V35 Cvt-8


Recommended Posts

I like the idea of the CVT-8 but have seen on here that some people have had horrid experiences with them. Is there a converse though? Has anyone had extended trouble-free mileage on a CVT-8?

well from what i have read on forum is that as long as you change the oil in the box @ the right times you should be ok, mind you the oil is super expensive for a full trans flush. The other problem is that not many people know how to fix the CVT auto if something goes wrong

I've had mine for 15000kms and haven't had any problems yet. The odometer is still fairly low @ 44000kms though. I don't think the CVT box is as fragile as people on this forum put it out to be, its just that if in the rare case that if something goes wrong, no one knows how to fix it - so even if its a minor problem, it then becomes a major problem.

I still love the paddle shifts and starting to love the way the 'box kinda spools up when you put your foot down. :P

Mine's at 61000km and still going strong, never misses a beat. Very smooth during day to day driving, and paddles for those spirited times!

As per what Tien said, the problems aren't all that people put it out to be. People whose CVT trannies 'breaking' or 'exploding' on this forum have not given us the exact low-down on how theirs broke/the cause, leaving us to conclude that these failures are attributed to excessive abuse. Changing the oil every 100,000km I believe should be enough for a trouble-free life - expensive though.

100,000km ? Is THAT the normal maintenance cycle? Then its like the timing belts - big repair every 5-10 years, Hmmmmm - not so bad.

When do you suppose to change the Tranny oil? Mine only done 35K km atm and 2003. Not sure if ever been changed or not.

Hey guys, I have researched this quite a bit since I have the 350GT-8 myself. The information I have may already be known, but its scattered around so I'll put the most important facts here.

1 - The transmission was made by Jatco Ltd. They make transmissions for a lot of major car companies worldwide. (www.jatco.co.jp/ENGLISH/index.html)

2 - However the rollers within the transmission, (utilising molybdenum for durability) were made by NSK Ltd. (www.nsk.com)

3 - The unique transmission oil was made by Idemitsu Kosan Co. Ltd, they even won awards for it. (www.idemitsu.co.jp/e/lube/index.html)

Now onto the question of maintenance. Below is a graph from the Idemitsu Kosan website which shows the practical performance of the oil over a given distance.

You'll notice that the fluid degradation starts rising at around the 90,000km mark, and from that point forward, rises steadily.

This, in my opinion, would indicate that a complete oil change should occur at no later than 120,000km, to minimise potential damage.

My 350GT-8 is at 130,000km and is only now starting to show signs of deteriorating performance. I will have the new oil in a few days, then I can change it and update all on the difference a change makes.

I went to see a V35 GT-8 on Saturday and loved it but after discussions with the selling dealer - and note this - on that car which was in very fine condition - he would only offer the statutory 3 months warranty wheras all other stock had 12 months extendable to three or five years - I just baulked. So... much as I liked the idea of the CVT-8 the potential for financial disaster was too much to worry about in a car of this price bracket. Anyways.... now I'm working to import a manual 4 door - at least that's a known quantity and repairable here (basically same box as the 350z) for the usual type of dollars.

What were the specs and price on the car in question Larry?

The car itself was lovely - Silver, Leather, Bose, Sunroof, Tint, Rear wiper - lovely car and everything I want. Price was a few grand higher than they are going for generally at dealers but you know how it is - there are 'Dealers' and there are Dealers so because this place has a good reputation that didn't worry me too much. Mileage was high - about double the norm for a 2003. Condition was about a Grade 4 - some minor paint defects. If it was a 5 speed or a manual, I'd most probably have bought it.

might want to think about importing a second time.

just got a car from J-spec and Craig was great with finding exactly what i want (70th anniversary V35 coupe). but due to the crappy doller.. i had to pay almost AUS $ 1000 more on the FOB price.. and when the Car lands then again shipping fees have to be paid on US $ and i am guessing that not going to be a good rate either..

so unless you can not really find anything you like locally, might want to think twice about importing.

another thing i notice bidding on Jap auctions was that although japan is in the middle of a much worse economic crisis than us, the auction prices have not comedown by much .. well i only know about v35 the auction prices , definitely not to out done the Aus $

    • Your stuff look much better than the original stuff I used on my tri-y headers, which didn't survive the swap, that did work OK though, but currently the headers are only ceramic coating, which, while it is meant to be the bees knees, it really only reduces temps by "not alot" and is more for protecting the mild steel pipes The new stuff is meant to maintain an "air gap" which "apparently" helps the insulation LOL In other news I'm taking it into Autotech next week for them to have a look at the RaceTCS, the spot where I want it, and the program "thingie" that is on my lap top computa which you would know as it is basically the same thing as your Racelogic  I'm really keen to get this fitted  
    • OK, a couple of questions arise. Are you suggesting that you want to swap to the S2 ECU so that you can Nistune it? Because....none of the R33 ECUs can be Nistuned. What would an ATESSA controller do to help? You have no ATESSA. Beyond that, the S1 and S2 ECU pinouts are nearly identical, as far as I can remember. A quick look around on SAU yields the following for S1. As I said, almost all of it is identical. I think there might be a few changes around the AFM and the ECCS relay, not much else. There's not functionally anything particularly different between a manual and auto ECU pinout. Can run a manual engine on an auto ECU quite trivially, for example.
    • Hey guys Was recently replacing the water pump and timing belt. Came across one of the washers for the timing gear and balancer were bent. Just wondering how that would of happened
    • Recently destroyed the front driver ABS wheel speed sensor on my ENR34 due to the iron knuckle rusting and seizing the sensor head. The other one on the passenger side has been soaking in penetrant for a few days, but I fully expect the same thing to occur. The wheel speed sensors seem to be specific to the AWD applications, and likewise the more readily available units from ER34s and S/Z chassis are not the same. An OEM unit seems to be available at $200 USD/ea, which is not ideal, but still fine. But if I'm in this boat in the future, those might not be available.   Does anyone know of any wheel speed sensor that uses the same head as the R34 GTR that could be used? Not overly concerned with cable lengths as wiring will be redone to accommodate PMU wiring.
    • Isn't this at least partially due to the way the dyno run was done? I'm used to seeing runs where they start as low as 1500 rpm to see how boost develops over the 2000-3000 rpm range. Seeing the torque curve fall on its face by 6000 RPM similar to this chart gives me some confidence that this run wasn't just entirely make-believe:
