Design of the selector module (without function of the consecutive choice of ranges, - models of early years of release)

67 — the Clamp of position of the lever of the selector
68 — the Mechanical disconnector of switching D-4
69 — the Mechanism of blocking of switchings of R/P
72 — the Indicator of position of the lever

S16/10 — the Sensor of provision of AT

Card of identification of plugs of the 13-contact socket of the electrohydraulic control unit of switchings

1 — the Sensor of 3 turns (Y3/6n3)
2 — Э / the magnetic valve of adjustment of the modulating pressure (Y3/6y1)
3 — the Sensor of 2 turns (Y3/6n2)
4 — the Entrance signal of the sensor of temperature (Y3/6b1) and contact of blocking of a starter (Y3/6s1)
5 -
6 — Supply voltage э / magnetic valves
7 — sensor Supply voltage

8 — Э / the magnetic valve of gear shifting of 2-3 (Y3/6y5)
9 — Э / the magnetic valve of gear shifting of 3-4 (Y3/6y4)
10 — Э / the magnetic valve of adjustment of pressure of switching (Y3/6y2)
11 — Э / the magnetic valve (blocking of the converter of rotation) (Y3/6y6)
12 — the sensor Case
13 — Э / the magnetic valve of gear shifting of 1-2/4-5 (Y3/6y3)

TCM determines the current working parameters of the vehicle and exercises control of consecutive gear shifting, proceeding from simplicity of switching and parameters of the movement.

Activation of electromagnetic valves of switching is carried out at the command of the TCM control unit. The required size of pressure is calculated on the basis of the entering data and necessary adjustment adjustment of the transferred torque.
