#50 GT skyline Sedan

Recommended Posts

I have a 350 GT Nissan skyline 2003 import it is running is safe mode, I have had it to one mechanic and his computer told me it was a stepper motor fault can't find one anywhere. took it to a transmission place he had it for a week and gave up stating it stuck in third, it's a lovely car and i would love to put it back on the road but can't get it to drive any ideas

@Col Shaw Is the car an Automatic or a manual?
And if you can provide the exact fault code, that would be a great help.

Also @GTSBoy just saw your signature... lol

What do you mean "can't find one anywhere"?

Can't find the stepper motor for the CVT transmission or the transmission tried international with no luck

Are you sure that the stepper motor in question is part of the CVT? There are at least 2 other options. Idle control and throttle or traction control.

It could be the tranny's stepper, but if it is, it will be inside it. So....you won't find it without some spanners.

Replacement of the stepper motor in the CVT  will cost a few bucks. Probably only a Nissan dealer will have the scanner that will pinpoint the problem so pay the money for a scan. Then try to find a better auto transmission repair shop for a quote on the repair.

My local shop could do it but its in Auckland NZ.

Here's a motor if you want to have a go yourself( look around on ebay ...some of the ads have the gearbox no so see if you can find the number of your transmission. Obviously they all come freight free from China or you could order through Nissan for much more money (or get a second hand tranny - but a second hand CVT???!!!) :

or you should be able to order it though Nissan for megabucks.

Had it on to computers now only one could connect and it said the stepper motor. I don't know what else to to do the Transmission place in Underwood is I'm told one of the best and he gave up I just thought someone must have had the same thing happen to them so I turned to this forum.  I have had the stepper motor out it's easy in this car but it's back in there so I could move the car.

Fair enough .

Have you had a read of this?

https://gearsmagazine.com/magazine/stop-wasting-money-on-jatco-cvt-stepper-motors/

I assume since you have had the stepper motor out you have changed the (special) cvt fluid and filter.

If you have the energy you could follow this article. test the stepper motor and clean the valve body.

Have you got a price from Nissan for the stepper motor should it be required?

I did speak to Nissan at Northlakes but they didn't have any answers for me they said they had no information on this car it's an import so I started looking around for my self I keep getting told to give up and scrap it but I'd like to see it on road.
