Neutral (Engine Running)

NEUTRAL (ENGINE RUNNING)





When the gear selector lever is moved from the reverse position to the neutral position, the following changes occur to the hydraulic and electrical systems.


Reverse Clutch Releases
Manual Valve: The manual valve is moved to the neutral position and blocks line pressure from entering the reverse fluid circuit. The reverse fluid circuit is opened to an exhaust at the manual valve.
Reverse Clutch: Reverse fluid exhausts from the reverse clutch and the clutch releases, shifting the transaxle into neutral.
Boost Valve: Reverse fluid exhausts from the boost valve and line pressure regulation returns to the normal operating range.
TR switch: Reverse fluid pressure exhausts from the TR switch, thereby signaling the PCM that the transaxle is in neutral (N) or park (P).


Lo and Reverse Band Remains Applied
1-2 Shift Solenoid: As in park and reverse, the solenoid is energized and 1-2 signal fluid pressure acts on the 1-2 shift valve.
1-2 Shift Valve: 1-2 signal fluid pressure keeps the 1-2 shift valve in the downshifted position. Lo/PRN fluid continues to feed the lo band fluid circuit.
Lo and Reverse Servo: Reverse fluid exhausts from the servo. However, lo band fluid pressure continues to act on the inner area of the servo piston to keep the band applied.

Important: In park, reverse and neutral, the shift solenoids are shown in the first gear state. This is the normal operating state when the vehicle is stationary or at low vehicle speeds. However, the PCM will change the shift solenoid states depending on vehicle speed. For example, if neutral range is selected when the vehicle is operating in second gear, the shift solenoids will remain in a second gear state. But with the manual valve in neutral, line pressure is blocked, drive fluid exhausts and the transmission will shift into neutral.
