R Position (Reverse Inhibition Control)

R Position (Reverse Inhibition Control)

Outline
^ The driving force of the input shaft is transmitted to the reverse and high clutch drum, and then to the front sun gear through the reverse clutch, causing the front sun gear to rotate counterclockwise.
^ None of the low and reverse brake are operating, however, so this force is not transmitted to the output gear.





Operation
^ Line pressure applied to the manual valve is transmitted to line pressure, which engages the reverse clutch.
^ Neutral shift solenoid valve is ON, the low and reverse brake does not engage.
^ Line pressure driven to the pressure regulator valve is transmitted to torque converter pressure and sent to the torque converter through the TCC control valve.
