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)
