CONTROL VALVE BODY COMPONENT OUTLINE [SJ6A-EL]

E5U051321100N01

• The control valve body supplys oil by switching the oil circuit for the hydraulic pressure generated by the oil

pump. Based on the control signal from the TCM, the solenoid valves are activated to control the hydraulic
pressure to the clutch and brakes, performing gear shift and TCC. In addition, an appropriate amount of oil is
supplied to the torque converter, planetary gears and lubricating parts.

Shift control

• Detects engine load and vehicle speed, and switches to optimum gear in accordance

with preset shift program.

• In D range, automatically switches between NORMAL, POWER, DOWN-SLOPE, UP-

SLOPE modes according to specific conditions.

Manual mode shift control

• Shifts to selected gear position by manual shifting of the selector lever forward and

back.

• The up/down operation of the steering shift switch is the same as the manual operation

of the selector lever.

TCC control

• According to preset TCC point, performs TCC operation.

Torque reduction control

• Optimally controls engine output torque when shifting.

Shift learning control

• Performs optimal correction for clutch engagement pressure to reduce changes in

engine performance and/or elapsed transmission.

On-board diagnostic system

• Detects and/or memorizes failure of input/output part and transmission condition.
