NO.18 EXCESSIVE SHIFT SHOCK IS GIVEN WHEN UPSHIFTING AND DOWNSHIFTING [SJ6A-EL]


18	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)
