On cars with a 2.0 liter engine, in addition to a 6-speed manual gearbox, a continuously variable CVT (Continuously Variable Transmission) RE0F10A variator is installed (Fig. 6.6), which provides the choice of the optimal gearshift mode for any driving style and various road conditions.
In addition, there is a mode with a manual shift mode, in which during the acceleration of the car, the driver independently chooses the moment of shifting to an overdrive. This allows, if desired, to achieve more intense acceleration compared to automatic mode, making an artificial upshift delay, which allows you to bring the engine speed to the maximum torque range. At the same time, the third-generation electronic control system constantly monitors the vehicle speed and engine load, and eliminates driver error by preventing the driver from shifting up at low speed to avoid engine overload, and downshifting at too high a speed, to prevent exceeding the maximum allowable engine speed. When the vehicle speed decreases, the gears automatically switch to lower gears without the participation of the driver.
When the car comes to a complete stop, 1st gear is automatically engaged. Since the variator uses a V-belt transmission with pulleys of variable diameter, shocks are eliminated when starting and switching. The CVT continuously and smoothly changes the gear ratio as the car accelerates or decelerates.
To repair a manual gearbox (especially a variator), a large set of special tools and appropriate training of the performer are required, therefore, this subsection discusses only maintenance, removal and installation of the gearbox, replacement of its seals, and repair of the drive. To repair the gearbox, contact a specialized service.
