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

< ON-VEHICLE REPAIR >[TYPE 1 (4AT: RE4F03B)]
CONTROL SYSTEM
Check for foreign materials in oil pan to help determine causes of
malfunction. If the ATF is very dark, smells burned, or contains for-
eign particles, frictional material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates varnish
build up. Varnish can cause valves, servo, and clutches to stick
and can inhibit pump pressure.
-If frictional material is detected, flush the A/T fluid cooler after
repair of A/T. Refer to TM-172, "
A/T Fluid Cooler Cleaning".
Remove servo release accumulator piston and N-D accumulator
piston by applying compressed air if necessary.
CAUTION:
Hold each piston with lint-free paper.
- Apply compressed air to the oil hole as shown, and remove servo
release accumulator piston from transaxle case.
CAUTION:
Strong flow of air will push the accumulator piston out along
with a splash of ATF. Cover the area with lint-free paper and
blow air little by little to avoid this.
- Apply compressed air to the oil hole as shown, and remove N-D
accumulator piston and return spring from transaxle case.
CAUTION:
Strong flow of air will push the accumulator piston out along
with a splash of ATF. Cover the area with lint-free paper and
blow air little by little to avoid this.
