1. It has not been proven in this case that a clutch has completely failed, so that the first factor to check is line pressure. The transmission could very well be in “get you home/limp” mode, rather than be inoperative and that a clutch could be worn, but not worn-out.
   
   
2. The degree of clutch engagement depends on line pressure and, if the line pressure is inadequate, clutches will slip and if they keep slipping, will ultimately burn out.
   
   
3. The high clutch is subject to the highest level of torque and will be the first to become affected, but will not necessarily fail if a problem is promptly attended to.
   
   
4. The SVX is the most likely user of the transmission to suffer from the effect of insufficient line pressure, due to its relatively high gearing and overall weight.
   
   
5. IMPORTANT: Adequate line pressure depends on the proper closing of a single solenoid valve, which operates constantly at many times per second, whenever the engine is running. Therefore, this valve obviously has a limited life.
   
   
6. This component, solenoid valve “A”, must be treated as the first suspect, in the event that there is inadequate line pressure.
   
   
7. History has shown the huge numbers of SVX’s that have had transmission replacements when the problems have commenced solely due to a lack of line pressure.
   
   
8. The factory service manuals indicate that the first factor to check in respect of trouble, is the line pressure. Good follow-your-nose /common sense and a connection port to simplify this procedure has been provided accordingly.
   
   
9. I think a major factor involving the SVX transmission problems is the labelling of the shift lever as 1, 2, 3, D, rather than 1, 2, D, O/D.

Seems like this as an aspect of marketing hype, rather than good engineering... “Look, you are getting a four speed transmission.”
