Pressure check трансмиссионной liquids (А4AF3)



 PERFORMANCE ORDER

    Start up the engine before transmission warming up. Lift the forward party of the car so that driving wheels could rotate freely. Connect a tachometre and arrange so that it was well visible. Connect a special manometre 09452–21500 with an adapter 09452–21002 to each union of check of pressure. For check of return pressure it is necessary to use a manometre with a limit of measurement 3 000 кПа. Measure pressure трансмиссионной liquids at various positions of the lever of the selector and frequency of rotation of a cranked shaft of the engine. If pressure does not correspond to demanded values, check up and repair transmission elements.

Preliminary actions if pressure of oil is abnormal (А4AF3)

Malfunction sign
Plausible reason
Actions
Pressure in the pipeline very low (or high).
Pressure in the pipeline concern standard pressure трансмиссионной liquids 2, 3, 4, 5, 6, 7 and 8, resulted in the table

1. The oil filter is polluted

2. Wrong adjustment of pressure by the regulating valve

3. The regulator distributor is polluted

4. There is a backlash of the case of valves

5. The inappropriate pressure created by the oil pump

1. Visually examine the oil filter and, if necessary, replace it.

2. Check up pressure in the pipeline by criterion 2 (Kickdown):
– If pressure does not correspond demanded, adjust pressure in the pipeline and, if necessary, replace the case of valves

3. Check up functioning of the regulating valve and, if necessary, replace the case of valves

4. Tighten bolts of fastening of the case of valves and an adjusting bolt

5. Check up an axial backlash of a gear wheel of the oil pump and, if necessary, replace the oil pump

Inappropriate reduction of pressure

1. Inappropriate pressure in the pipeline

2. A filter contamination (L-shaped type)

3. Wrong adjustment of reduction of pressure

4. Wrong adjustment of reduction of pressure

5. Jamming редукционного the valve

6. There is a backlash of the case of valves

1. Check up pressure by criterion 2:
– If pressure does not correspond demanded, item 1 see

2. Disassemble the case of valves, check up a condition of the filter and, if necessary, replace it

3. Check up pressure by criterion 1:
If pressure does not correspond demanded, repair or replace the case of valves

4. Check up functioning of the regulating valve and, if necessary, replace the case of valves

5. Tighten bolts of fastening of the case of valves and an adjusting bolt

Inappropriate pressure of a brake kickdown
