General information

In the cars considered in the present manual the automatic exchange (AT) of U140E (hand over the models of front wheel in the American market) or U140F (traction models in four wheels) are established. Down in U140F one considers.

IN drawing of U140F


C1 — the Union of advancement C2 — the Union of straight transfer C3 — the Union of the transfer that it lowers B1 — the Brake of the 2nd transfer	B2 — the Brake of the 1st transfer and a support B3 — the Brake of the transfer that it lowers F1 - the Unilateral union n ° 1 F2 - the Unilateral union of the transfer that it lowers

The component ones implicated in work of in

In the moment of the departure - of the place of in actions like the ordinary union, and during the movement it executes the work in the dislocation of gear.

IT IN cubes of the wheel principals are: converter of torque (hydrotransformer), planetary reducer and unity of electronic control or hydraulic. The hydrodriving of brakes of disc and union of disc is applied to the transition another relation of transfer in a planetary reducer.

The torque converter in the functions corresponds to the hydraulic union. His task includes the implementation of the union in the departure - of the dislocation of gear and the place.

The system of control of the transmission is a component one of a system of control of the motor and on basis of the analysis of the data that arrive of several information sensors (not necessarily straightly made a list to the functioning in fact of the transmission), the way of the functioning chooses the favorable condition of the point of view of the profitability, the smoothness of switchings and so on of in. In the moment of the detection of failure in the memory of the unity of control the corresponding code registers (to see Specifications to a Chief Sistemy of the electric equipment of the motor).

Component of a system of control of transmission


1 - the Sensor of speed of a wheel of secondary gear 2 - In the valve of SLT that calls 3 - In the commutation valve of SL1 4 - In the commutation valve of DSL 5 - In the commutation valve of SL2 6 - the Sensor of turns of entry of the turbine 7 - Sensor of temperature of ATF	8 - D/V of the ways "P" / "N" 9 - In the commutation valve of S4 10 - bad functioning of To/L (THOUSAND) 11 - n ° 3 been overcome with DLC 12 - D/V of lights of the brake 13 - the Main switch of the way O/D 14 - the Switch of the ways 15 - ECM

The only proceeding of the service of in which the implementation has to be done in a regular base is the check of the level of his liquid of work (ATF) which order of the realization is affirmed in the Chief Nastroyki and the regular maintenance of the car. The necessity of the regular substitution of ATF goes away.

Near to an electric heater of the system of cooling of the ATF of motor the fridge is established.

The operational ways of the transmission are described in the Front Administrations and the methods of the operation.

Thanks to the application of D/V of P / N launch of ways of the motor can execute only when the lever of in the SELECTOR is in the situation "P" or "N" what there allows to prevent the chance movement of the car in the departure attempt.

In the present chapter only the most general proceedings of the service of in the moment of the POSITION inside the qualification of the middle amateur mechanic are considered.
