17а, 17b — Bolts
Y3/6 — the Electrohydraulic control unit
Y3/6/y1 — the Electromagnetic valve of correction of pressure of adjustment
Y3/6/y2 — the Electromagnetic valve of adjustment of pressure of gear shifting

Y3/6/y3 — the Electromagnetic valve of inclusion of 1-2 and 4-5 transfers
Y3/6/y4 — the Electromagnetic valve of inclusion of 3-4 transfers
Y3/6/y5 — the Electromagnetic valve of inclusion of 2-3 transfers

Dismantling

 PERFORMANCE ORDER

1. Remove covers at the electrohydraulic control unit.
2. Unscrew bolts 17а and 17b and remove clamps 17.
3. By means of flat-nose pliers, take all electromagnetic Y3/6/y1-Y3/6/y6 valves from a plate 16.
4. Remove the electrohydraulic Y3/6 block from a plate 16. For removal of the electrohydraulic Y3/6 block it is necessary to wring out clamps on an edge of rigidity of the sensor of temperature of transmission liquid.


Assembly
