Most of the people doesn’t know what is different between these 2 types of fluids for CVT and ATF transmission. What if they put into the wrong fluid in their transmission system, it will a big mistake.


In order not to put the wrong fluid, we need to understand the 2 types of fluids first. They work differently in characteristic.


Firstly, we need to know what is ATF and CVT transmission system. ATF stand for (Automatic Transmission Fluid). An automatic transmission, also called auto, self -shifting transmission or AT, this system uses the fluid coupling in a place of a friction clutch, and accomplishes gear changes by hydraulically locking and unlocking a system of planetary gears. These systems have a defined set of gear range, often with a parking pawl that locks the output shaft of the transmission to keep the vehicle from rolling either forward or backward.

There are many sets of gear, Auto Transmission fluid is very important in this system, to provide a lot of lubricant cation and reduce as much fiction as possible when the vehicle is running.


CVT stand for (Continuously Variable transmission), also know as single-speed transmission, steeples transmission or pulley transmission. CVT system doesn’t have set of gears to drive the vehicle. The CVT can change seamlessly through a continuous range of the effective gear rations. The flexibility of a CVT allows the input shaft to maintain a constant angular velocity. A belt-driven design was in the CVT system. There are 2 types of belts, a belt or metal chain belt. The only things that’s make the different for CVT fluid is that the fluid has to produce more fiction rather than less fiction. It is because it’d running on pulley system running by belts, it has to be lubricant cation with more fiction to keep the belt from slipping on the pulley system.


So what do you think if you pour the wrong fluids into your transmission system will cause you ?
