For a complete set of models considered in the present Management are used 4-step АТ series F3А20 (F3А21) and F4А20 (F4А22, F4А23, F4А33 and F4А51). All transmissions are equipped by the blocked converter of rotation. The converter provides direct coupling between the engine and car driving wheels. Transmissions can have electronic control, - in this case the onboard processor makes box switching on raising or lowering transfer, being based on the analysis of the information arriving from three electromagnetic blocks, established on the case клапанной assemblages.

In view of complexity of design АТ, absence on free sale of replaceable internal components, and also necessity of use of the special equipment, composers of the present Management do not recommend to owners of cars to carry out transmission major repairs by own forces. In the present Chapter procedures of diagnostics of general refusals АТ, its routine maintenance, the basic adjustments, removal and installation are considered only.

Sometimes, in case of serious breakage to replace transmission more reasonably and easier, than to waste time and means for restoration of the failed assemblage. Without dependence from the chosen way of introduction given up АТ in action, independent performance of its removal and installation expenses (before make sure, that transmission really requires regenerative repair) will help to cut down substantially.

Towage of the car with given up АТ should be made with a speed not above 50 km/h (30 miles/ch) and on distance no more than 80 km (50 miles)!

Design and functioning principle

Generally automatic transmission consists of the converter of rotation, distributing assemblage and differential. Transmission F3А21 represents 3-step АТ with a mechanical control. Series F4А20 differs a 4-step design and has electronic control.

The internal device of transmissions of both series practically equally. The main difference consists in use of raising 4th transfer on assemblages of series F4А20. Transmission consists of the 3-element converter of rotation with operating regulator (series F3А20), муфты converter couplings (series F4А20), one planetary assemblage, one brake tape and three (series F3А20) or four (series F4А20) multidisk муфт couplings.

Planetary assemblage of transfers consists of two planetary numbers. The structure of a distributing box includes a planetary number with frictional elements of management (blocking муфта and a brake). Work of all transmission the electronic block operates. Switching of high-speed modes is made by means of the car established in salon selector growling. The selector by means of a cable is connected with клапанной assemblage, and with its help it is possible to set a range of used transfers. Besides the selector in salon for the task of special modes of functioning of transmission it is provided one or several switches.

For prevention of breakages АТ at a wrong choice of a high-speed range, for example, moving from “D” in “R” on the selector lever the clamp is provided, - "dangerous" switchings can be carried out only at the pressed button of a clamp. Clamp application allows to avoid a situation when on imprudence one of ranges of movement and the car can be included will start to move uncontrolledly. The selector lever can be established in one of six fixed positions: “Р”, “R”, “D”, “N”, “2” and “L”, appointment of each of which is considered more low.

Position “Р”

Gets out at a car parking. In this position, in transmission all elements of management are switched off, and its target shaft is blocked, - car movement is impossible. To translate the selector in position “Р” follows only after a full stop of a vehicle.

Selector transfer in position “Р” during movement can lead to a transmission exit out of operation!


Position “R”

Backing. To translate the selector in a position “R” it is possible only after a full stop of a vehicle.

Inclusion of a reverse gear during car movement can lead to a transmission exit out of operation!

Position “N”

Neutral position. In a box all elements of management that provides absence of rigid kinematic communication between its conducting and conducted shaft are switched off. The mechanism of blocking of a target shaft is thus switched off, i.e. the car can freely move. It is not recommended to switch transmission in position “N” at movement накатом.

At all do not switch off ignition at movement under a bias!

Position “D”

The basic mode of movement. Provides automatic switching with the first on the fourth
