• Based on the TCC diagram, the TCC control solenoid is turned on and off according to the vehicle speed and throttle opening angle, and the TCC point control is performed.
• If any of the following three conditions are met, TCC is cancelled.

TCC Cancel Conditions

• Brake switch is ON
• Accelerator is fully closed (determined being idling)
• Engine coolant temperature is low

Deceleration Slip Control

• The deceleration slip control operates when the accelerator pedal is fully depressed at the start of the deceleration slip range while the vehicle is being driven.
• The deceleration slip control operates even at lower vehicle speeds by sliding the lockup clutch slightly and suppressing engine speed increase. In addition, fuel economy has been improved due to the improved transmission efficiency.
