Excessive shift shock is given when upshifting and downshifting

DESCRIPTION

• Excessive shift shock is felt when depressing the accelerator pedal at upshifting.

• During cruising, excessive shift shock is felt when depressing accelerator pedal at downshifting.

POSSIBLE CAUSE

• Shift shock may worsen when the fail-safe is operating. The shift shock may worsen if the accelerator pedal position sensor, TP sensor, or turbine sensor malfunctions.

• Clutch slippage, burnt (C1 clutch, C2 clutch, C3 clutch, B1 brake, B2 brake, B3 brake, B4 brake)

• ATF level low

• Line pressure low, high

• Incorrect throttle position signal

• Turbine sensor malfunction

• Shift solenoid A malfunction

• Shift solenoid B malfunction

• Shift solenoid C malfunction

• Shift solenoid D malfunction

• Shift solenoid E malfunction

• Line pressure control solenoid malfunction

• TCC control solenoid malfunction

• Shift solenoid F malfunction

• Shift solenoid G malfunction

• Body GND and sensor GND malfunction

• Control valve body malfunction

• TCM malfunction

• AT internal malfunction

• TR switch malfunction

• Harness and/or connector malfunction

• Insufficient battery voltage

• Loose parts installation (engine or transmission mounts, suspension, propeller shaft)

• Poor hydraulic operation (Malfunction in range change)
