The general information
On cars considered in the present Management automatic transmission (АТ) U140E (the front-wheel models delivered on the American market) or U140F (all-wheel drive models) is established. It is more low considered АТ U140F.
Design АТ U140F
The components involved in work АТ
At the moment трогания from place АТ acts in a role of ordinary coupling, and during movement performs work on a gear change.
Basic knots АТ are: the converter of the twisting moment (hydrotransformer), a planetary reducer and the hydraulic or electronic block of management. To transition to other transfer relation in a planetary reducer are applied гидроприводные disk brakes and disk coupling.
The converter of the twisting moment on the functions corresponds to hydraulic coupling. Its problem includes coupling realisation at трогании from a place and a gear change.
The control system of transmission is a component of a control system of the engine and on the basis of the analysis of the data arriving from various information gauges (not necessarily directly related to functioning actually transmissions), chooses optimum from the point of view of profitability, smoothness of switchings and so forth a mode of functioning АТ. At failure detection in memory of the block of management the corresponding code (Specifications to the Head of System of an electric equipment of the engine see) registers.
Components of a control system of transmission
Unique procedure of service АТ which performance should be made on a regular basis, check of level of its working liquid (ATF) which order of performance is stated in the Head of Adjustment and car routine maintenance is. Necessity for regular replacement ATF is absent.
Near to a radiator of system of cooling of the engine cooler ATF is established.
Transmission operating modes are described in the Head Controls and operation receptions.
Thanks to application Д/В of modes «P» / «N» engine start can be carried out only when selector AT lever is in position «Р» or «N», that allows to prevent casual movement of the car at start attempt.
In the present chapter the general procedures of service АТ laying within qualification of the average mechanic-fan are considered only most.
