@@speedkar99 hi Great video. My situation. I have a 2020 Nissan Altima 51,179 a horrible strong burning smell was coming from inside car at times and outside of vehicle always. I never ever run it hard I keep it under 2.5 rpm’s. I bought car at 41,000 miles. I was curious to see how CVT fluid was doing so I pumped it out and I have the pics and it looks like cocoa cola. A strong burnt smell this was it. No engine indicators ever came up on for bad transmission etc. My concern is what if I didn’t change the fluid? Could the fluid have still lasted or would the fluid have caused serious problems and burned the surroundings of the steel belt??? I knew there is no exact answer or way of knowing. I really wonder how much more time of that burnt fluid especially with that strong pungent burnt smell could or would have damaged inside the CVT and what would the old burnt fluid damage specifically?? I found this!! forums.nicoclub.com/does-your-car-smell-cvt-tranny-smells-like-burning-rubber-t321697.html

9:32-11:51 showing how the diameters change is one of the best and most helpful explanations of the CVT I've seen. Great work!

I had a 2011 outback that started whining. Subaru garage said it was fluid pump failure. I told them to make repair and they said they don’t repair them. They quoted me a factory authorized used one for $2800 plus labor. I found a garage who got one from a junkyard and installed it for $1200. Drove the car for 232,000 miles and its been passed to two other family members.

If you own a Nissan CVT, change the fluid every 30k. I've flushed mine (not drain and fill) every 30k. At 150k the CVT feels exactly like the day I drove it off the lot with 4 miles on the clock.

I expected the belt to be the primary cause of failures, but really It's amazing those belts can handle the amount of torque and number of cycles they do before failing.

Meaning belt isn’t the failure point. From my understanding w 190k mi on CVT and on the clock keep going. From 2011 2.5 Altima. Most failures come from lack of maintenance (every 25k to 35k fluid change), or excess heat(can be addressed with external cooler. Which also extends oil life about 10k more) and I’m driving this car under extreme condition. Just so you know. 120f AZ heat wouldn’t be any good for this tranny but yet it drives like a sewing machine and makes me smile whenever I get to the gas station. Just don’t forget that CVT suffers from extreme heat. And there are ways to make it run right. Before rebuilt is actually needed. Plus these can take some damages compared to automatic transmission where everything is actually gear. And run by hydraulics where kick down can actually cause more harm for the tranny than it should be.

The end explained my main question.... "is this going back together?" :) nice presentation.

Fantastic video! Was diagnosing a grinding sound for a friend and this and the transfer case we're the cause. Told her to drive it to the dealership for a trade because it wasn't worth it.

Congratulations! Here I am, watching videos about a number of older-model vehicles because I’m planning to buy a relatively inexpensive, but hopefully reliable, used car. I was kind of leaning towards a 2007 Nissan Maxima in excellent condition and with very low mileage, but in slightly less than 20 minutes, you’ve completely talked me out of it! Time well spent!

Thank you for disassembling the belt. That made everything click for me in my head. Everyone else on KZread just mentions the belt and skips over how it actually interfaces with the conical surfaces.

WOW not only did you give clear accurate info I can understand you thru the entire video great audio and camera work, you get the instructor or the year award!!! 😀👍👍👏

@@vasiilie3377 Well not here in Puerto Rico, there is a local program dedicated to problems with cars. 4 hours long total air time, first from 12noon to 3pm and then from 5pm to 7 pm. Every day a poor soul calls with a Nissan or Toyota or Korean car with CVT Transmission problems and most of them are out of warranty and still paying for the car. They end up with a not usable car which they are still paying to the bank. As they dont have 7 to 8 thousand dollars that the transmission cost here plus instalation and re programing. This transmission has been out from 2003 or so, almost 20 years and still is junk. There is nothing that can be done. I consider any car with it a disposable car.

Had the same thought. Maybe this isn’t the most reliable but you can see the ingenuity in the design. I’m sure a reliable CVT could be produced if it wasn’t optimized only for low cost. For example the too-small cooler. That seems like a dumb decision made only for cost savings.

Most of the ones I've seen only have a problem with the spool valve stepper motor. $30 part and just requires dropping the pan and valve body which can be done in vehicle, takes maybe half an hour, and doesn't require complete disassembly of the transmission or replacement like other shops told those customers.

Hi I run a merc b180 with a cvt and love it you are quite right I am not bothered about the driving experience just stamp and go after all I use mine as a mobile kennel and a skip. Not the most reliable transmission I have had two of these fail at around 70000miles with the same fault, the plastic spider that retains the solenoid valves to the valve block fails ( it is the wiring loom to the solenoids and the plug to the loom out side the box) it is internally wired in aluminium which fatigues and breaks contact. Fortunately easy to remove and find a specialist to re wire with copper and never fail again Great vid you should be teaching the nissan master techs
