Judgement time lag test
LINE PRESSURE TEST
Line pressure test port
Location of line pressure test port is show in the figure.
Line pressure test procedure
1.
Inspect the amount of engine oil and replenish if necessary.
2.
Drive the car for about 10 minutes to warm it up so that the A/T fluid reaches in range of 50 to 80
°
C (122
to 176
°
F), then inspect the amount of A/T fluid and replenish if necessary.
NOTE:
The automatic fluid temperature rises in range of 50 to 80
°
C (122 to 176
°
F) during 10 minutes of
driving.
3.
Switch of A/C and light etc. are off.
4.
After warming up A/T, remove the oil pressure detection plug and install the oil pressure gauge [SST:
(J34301-C)] and adapter [SST: (J45542)].
CAUTION:
Make sure to check no oil leak after installing oil pressure gage.
5.
Securely engage the parking brake so that the tires do not turn.
Time lag:
“N” to “D” position:
Less than 0.7 sec.
“N” to “R” position:
Less than 1.2 sec.
Result of time lag test
Possible cause
Longer than standards “N” to “D” position
●
Line pressure is low (pressure control solenoid valve A malfunction, primary regulator
valve malfunction)
●
Forward clutch (slipping)
●
One-way clutch No. 2
●
Oil leak for “D” range circuit
Longer than standards “N” to “R” position
●
Line pressure is low
●
Direct clutch (slipping)
●
1st and reverse brake (slipping)
●
Oil leak for “R” range circuit
●
Oil pump
●
Oil strainer (clogging)
