Automatic transmission (4 A/T)
General description
|
|
For the cars equipped with additional resources of passive safety (safety cushion):
- Service of system of a safety cushion and the interfaced systems has to be carried out only by the authorized dealer of SUZUKI. Non-compliance with precautionary measures can lead to inadvertent operation of system or bring system to a non-working state. In both cases severe injuries are possible.
- Work on maintenance has to begin at least in 90 seconds after the ignition key is transferred to the provision of "LOCK" (BLOCKING) and "minus" the cable is disconnected from the battery. Otherwise the system can work from reserve energy of the module of sensors and diagnostics (KDM).

The automatic transmission represents completely automatic type with three speeds plus the raising transfer (O/D).
The hydrotransformer represents the three-element, single-step and two-phase type equipped electronically with the operated blocking mechanism. The device of gear shifting consists of 3 rows of planetary transfer, three couplings of disk type, four brakes of disk type and three couplings of a free wheeling. Transfer is switched by the choice of one of 6 provisions ("P", "R", "N", "D", "2" and "L") by means of the lever of the choice established on a floor. On the handle of the lever there is a switch of the raising transfer (O/D) which allows to switch up in the mode of the raising transfer (except for 4 L) and to switch down from the mode of the raising transfer. Besides, by means of the switch of provision of a parking \neutral of P/N located on a console box it is possible to choose time of change of transfers from two modes, normal and on the run.

Situation "P", transfer on the neutral, the conducted shaft is recorded, start of the engine
Situation "R", backing
Situation "N", transfer on the neutral, start of the engine
Situation "D", forward automatic gear shifting (the transfer raising the 1st 2 3rd 4th is included)
Situation "D", forward automatic gear shifting (the transfer raising the 1st 2 3rd is switched off)
Situation "2"
(Normal mode), forward automatic gear shifting the 1st 2 3rd
(The mode on the run) Forward automatic gear shifting by 2 3rd and fixing on the 2nd transfer
Situation "L", forward decrease the 1st 2 3rd and fixing at the 1st speed
