort it out over there.

I agree that flying to NZ may save me 10k, but it might also cost me 10K in fixing it. If I could change it to a manual I would save a lot more considering (removal and instalation of the new tranny, flying there and back, shipping of the tranny to and from and my time off work) these costs may add up quite quickly to at least 4k). The thing that gets me about the Guy in NZ is, how did he get the parts? He sounds a bit too confident and I really don't think he can do it, but it is going to cost me at least 4k to find out.

What's the deal with having the car re-exported for repairs, and re-imported again - do we have to pay stamp duty again on 2nd entry?

Just curious on how this procedure work...?

Really good point and may be worth looking into.

If it's just the tranny broken, could you not ship that without the whole car?

Oh, and good luck with it buddy, i would be devestated. Unfortunately it's looking like the CVT is the model to stay away from.

Wasn't there someone else on this board who had a massive issue with the CVT?

With the guy in NZ kleenbeats on the forum has spoken to him and I wont post the comments made about what he was offering and how much he charges, last quote for a new one was just over a million yen FOB and Nissan local wanted $24,000 and was for a dealer.

I will get a current confirmed price for a new one Ex Japan and post it, the oil for the transmission does "not" have a generic choice like all other transmissions which can cause issues, oil is $1,500 local and $600 Ex Japan which has to go sea freight.

and keeping it auto would mean you won't need a manual pedal box and probably can use existing CVT 8's pedal box (accel & brake - no clutch pedal needed), and is the handbrake on CVT 8 is the same as in 5sp auto - which is actually a foot pedal next to the brake pedal?

in manual the handbrake is a real hand brake lever next to the gear shift lever, so again you'll be up to more parts to replace for going to manual conversion.

from my experience with them - you would need the auto controller if you were to toss a 'proper' auto in it. so that to me would be a harness swap. also the ECU is different in them. 350GT auto one is different physically to the CVT.

driftt has the best idea so far.

Still haven't ascertained what exactly breaks or the conditions leading up to the failure. Anyone know? This is with a view to helping us build some preventative measures at the very least.

As I understand it the 350GTs CVT is a unique design, not at all like the one in the Maxima or Presage or other VQ35DE Nissans (this is why I went for a 300GT with the 5 speed)

An entire car can be had from $12-13k NZD (which is a fair bit weaker than the Aussie at the moment), even if you had to buy the whole car and have the transmission removed and shipped it might be an option. You could sell the rest on to a wrecker or for maximum money have someone part the car out for you (I know I'd pay good money for the part-leather seats and the rest has got to be worth something). Obviously the problem here is its a logistical nightmare you don't know how much life the new box has in it.

Edit: The CVT guy in NZ may have access to a few wrecked/parted out cars which could explain things. Best to tread warily though.

      Another little story of weird shit happening

      By MBS206 · Posted

      Ha ha, yeah, I've had one following me around in my parts boxes since about 2007 I believe. Just a little iddy bit hole drilled in the one I have to let it vent out once pressure was removed from the engine side. Still no idea what I'd put it on, ha ha.

      Anybody affected by the M1 minefield this morning?

      By MBS206 · Posted

      Just read this... Just a little bit of a wild one! Do you think the driver was testing out a new feature/device for how to lose the cops in a high speed chase?   I also suspect, if the box has a road sweeper that does magnetic metal pick up, he does a LOT of work in the machining industry. Which is what most of that looked like, machining chips from a mill or lathe. And I bet they're RAZOR sharp! And from an environmental perspective they really do need to actually collect all of those little pieces too. I wonder how many people still cop flat tires over the coming months on that road?   As for insurance company, yeah, it'd be interesting to hear what they say to the owner. But realistically, he's right, that "It's his fault". In the way that, it was his truck that spilled it, so they need to clean it up. However, neither he, nor his insurance company may bear the end cost if they do an investigation and find out it was caused by someone elses negligence (And they know who)...

      Yeah, no matter what bad things people can say about Julian from Autospeed, he at least was capable of thinking and his inclusion of a check/relief valve in the plumbing for the Audi boost controller, that I made a copy of and used for years**, completely eradicated that problem. **It's still lying on my workbench where I put it about, um, 18 years ago and have never found a home for it!

      New fix for low tyre pressure from bmw

      By MBS206 · Posted

      I didn't actually know this! I've seen photos of the H1, mainly outside shots, and they just look "different". I guess there'd be a few little changes like nicer rims, and probably the fact they have nicer looking paint with some depth and shine, which will make any vehicles body look different to the very flat colours of the defence force.   I've watched the guys on GHPC convert their Humvee to LS1, and they've done some really nice front shock upgrade. I'm waiting for the next video on it with the rear end done. I can't remember if they've already done it, or I dreamed it, but I believe they're also supercharging theres. They will be in the future doing proper long travel suspension too.   If you ditch out your big V8, as rubbish as it must be, send it to my place. I'll let the unreliable V8 motor and box be here. I just like V8s... So I'll find something to do with it... Even if that something is just taking up valuable space in the yard. I might have something Skyline I can send back in payment... Or even Ford Barra motors  (From memory you're in Canada yeah?) So you can then play with the legendary Aussie 4L version of an RB...  Except they don't have that distinctive random miss at idle like the RB25 does.

      Or you mean the age old problem of early 2000's manual boost tees, where they never let the pressure out of the line between the boost tee, and the waste gate, so after your first trip on boost, the damn wastegate liked to stay open and be laggy on gear change?
