| Basic valve action |
The basic action of the valves in the hydraulic system can be summarized in a simple line diagram. |
| Regulator & control valves |
The transmission has a number of regulating and control valves which can be readily identified in a hydraulic circuit diagram. |
| Shift & governor valves |
The shift valves are control valves supplied with line pressure which is varied by the governor valve depending on road speed. Low speed equals low pressure, high speed equals high pressure. |
