16 — a gear shifting Plate 17 — Clamps 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 Y3/6/y6 — the Electromagnetic valve of blocking the hydrotransformer

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 valves (Y3/6/y1) – (Y3/6/y6) from a plate (16).
4. Remove the electrohydraulic block (Y3/6) 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

Assembly is carried out as it should be, the return to dismantling.
