    Did you change out the correct CVT oil when you bought the car?

    Buying 2nd hand car, should just give all the fluid a complete change. Like what bro. Izso mentioned, change the CVT fluid and give it a try first.

    After I received the car I had change all the Engine oil/cvt oil. I had take this car from Johor to perak after the oil change. Everything is running smoothly. Just when you drive it slow,the gearbox start a little bit sluggish.

    Have not heard of any Additives for CVT box, so far only helps with auto boxes. CVT probably need to check the drive band

    Is it the specified ATF fluid or u dont know what fluid they pour into the GB?
    Using non specified ATF will damages the GB for sure. Its like having a ticking time bomb.
    A friend of mine driving a Stream was using non specified ATF for top up due to on tight budget. The gb behaved normally for 2-3 month before it cannot shift into gear at all. If it does shift, there will be loud metal clanking sound.

    Anyway, i am not saying your gb is kaput. Could be just a simple thing as low fluid level. Most modern car dont have dipstick for its gearbox and require specific method of replacing the fluid which if not followed will result in improper fluid level which then will cause all funny2 behaviour.

    Bro CVT is well known for jerking when in traffic jam. It is normal. My friend just bought a new Civic FC and he also say his car will jerking when in traffic jam.He say he complain to SC and SC say is normal for honda CVT.

    I'm driving Suprima S, also using CVT. Before this have jerking issue when in traffic jam but since still under warranty, i bring to SC and complain for jerking issue. they help me to do clutch adaption on my car TCU. now no jerking already..

    Lets hope its not behaving like Exora bold CVT when climbing super steep incline from standstill with 4 people and some luggage. It doesnt climb at all even when u floor it. It just revs to 1800rpm and then drop back to idle where most will panicked as the car start to roll back.

    After i send to do clutch adaption on my CVT, so far have no issue with jerking, but dont know will last how long lah haha ! Anyway, recently i tried with full load of people and stuff while going up to Genting on CNY, so many car that day and causing traffic jam. My car will not roll back when moving from standstill, I think because of the hill hold assist function and surprisingly the car is smooth..

    For this Jazz I had made a service by using Valvoline fully sync cvt/ 5-30w fully sync.

    When going around 50 above is smooth. Just some jerking when going in low speed. I am still new in cvt so I am not sure about is normal jerking in low speed.

    Yeah CVT is not like normal Auto transmission. When you are moving from standstill. Please allow your car to roll few second before you press the pedal to prevent sudden jerking.

    for ATF, its not about the brand but the type of ATF ( Dexron I,II,III, Renaultmatic D3). there are plenty of them and using the wrong type will almost guarantee gb failure.

    Anyway driving a cvt is not the same as driving normal torque converte autobox. I havent exp cvt with torque converter so camt comment on that. If u can test another similar jazz then u can see if its a normal situation.

    That's why. All my experience in CVT cars (Lancer GT, City, Sylphy) are very smooth.

    Honda CVT oils if not mistaken is HCF-2 or something like that - not all CVT oils are the same. Nissans one is NS2/NS3 which is not compatible with the Honda CVT oil apparently. So better double check to see if your Valvoline is Honda compatible. I can't remember the type of CVT oil Honda uses and I'm too lazy to google.

    Last time when I had a Sylphy, I tried going with the Pennzoil universal gear oil that was supposedly NS2 compatible (Nissan CVT). After using it for a short while I found the gb struggling a lot and felt heavier than normal. Turns out the "fully syn" universal gear oil didn't really work that well in my old Sylphy. End up I dumped the oil and after swapping back to NS2, it worked great again. Expensive lesson to learn.
