Judgement Suspected parts
At idleLine pressure is low in all positions.  Oil pump wear
 Control piston damage
 Pressure regulator valve or plug sticking
 Spring for pressure regulator valve damaged
 Fluid pressure leakage between oil strainer and pressure regulator valve
 Clogged strainer
Line pressure is low in particular posi-
tion. Fluid pressure leakage between manual valve and particular clutch
 For example, line pressure is:
− Low in “R” and “1” positions, but
− Normal in “D”, and “2” positions.
Therefore, fluid leakage exists at or around low and reverse brake circuit.
Refer to TM-14, "
Shift Mechanism".
Line pressure is high.  Accelerator pedal position signal malfunction
 A/T fluid temperature sensor damaged
 Line pressure solenoid valve sticking
 Short circuit of line pressure solenoid valve circuit
 Pressure modifier valve sticking
 Pressure regulator valve or plug sticking
 Open in dropping resistor circuit
At stall
