What is the CVT transmission?

A CVT (Continuously Variable Transmission) is a transmission with continuously varying torque. The CVT type of transmission is distinguished by its ability to accelerate dynamically. Drivers can accelerate faster than with a manual or traditional automatic transmission. The CVT is considered very economical, with no fixed gears, which means there are no jerks during shifting and acceleration. Another advantage is its dynamic performance. When using a CVT, owners must undergo timely maintenance to prevent major CVT malfunctions. CVT transmission repairs can be done at QueensATS service center with warranty.

Features of CVT Construction

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.

Main CVT Malfunctions

There are several main types of CVT malfunctions:

  • Electronic module board problems
  • Failure of dashboard sensors
  • Stepper motor malfunction
  • Wear of automatic locking valves
  • Seizure of electromagnetic pressure level valves
  • Wear of cable wiring or wire coating damage

On average, depending on the manufacturer, the CVT service life can reach 155,000-248,000 miles. However, neglecting the maintenance schedule reduces this lifespan by at least half. To identify the exact CVT malfunction and its causes, a comprehensive diagnostic is performed, which includes the following stages:

  • Test drive of the vehicle to identify signs of CVT malfunction such as humming, vibrations, jerking
  • Computer scanning of the vehicle for error codes
  • CVT defect inspection to find and replace worn components

Repair Process

CVT repair process includes the following types of work:

  • Replacement of all rubber components of the CVT
  • Grinding of bearings or cones if damage is superficial
  • Replacement of worn parts
  • Repair or replacement of the electronic control unit
  • Hydraulic unit maintenance — channel flushing, friction lining replacement, valve cleaning
  • Transmission fluid and oil filter replacement
  • Cooling radiator cleaning

 

CVT owners should not neglect diagnostics of their vehicle, and it’s also recommended to replace worn transmission components and used oil in a timely manner. The continuously variable transmission requires a special type of lubricant, which is expensive to replace at a service center. However, such maintenance is mandatory, otherwise CVT parts will be at increased risk.

Professionals recommend changing the oil every 37,000-50,000 miles, depending on the specific car model. When driving off-road or at high speeds, the lubricant should be changed more frequently – every 12,000-19,000 miles.

Queens ATS specialists restore CVTs of any complexity within 3-5 days. We provide an official quality guarantee regardless of mileage. To schedule diagnostics or call a tow truck, call the phone number or fill out the feedback form on the website.
