I think its about that time for a new CVT. But I would roll with it until it dies completely before I shell out a few grand for a new CVT. I wouldn't trust a junkyard CVT

 

Don't do junkyard go rebuilt and that is odd I just ask my buddy he is a mechanic and that is very odd.

 

Find out what is really the problem before you go spending 25 percent of your vehicles worth on repairs you may or may not need. Are there any codes thrown?

 

 

None taken! I just have a lot of personal experience with junkyard CVT's, and all Nissan CVT's in general. You never really know what you're going to get with a junkyard unit.

I guess it all depends on how long you're planning on keeping the car. It very well could be temperature dependent. If you have any friends at Nissan, see if they can check "CVT Temp count A" and "CVT Temp count B" using the data monitor function of Consult III. If these numbers are greater than 0, then the CVT has definitely overheated at some point during its lifetime and most likely gone into an "overheat protection" mode.

Also look at the "CVTF deterioration date". Nissan says if this number is greater than 210,000, it's time for new fluid. However, I've seen CVTF no higher than 3,000 and the CVT still fails. It can be hit or miss with some CVT's.

I might recommend starting with a fluid change. Perhaps just a drain and fill, to start. Make sure you use genuine NS-2 fluid.

Also keep in mind that a failing CVT doesn't always throw codes. Often times I'd be between a rock and a hard place because I know the customer vehicle isn't driving or shifting properly, yet I would have no codes. If there are no codes, Nissan will not approve a warranty replacement, and then I have to tell the customer, "yes, you need a transmission. Yes, your transmission is still covered under warranty, but no, Nissan won't give me authorization to replace it without any stored codes...have a nice day!"

 

 

How did you end up making out with your CVT? Just curious.

 

Yeah, failing CVT doesn't throw codes is an understatement. I had troubles with my 07, dealership could never duplicate, they just never pushed it over 65 for 10 minutes, that was all it took, then the responsiveness went out and the whine would start, even that first few minutes off the freeway it was a dog slow. Then would perk right up. Never had problems on surface street driving, so it wasn't a big deal most of the time...ran like that for a while, but traded it in before getting it swapped under warrantee. Had other issues with the car, and actually used up the extended warrantee with over $15,000 worth of other repairs, they finally said no more.
