Flex Lockup Clutch Control

The flex lock-up clutch control is used.

This flex lock-up clutch control regulates the solenoid valve DSL as an intermediate mode between the

ON/OFF operation of the lock-up clutch.

The flex lock-up clutch control operates in the 3rd and 4th gears in the D range during acceleration, and in the 3rd and 4th gears in the D range, and in the 3rd gear in the 3 range during deceleration.

• During the acceleration, the partition control of the power transmission between the lock-up clutch and torque converter according to the driving conditions greatly boosts transmission efficiency, and fuel-economy has been improved.

• During the deceleration, lock-up clutch is made to operate. Therefore fuel-cut area has been expanded and fuel-economy has been improved.
