Circuit Description

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

The shift solenoid #2 is energized and de-energized by the powertrain control module (PCM) in response to varying transaxle shift demands. With the shift solenoid #2 de-energized, line pressure is applied to the 1-2 shift valve. With the line pressure applied, the 1-2 shift operates, and the transaxle shifts from second to third gear. When the PCM energizes the shift solenoid #1, line pressure is relieved, and the 1-2 shift valve does not operate.
