C1 Drive Clutch
The C1 clutch connects the front planetary carrier to the rear sun gear of the rear planetary set. The C1 clutch is applied in 1st (typical operation during engine braking), 2nd, 3rd and 4th gears.
C2 Drive Clutch
The C2 clutch connects the intermediate shaft to the rear planetary carrier. The C2 clutch is applied in 4th, 5th and 6th gears.
C3 Drive Clutch
The C3 clutch connects the front planetary carrier to the middle sun gear of the rear planetary set. The C3 clutch is applied in 3rd and 5th gears, and also in REVERSE when the vehicle speed is 7 km/h (4 mph) or less.
B1 Brake Clutch
The B1 brake locks the middle sun gear of the rear planetary gear set. The B1 brake is applied in 2nd and 6th gears.
B2 Brake Band
The B2 brake locks the rear planetary carrier in REVERSE gear when the vehicle speed is 7 km/h (4 mph) or less.
F1 One-Way Clutch
The F1 one-way clutch locks the counterclockwise rotation of the rear planetary carrier during 1st gear operation (during both normal operation and engine braking).
Hydraulic Systems
Valve Body
The valve body supplies transmission fluid by switching the transmission fluid circuit for the hydraulic pressure that is generated by the transmission fluid pump. Based on the hydraulic pressure generated by the transmission fluid pump the Transmission Control Module (TCM) sends control signals to the solenoid valves in accordance with vehicle conditions. When the solenoid valve is activated, the control hydraulic pressure to the clutch and brakes is determined (according to the equilibrium with the obtained hydraulic pressure) and gear shift and lockup are accomplished. In addition, an appropriate amount of transmission fluid is supplied to the torque converter, planetary gears and lubricating parts.
