1-2, 3-4 Shift Solenoid (SS) Valve (315)
WARNING: This page is about a different variant/trim than selected.
When de-energized, it allows 1-2, 3-4 signal fluid from the 3-4 shift valve (362) to exhaust through the solenoid. However, this event does not have to occur in order to achieve a manual 4-3 downshift.
