Park or Neutral - Engine Running (Neutral)

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.

MANUAL VALVE (404)
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 BAND ASSEMBLY (615)
Reverse fluid exhausts from the reverse servo and the band release, shifting the transaxle into Neutral.

REVERSE BOOST VALVE (367A)
Reverse fluid exhausts from the boost valve and line pressure regulation returns to the normal operating range.

FLUID PRESSURE MANUAL VALVE POSITION SWITCH ASSEMBLY (34)
Reverse fluid pressure exhaust from the PSA, thereby signaling the PCM that the transaxle is in Neutral (N) or Park (P). #5 ball check valve: unseats, allowing reverse servo oil to quick exhaust.

TORQUE CONVERTER / COOLER AND LUBE CIRCUITS
Same as Park.
