Low ＆ Reverse Brake is released When the vehicle speed over the 5MPH(7km/h).

Stall test procedure in D1 and reason
Procedure
1.

Warm up the engine.

After positioning the select lever in "D", depress the foot brake pedal fully after that, depress the accelerator
pedal to the maximum.
* The slippage of 1st gear operating parts can be detected by stall test in D

Reason for stall test
1.

If there is no mechanical defaults in A/T, all slippages occurrs in torque converter.

Therefore, engine revolution is output, but input and output speed revolution must be "zero" due to wheel’s lock.

If 1st gear operating part has faults, input speed revolution will be out of specification.

If output speed revolution is output. It means that the foot brake force is not applied fully. Remeasuring is re-
quired.

Is "STALL TEST " within specification?

YES

▶ Go to "Signal circuit inspection" procedure.

▶ Go to "Component inspection" procedure.

CAUTION

Do not let anybody stand in front of or behind the vehicle while this test is being carried out.

Check the A/T fluid level and temperature and the engine coolant temperature.

• Fluid level : At the hot mark on the oil level gauge.
• Fluid temperature : 176 F~ 212 F (80~100 C).
• Engine coolant temperature : 176 F~ 212 F (80~100 C).

Chock both rear wheel(left and right).

Pull the parking brake lever on with the brake pedal fully depressed.

The throttle should not be left fully open for more than eight second.

If stall test is being performed more than once, move the selector lever to ’N’ and run the engine at 1000
RPM to allow the transaxle fluid to cool prior to subsequent tests.

Does "INPUT ＆ OUTPUT SPEED SENSOR" within specifications?

YES

▶ Go to "Component Inspection" procedure.

▶ Check for electrical noise of circuit in INPUT ＆OUTPUT SPEED SENSOR or Replace INPUT ＆ OUTPUT SPEED
SENSOR. Repair as necessary and Go to "Verification of Vehicle Repair" procedure.
