CTV pros and cons
Personally, I am not a fan. I like a standard transmission with direct drive, you can feel that you can control the power better. But that’s the way of the future CVTs–all hybrid cars have to be CVT because these eclectic motors and gasoline motors and the only thing that can connect two of these, is a CVT transmission. So, Hondas and Toyota hybrid cars all have a CVT transmission.

You may feel a delay when you step on the accelerator. That`s because, compared to a regular automatic transmission, there`s a slight pause as the CVT band adjusts. CVTs can be hard to get used to because they just don`t feel the same way a traditional automatic does.
In a typical CVT, when the engine is revved hard, the gearbox goes into an overdrive. So, you`ll notice that the engine starts making the revving sound but the gearbox doesn`t upshift quickly, inducing a slight head-nod. This is also where you`ll notice the `rubber-band` effect of the CVT.
In general, CVTs are no more or less reliable than traditional automatic transmissions. But it may be their application are better suited to smaller cars than larger vehicles.
Like the DSG, a CVT system offers a smooth gear change with an uninterrupted flow of power to the engine. Unlike the DSG, however, a CVT system uses a series of pulleys and belts rather than a fixed number of gears. This means that the DSG won`t always be running at optimal momentum.
Because there is no real shift from one gear to another, this transmission offers a much smoother ride than either an automatic or manual transmission. Because the RPM is always relatively steady, they can also get better gas mileage.

When I was a kid, we used to do it on cars and motorcycles all the time. But those were simple vehicles in those time, they all had a carburetor. So, if you put a straight pipe on, all you had to do is re-jack the carburetor so it ran well and if you didn’t, then you’d get those clunkers that backfired because they weren’t running right. We had to re-jack carburetors. But on the modern car, they all use fuel injectors. The only way to get those to run right is to find a real pro who has a dynamometer, gas analyzer, and knows how to reprogram your computer. So, it gets really expensive to do that right. Realize that, you can do it but it will cost you some serious money to do it correctly.
As your car warms up, the idle gets lower and lower. The lower an engine idles, the more vibration will apparent. When you turn your A/C on, your car idles up to compensate for the extra load placed on the motor.
Cars use a number of methods to dampen vibration. Not only engine mounts, but balanced shafts and wheels as well as suspended weights in select locations. As these items age, they begin to collapse, become compressed, and lose their pliability. This is unfortunately a normal part of an aging vehicle. Figuring out what to replace to fix a random vibration can be infuriatingly difficult. Many times a technician can perform some pry bar tests or power braking tests to find what is not performing as new. But this is something that can be very difficult to isolate.
As for the struggles in third gear, I don’t see a connection between the two. Usually if a vibration is occurring, it will occur at certain speeds or RPM’s. Regardless of what gear the car is in. It is possible that third gear is the speed where the frequency is the strongest. Either way, this is likely going to be a difficult thing to track.
Even so, I recommend have a technician take a quick look at it. I say quick, because this kind of thing can take a lot of time with no results. The amount of time spent should be proportional to how bad you want the vibration gone.
If you decide to get this fixed, I recommend getting a certified mechanic, such as one from YourMechanic, who can diagnose the shaking/vibrating in your seat and help you fix it accordingly.
Good luck!
