6. Accelerate to wide open throttle gradually while applying footbrake.
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-43, "
How to Perform Trouble Diagnosis for
Quick and Accurate Repair".
NOTE:
Stall revolution is too high in “D”, “2”, or “1” position:
• Slippage occurs in 1GR but not in 2GR and 3GR. ..... Low one-way clutch slippage
• Slippage occurs in the following gears:
1GR through 3GR in “D” position and engine brake functions with OD OFF. (OD OFF indicator lamp is on.)
1GR and 2GR in “2” position and engine brake functions with accelerator pedal released (fully closed throt-
tle)...... Forward clutch or forward one-way clutch slippage
Stall revolution is too high in “R” position:
• Engine brake does not function in “1” posit ion. ..... 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 con-
verter housing
CAUTION:
Be careful because automatic flui d temperature increases abnormally:
• Slippage occurs in 3GR and 4GR in “D” position. ..... High clutch slippage
• Slippage occurs in 2GR and 4GR in “D” position. ..... Brake band slippage
• Engine brake does not function in 2GR and 3GR in “D” pos ition, 2GR in “2” position, and 1GR 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 converter Stall revolution:

TROUBLE DIAGNOSIS
Location of line pressure test ports are shown in the figure.
•Always replace pressure plugs as they are self-sealing bolts.
Line Pressure Test Procedure
1. Check ATF and engine oil levels. If necessary, add ATF or
engine oil.
2. Drive vehicle for approx. 10 minutes or until engine oil and ATF reach operating temperature.
3. Install oil pressure gauge to corresponding line pressure test port.
4. Set parking brake and block wheels.
5. Start engine and measure line pressure at idle and stall speed. CAUTION:
• Keep the brake pedal pressed all the way down duringmeasurement.
• When measuring the line pressure at the stall speed, refer to "STALL TEST".

DESCRIPTION
• The purpose of the test is to det
ermine overall performance of A/T
and analyze causes of malfunctions.
• The road test consists of the following three parts:
1. Check before engine is started. Refer to AT- 5 6
.
2. Check at idle. Refer to AT- 5 6
.
3. Cruise test • Inspection all the item from Part 1 to Part 3. Refer to AT- 5 8
,
AT- 6 1
and AT- 6 2 .

JudgementSuspected parts
At idle Line 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 , "
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
speed Line pressure is low.
• Accelerator pedal position signal malfunction
• Line pressure solenoid valve sticking
• Short circuit of line pressure solenoid valve circuit
• Pressure regulator valve or plug sticking
• Pressure modifier valve sticking
• Pilot valve sticking

TROUBLE DIAGNOSIS
• Before road test, familiarize yourself with all test procedures anditems to check.
• Test all inspection items until the symptom is uncovered. Include
NG items in “Diagnostic Wo rksheet Chart”(Refer to AT- 4 3
). Per-
form a diagnosis of the NG items after the completion of all the
road tests.
