CVT Transmission

Understanding how a CVT works will help avoid operational errors and extend its service life. Let’s look in more detail at the CVT construction, which includes the following elements:

1. Engine and transmission synchronization module – This module activates when starting movement and helps coordinate engine operation with transmission.
2. CVT unit – This is the main component that provides smooth variation of gear ratio depending on the required speed. 
3. Reducer – This element of the CVT construction enables reverse mode, allowing backward movement.
4. ECU (Electronic Control Unit) – The electronic control system monitors the CVT operation and ensures optimal transmission functioning. The ECU receives information from various sensors, such as speed sensors, throttle position, and other parameters to determine the optimal transmission operation mode.
5. Hydraulic pump – This device ensures power transfer from the engine to the CVT and helps control the gear ratio.

Distinguishing a CVT from a classic automatic transmission can be difficult, especially from inside the vehicle. Often, drivers may see a familiar lever or selector with letters “R”, “D” and others, which are characteristic of automatic transmissions with torque converters. However, under the hood, the CVT construction differs from a classic automatic transmission. This must be considered before undertaking CVT repairs.
