Troubleshooting
Engine Brake TestS7RS0B5104013
WARNING!
Before test, make sure that there is no vehicle behind so as to prevent rear-end collision.

1) While driving vehicle in 3rd gear of “D” range, shift select lever down to “2” range and check if engine brake
operates.
2) In the same way as in Step 1), check engine brake for operation when select lever is shifted down to “L” range.
3) Engine brake should operate in the test.
Troubleshooting
Stall TestS7RS0B5104014
This test is to check overall performance of automatic tr ansaxle and engine by measuring stall speed at “D” and “R”
ranges. Be sure to perform this test only when transaxle fluid is at normal operating temperature and its level is
between FULL and LOW marks.
CAUTION!
• Do not run engine at stall more than 5 seconds continuously, or fluid temperature may rise excessively high.
• After performing stall test, be su re to leave engine running at idle for longer than 1 minute before
another stall test.

1) Apply parking brake and block wheels.
2) Install tachometer.
3) Start engine with select lever shifted to “P” range.
4) Depress brake pedal fully.
5) Shift select lever to “D” range and depress accelerator pedal fully while watching tachometer. Read engine rpm quickly when it has become constant (stall speed).
6) Release accelerator pedal immediately after stall speed is checked.
7) In the same way, check stall speed in “R” range.
8) Stall speed should be withi n the following specification.
Engine stall speed
Standard: 2100 – 2400 rpm Condition Possible cause Correction / Reference Item
Operated gear is not
correct Faulty valve body component
Replace valve body assembly.
Faulty clutch or brake Inspect clutch and brake. If any parts are faulty,
replace them.
Condition Possible cause Correction / Reference Item
Failure to operate when
shifted down to “2” range Faulty valve body component
Replace valve body assembly.
Faulty O/D and 2nd coast brake Inspect. If NG, replace.
Failure to operate when
shifted down to “L” range Faulty valve body component
Replace valve body assembly.
Faulty 1st and reverse brake Inspect. If NG, replace.

Troubleshooting
Time Lag TestS7RS0B5104015
This test is to check conditions of clutch, brake and fluid pressure. “Time lag” means time elapsed since select lever is
shifted with engine idling till shock is felt.
1) With chocks placed before and behind front and rear wheels respectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from “N” to “D” range an d measure time from that moment till shock is felt.
4) Similarly measure time lag by shifting select lever from “N” to “R” range.
Gear shifting time lag
“N” → “D”: Less than 0.7 sec.
“N” → “R”: Less than 1.2 sec.
NOTE
• When repeating this test, be sure to wait at least one minute after select lever is shifted back to “N”
range.
• Engine should be warmed up fully for this test.
• Repeat test 3 times and take average of those data for final time lag data.

Condition Possible cause Correction / Reference Item
Lower than standard level
in both “D” and “R” range Engine output torque failure
Inspect and repair engine.
Faulty one-way clutch of torque
converter Replace torque converter.
Higher than standard
level in “D” range Malfunction of pressure control solenoid
valve (Low line pressure) Inspect. If NG, replace valve body assembly.
Faulty valve body component Replace valve body assembly.
Slippery forward clutch Inspect. If NG, replace.
Faulty one-way No.2 clutch Inspect. If NG, replace.
Leakage from “D” range fluid pressure
circuit Replace valve body assembly.
Higher than standard
level in “R” range Malfunction of pressure control solenoid
valve (Low line pressure) Inspect. If NG, replace valve body assembly.
Faulty valve body component Replace valve body assembly.
Slippery reverse clutch Inspect. If NG, replace.
Slippery 1st and reverse brake Inspect. If NG, replace.
Leakage from “R” range fluid pressure
circuit Replace valve body assembly.
Higher than standard
level in both “D” and “R”
range Malfunction of pressure control solenoid
valve (Low line pressure)
Inspect. If NG, replace valve body assembly.
Faulty valve body component Replace valve body assembly.
Clogged oil strainer Replace.
Faulty oil pump Inspect. If NG, replace.
Leakage from both “D” and “R” range
fluid pressure circuit Replace valve body assembly.
