N Position

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The PCM controls the shift solenoid valves. The condition of the shift solenoid valves and position of the shift valves is as follows:

Line pressure (1) passes through the manual valve and becomes line pressure (25). Line pressure (25) stops at shift valve D. Line pressure (1) also flows to the modulator valve and becomes modulator pressure (6). Modulator pressure (6) flows to the SS valves, the AT CPC solenoid valves A and B, and the AT CPC solenoid valve C. Under this condition, hydraulic pressure is not applied to the clutches.

When used, "left" or "right" indicates direction on the hydraulic circuit.
