ETRS System Operation: Neutral

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

Solenoids F, G and PISA are on. Solenoid G shuttles the mode enable valve to provide line pressure to transmission range control valves. If shifting from Park to Neutral, solenoids C and D are on for 350 ms or less which shuttles the transmission range control valves, applying the park servo which disengages the parking pawl.
If shifting to neutral from reverse or drive, the PISA is held on and the mode valves are returned to their default positions. Hydraulically, the system is in a Park state at this time. However, because the PISA was held on during the shift from R/D to Neutral, the parking pawl remains disengaged.
