    Early CVTs were quite notorious for their reliability issues but newer ones aren't really that bad. Where I live, the first Honda City and Toyota Vios with CVTs have passed their 10-year mark and are still running with no issues. What can really put you off when driving a CVT is how it feels.

    It's amazing you can transmit any power at all with such a small surface area between cone and belt. I know CVTs are usually stuck on low power engines, but I'm surprised they don't just slip the moment you give it full throttle.

      Oil pump boost preasure from 5 bar to 50. Cruising speed between 0-15 kW can be 7 bar. Kickdown will first boost oil preasure than engines throttle. Cvtz50 app and obd2 are like movie for me while driving. Locking torque convert are also depended of throttle, hills, mass, oil temperature.... Interesting machine.
      The Throttle pedal controls only the engine, gearbox reads engines parameters, gyroscope, speed and insertion. Downhill is also interesting, it revs higher to steepest downhill to keep the speed....

      I'm daily driving on a Honda CVT with over 112K miles and zero issues. Fluid changes are important! I do floor it from time to time for fun, and I'm not babying it on the highway passes by any means, but my engine peaks at under 190 HP. I've learned from the tuning community the transmission can handle up to roughly 250 HP, but I don't have the money to verify that. As far as torque tolerance in general goes, though... More modern CVT-based setups often have a single-gear automatic for launching the car from a stop, to reduce the load on the CVT from the sudden massive torque of moving a stopped car. I don't have that on mine, since it's a 2013.
      What shocks me about the metal belt CVTs is that there aren't any visible notches or anything on the cones for the belt to grip, despite the fact that belt slippage could potentially kill the transmission. I've also seen a teardown vid of a Honda CVT from a CR-V. It has some similarities and differences. In that video, the belt had slipped. The only visible indication of how it had failed was some scratching on one of the cones, as the other cones had nice, evenly machined surfaces. No debris or anything.

    I remember in the early 1980s someone heard my brother was a brilliant engineer and gave him a bright orange, low mileage Volvo 66 (a rebranded DAF) with a locked transmission to fix, they said if he could sort it out he could have it for free, because absolutely nobody could figure out what the problem was and why it never ran right, not even the main dealers. He puzzled over it for weeks, took things apart and studied them, then rebuilt it and observed it working, trying to resolve various problems. He had me listening to vacuum pipes while he worked the controls until one day a pipe nearly sucked my brains out and he suddenly understood how it worked! After drawing diagrams on paper and retiring to bed he was up early next day and had it working perfectly within a few hours. That car then ran faultlessly for years and he even designed an electro mechanical modification so that he could manipulate the gearing at will by flicking a switch. He said at the time that he had various ideas on how to improve it and that he believed that one day most cars would have cvt transmissions. Shame he lost his way later in life when he decided he was going to be a famous pop star. Don't know what eventually happened to the car and alas these days we don't speak, because as you may have gathered, he's a nutter!

    Last year, I went to the DAF museum in Eindhoven, The Netherlands, where the CVT originates. It was first called “Variomatic” transmission and used in the first DAF cars such as the 600 (about 1959) and in later models like the Daffodil and 33. Many mechanicals of the drivetrain in those cars were external not like CVTs and differentials of today. Really worth a visit. They have old open sectioned CVTs on display.

    Very interesting! In 1959 the Dutch DAF model 55 used 2 belt driven variators to skip the differential. It was the first car to be allowed to be driven by the disabled unable to operate a stick shift. We had a belt driven variator in a drill press and Italian Piaggio was experimenting with their Ciao series of mopeds. Yamaha has great success in their quad bikes with it. Going to steel belts, I had my reservation on how the oil is going to stand up with heavy loads. Personally my choice on auto reliability goes to Toyota Borg Warner units. Looking into the future, Peter Rawlinson has placed his differential right inside the axle of an electric motor. This mimics Subaru's claims of equal torque on each wheel.

    • @coreyp9211

      The benefits are the infinite gear ratios allows for better fuel efficiency, and they are generally smaller and less complicated to manufacture than regular automatic transmissions.

    CVT's are really great for MPG, just with any tranny change fluid more then recommended. Every 30-40k IMO with approved fluid. How about a replaceable belt?...they would never do that...These are non repairable, like the rest of the POS car.

    The same gearbox is in Mitsubishi Mirage (Space Star in EU, 850 kg car), but it has the electric oil pump for Start/Stop to prevent low oil pressure. The same gearbox is in much heavier Nissan Leaf and others. This model has nothing in common with older models. Good video, thank you!

    At mark 15:44 you explained how the “lock up” occurs... so when that happens is when u put it in gear and you feel a bump or thump “engagement” . How would you lessen that hard engagement? And what causes to get worse?
    I have a Rogue and it sometimes does that.

    • @speedkar99
      @speedkar99  Год назад +1

      If the hydraulic fluid is being sent too quickly it will cause a hard shift.
      That could be due to the programming but also if the clutches are worn and just slip and grab.
      Fluid condition and temperature may also be factors in addition to engagement speed.
      Finally check your engine and transmission mounts

    I have a Subaru with a CVT, and it has noticeable “gear shifts.” What’s up with that? It does the normal CVT thing where it keeps the engine within a certain power range, but it also seems to shift gears and the higher trim levels have paddles that let you choose 7 different speeds. An explanation of that would be awesome.

    • @ScubaJonL

      Most modern CVTs have simulated gearshifts for a more traditional feel. It’s basically a software thing if I’m not mistaken.
      Although Toyota’s “Direct Shift CVT” for 2.0 engine in Corolla and Corolla Cross there’s a physical first gear for better acceleration at launch and then it shifts into CVT.
