Neutral - Engine Running (Hydraulic Circuits): Notes
WARNING: This page is about a different car, the 2020 Buick Regal and 2019 Buick Regal. However, it is still accessible from the selected car via links, so may be relevant.
When the gear selector is moved to the Neutral (N) position, the hydraulic and electrical system operation is identical to Park (P) range. However, if Neutral is selected after the vehicle was operating in Reverse (R), the 5-7 reverse solenoid and clutch select control solenoid is commanded OFF and the 1 reverse & 6-7-8-9 solenoid is commanded ON and the following changes would occur in the hydraulic system.
