ETRS System Operation: Reverse
WARNING: This page is about a different variant/trim than selected.
- Solenoids D, E, G and PISA are on. The PISA is held on to prevent an unintentional parking pawl engagement if hydraulic pressure at the park servo is lost. Solenoid G shuttles the mode enable valve to provide line pressure to transmission range control valves.
- Solenoid D shuttles the transmission range control valve 2, allowing line pressure to enter the reverse hydraulic circuit feeding the clutch selector valve. The clutch selector valve directs the reverse fluid to the SOWC Servo which holds the SOWC during reverse. Solenoid E directs line pressure to the 57R Clutch.
