Fixed: 2002 350Gt-8 Cvt Problem

I've had a problem on our 2002 350GT-8 sedan with the CVT box that has meant we couldn't take any long trips. I've spent 7 or 8 months trying to fix it and just about gave up. Someone on here had a similar problem to me but not identical and they replaced one of the speed sensors.

The problem occurred an a warm day but the CVT usually worked perfectly well in cool weather. After driving for about 25 to 30kms the CVT would go into limp mode as some would call it but actually got stuck in 3rd gear. Our car would give a very slight miss now and then before the problem occurred and then the tacho would go to about 4000 and you were history. If you stopped and let it cool down for 15 minutes you were usually right to go again and strangely many times it did not happen again unless it was a very hot day.

Anyhow, to cut a long story short: I decided to try replacing a speed sensor so brought one and while the car was being serviced I asked my mechanic to replace one of the sensors. He replaced the front one and 3 or 4 days later I drove about 30kms and the problem happened again. I went back to the mechanic and got him to put the old sensor back in the front and replace the rear one. That was about a month ago and I've had a few long trips in very warm weather and it works a treat. So at last the problem is fixed.

Some people say the sensors are on the side of the box and that is what i told my mechanic but after the first fitting he told me the sensors are on the front and rear of the box.

I bought my sensor from www.nissanparts.com.au via a contact form on their site but when I try to go there now my anti-virus kicks up a stink. Anyhow, the email I received was from Gary Smith on [email protected]

The part is a Sensor Assy part # 31935-5P002 and it cost me $220 delivered.

hi

just to touch up.. the one in the "front" of the box is a "turbine speed sensor aka input shaft speed sensor" the one in the back is just a " VSS - vehicle speed sensor" they use the exact same sensor. so they are interchangeable..

I was reading this post and it sounds exactly like the issue we are having with our car. It is nice to know that someone else had this issue and has been able to fix the problem. We have done the CVT service because it was needed anyway.

I must thank you for your information and hopefully it will be asw simple a fix for our car :):thanks:

      I used the radium thing, makes the whole parallel assembly a lot more compact compared to any other way of doing it

      Racetronix also sells those ethanol content sensor bypass blocks. Adapter, Flex-Fuel E85 Sensor High-Flow Bypass, In-line No Sensor (ADF-FLEX-NS): Adapters - Flex Fuel | Racetronix Ethanol content sensor are originally designed to be on the feed line. These bypass blocks are meant to be ran in the feed line and not return. The continental ethanol content sensors have a 3/8" ID and not 5/16". This is why they are ran on the return line directly in conjunction with a low threshold sampling value VS in the feed with one of these blocks.    Haha we think alike, I used both original feed/return for 8AN feed, and one of the Hicas lines as a 6AN return. I also capped off and left the other Hicas line as a spare.

      Interesting, I haven't read about the issue with oil getting into the speedo in the cluster before. I'll have to take more notice with mine. The speedo on my R32's when I've run factory diff and tyre size have never been accurate as far as I can remember. The non Type-M GTS-t did come with 15" 5 stud wheels and smaller brakes, but that's less than 5% of them.

      Good to hear the condenser you picked up off my brother worked all good. Do you think there could be an issue with your AC compressor itself or the clutch on it then? I don't know a lot about them so I can't really help but keen to hear what it ends up being. Keep the build thread going man, it's nice to look back on over time.

      This is a story of my life things, I learned eventually (thanks to someone calling me out) that my enthusiasm for discussing and sharing ideas that it came across as arrogance and I'm like... WTF?!    One thing I'm pretty sure I justifiably pride myself on is knowing that everyone will have things they can teach you, and you're always going to find out that something you think you know turns out wrong - you just don't know what it is until you get there.   Just the bursting enthusiasm that comes with ADHD when you hit something that gives you dopamine dumps can come across like you think everyone else is wrong or don't matter. But yeah, I'm a software engineer by trade and also do tuning in weekends and 100% have long had a reputation for  quickly making connections when resolving problems or forming solutions that I've sometimes had to take people form a long walk from start to end to explain how I ended up where I did when it's seemed "too simple" when I've stated my initial case, and had the "WTF" type reaction when they've realised how much was actually considered haha.   My reward is that I get all the curly problems thrown at me.
