There is an additional important fact regarding automatic transmissions, which it would appear has not seen previously mentioned here. This in spite of continual self acclaiming, expletive announcements by Harvey, who audaciously claims utmost superiority in respect of both knowledge and class status.
The SVX transmission was designed to be both couth and smooth, rather than suitable for traffic light drag racing and components are incorporated accordingly. It would appear that the major factors given prominence in threads, have been confined to overall line pressure. There is another issue in this respect, which can be raised with advantage. When a column of high pressure fluid (incompressible), is started or stopped by a valve, in order to control a device which terminates the line, a pressure spike is created. This spike, unless suppressed will cause not intended, extreme and sudden, operation of the controlled device, e.g. clutch or band. Pressure waves, in the form of what is in effect, high frequency water hammer, can also be generated with destructive results, In order to combat these problems, the SVX transmission incorporates pressure accumulators to protect the shift circuits. These operate broadly as has been previously described in regard to line pressure control. Each accumulator is set up to provide appropriate dynamic response and so dampen the associated high pressure spike. A worthy guess is that one of the modifications carried out by “Level 10”, as their best kept secret, is to modify the action of the pressure accumulators by changing the control springs from standard, so as to provide harder shifting. The proper way to test the results, would be to hook up a transducer and oscilloscope to view the pressure waves. Whether “Level 10” would have gone to these ends, is a matter of conjecture.

There is very good reason to understand that all I have said is accurate. Exact information can be found in this thread. http://www.subaru-svx.net/forum/show...306#post442306
