2-3 Shift Solenoid (SS) Valve (315)

WARNING: This page is about a different variant/trim than selected.

When energized, it allows line pressure to enter the 2-3 signal fluid passage and sends it to the 4-3 manual downshift valve (360) and 3-2 manual downshift valve (356). However, this event does not have to occur in order to achieve a manual 3-2 downshift.
