1996 TOYOTA T100 (RM449U)
Evaluation:
ProblemPossible cause
(a) Stall speed low in D and R positions
Engine output may be insufficient
Stator one−way clutch is operating properly
HINT: If more than 600 rpm below the specified value, the torque
converter could be faulty.
(b) Stall speed high in D position
Line pressure too low
forward clutch slipping
No.2 one−way clutch not operating properly
O/D one−way clutch not operating properly
(c) Stall speed high in R position
Line pressure too low
Direct clutch slipping
1st and reverse brake slipping
O/D one−way clutch not operating properly
(d) Stall speed high in D and R positions
Line pressure too low
Improper fluid level
O/D one−way clutch not operating properly
(b) Measure the time lag.
When the shift lever is shifted while the engine is idling, there will be a certain time lapse or lag before
the shock can be felt. This is used for checking the condition of the O/D direct clutch, forward clutch,
direct clutch, and 1st and reverse brake.
NOTICE:
Do the test at normal operating fluid temperature 50 − 80°C (122 − 176°F)
Be sure to allow 1 minute interval between tests.
Take 3 measurements and take the average value.
(1) Fully apply the parking brake.
(2) Start the engine and check idle speed.
Idle speed (In N position and air conditioner OFF):
3RZ−FE: 700 ± 50 rpm
5VZ−FE: 700 ± 50 rpm
(3) Shift the shift lever from N to D position. Using a stop watch, measure the time from when the
lever is shifted until the shock is felt.
In the same manner, measure the time lag for N → R.
Time lag:
N → D Less than 1.2 seconds
N → R Less than 1.5 seconds
Evaluation (If N → D time or N → R time lag is longer than specified):
ProblemPossible cause
N → D time lag is longer
Line pressure too low
Forward clutch worn
O/D one−way clutch not operating properly
N → R time lag is longer
Line pressure too low
Direct clutch worn
1st and reverse brake worn
O/D one−way clutch not operating properly

7. HYDRAULIC TEST
Measure the line pressure.
NOTICE:
Do the test at normal operation fluid temperature 50 − 80°C (122 − 176°F).
The line pressure test should always be carried out in pairs. One technician should observe
the conditions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
Be careful to prevent SST’s hose from interfering with the exhaust pipe.
(1) Warm up the fluid.
(2) Remove the test plug on the transmission case right side and connect SST.
(See page AT−26 and AT−33 for the location to connect SST)
SST 09992−00094 (09992−00150, 09992−00270)
(3) Fully apply the parking brake and chock the 4 wheels.
(4) Start the engine and check idling speed.
(5) Keep your left foot pressed firmly on the brake pedal and shift into D position.
(6) Measure the line pressure when the engine is idling.
(7) Depress the accelerator pedal all the way down. Quickly read the highest line pressure when
engine speed reaches stall speed.
NOTICE:
Release the accelerator pedal and stop test if the rear wheels begin to rotate before the engine speed
reaches specified stall speed.
(8) In the same manner, do the test in R position.
Specified line pressure:

If the measured pressures are not up to specified values, recheck the throttle cable adjustment and retest.
Evaluation
ProblemPossible cause
If the measured value at all positions are higher
Throttle cable out of adjustment
Throttle valve defective
Regulator valve defective
If the measured value at all positions are lower
Throttle cable out of adjustment
Throttle valve defective

Forward clutch defective
If pressure is low in the R position only
