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 normally-high 35R pressure control solenoid 2 is commanded OFF and the following changes would occur in the hydraulic system.
Manual Valve
The manual valve is moved to the Neutral position and blocks line pressure from entering the reverse fluid circuit. Reverse fluid, from the 3-5-reverse clutch regulator valve and the clutch select valve, is opened to an exhaust passage at the manual valve.
35R Pressure Control Solenoid 2
The 35R PC solenoid 2 is commanded OFF allowing PCS 35 reverse clutch fluid from the 3-5-reverse clutch regulator valve to exhaust.
3-5-Reverse Clutch Regulator Valve
PCS 35 reverse clutch fluid exhausts, allowing 3-5-reverse clutch regulator valve spring force to move the 3-5-reverse clutch regulator valve to the released position. This allows 35 reverse clutch fluid pressure to exhaust into the compensator feed circuit in order to assist the 3-5-reverse clutch piston spring to quickly release the 3-5-reverse clutch.
3-5-Reverse Clutch
3-5-reverse clutch spring force, assisted by compensator feed pressure, moves the 3-5-reverse clutch piston to release the 3-5-reverse clutch plates and force 35 reverse clutch fluid to exhaust from the 3-5-reverse and 4-5-6 clutch housing assembly. The exhausting 35 reverse clutch fluid pressure is routed to the 3-5-reverse clutch regulator valve where it enters the 35 reverse clutch feed/compensator feed circuit.
Clutch Select Valve
When reverse fluid exhausts from the default override shuttle valve, shift solenoid fluid continues to hold the clutch select valve against clutch select valve spring force allowing 35 reverse clutch feed fluid to exhaust into the reverse circuit.
