A/T FLUID CHECK
Fluid Leakage and Fluid Level Check
Check fluid leakage and check the fluid level. Refer to AT-16, "Checking A/T Fluid" .
Fluid Condition Check
Check the A/T fluid condition.
STALL TEST
Stall Test Procedure
1. Check ATF and engine oil levels. If necessary, add ATF and
engine oil.
2. Drive vehicle for approximately 10 minutes or until ATF and
engine oil reach operating temperature.
3. Set parking brake and block wheels.
4. Install a tachometer where it can be seen by driver during test.

It is good practice to mark the point of specified engine
rpm on indicator.
5. Start engine, apply foot brake, and place selector lever in “D”
position.
Fluid status Conceivable Cause Required Operation

6. Accelerate to wide open throttle gradually while applying foot
brake.
7. Quickly note the engine stall revolution and immediately release
throttle.
CAUTION:
Do not hold down the accelerator pedal for more than 5 sec-
onds during this test.
8. Move selector lever to “N” position.
9. Cool off ATF.
CAUTION:
Run the engine at idle for at least 1 minute.
10. Repeat steps 6 through 9 with selector lever in “2”, “1” and “R”
positions.
Judgement of Stall Test
The test result and possible damaged components relating to each result are shown in the illustrations on next
page.
In order to pinpoint the possible damaged components, refer to AT-46, "
Work Flow Chart" .
NOTE:
Stall revolution is too high in “D”, “2”, or “1” position:

Slippage occurs in 1st gear but not in 2nd and 3rd gears. ..... Low one-way clutch slippage

Slippage occurs in the following gears:
1st through 3rd gears in “D” position and engine brake functions with OD OFF. (OD OFF indicator lamp is
on.)
1st and 2nd gears in “2” position and engine brake functions with accelerator pedal released (fully closed
throttle)...... Forward clutch or forward one-way clutch slippage
Stall revolution is too high in “R” position:

Engine brake does not function in “1” position. ..... Low & reverse brake slippage

Engine brake functions in “1” position. ..... Reverse clutch slippage
Stall revolution within specifications:

Vehicle does not achieve speed of more than 80 km/h (50 MPH). ..... One-way clutch seizure in torque
converter housing
CAUTION:
Be careful because automatic fluid temperature increases abnormally:

Slippage occurs in 3rd and 4th gears in “D” position. ..... High clutch slippage

Slippage occurs in 2nd and 4th gears in “D” position. ..... Brake band slippage

Engine brake does not function in 2nd and 3rd gears in “D” position, 2nd gear in “2” position, and 1st gear
in “1” position with OD OFF. (OD OFF indicator lamp is on.) ..... Overrun clutch slippage
Stall revolution less than specifications:

Poor acceleration during starts. ..... One-way clutch seizure in torque converterStall revolution: 2,300 - 2,750 rpm

5. Start engine and measure line pressure at idle and stall speed.
CAUTION:

Keep the brake pedal pressed all the way down during
measurement.

When measuring the line pressure at the stall speed,
refer to AT-53, "
STALL TEST" .
Line Pressure
Judgement of Line Pressure Test

Engine speedLine pressure [kPa (kg/cm2 , psi)]

Stall speed 1,173 (12.0, 170) 1,825 (18.6, 265)
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 AT - 2 2 , "
CLUTCH AND BAND CHART" .
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
