Power from the input shaft is not transmitted to the output shaft because the clutches do not operate.
+ªPº position
Similar to the ªNº position, the clutches do not operate. The parking pawl engages with the parking gear
to mechanically hold the output shaft so that the power train is locked.

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.
6. Accelerate to wide open throttle gradually while applying foot
brake.
7. Quickly note the engine stall revolution and immediately
release throttle.
+During test, never hold throttle wide open for more than 5
seconds.
Stall revolution:
QG13DE 2,000 - 2,300 rpm
QG15DE 2,000 - 2,300 rpm
QG16DE 2,200 - 2,700 rpm
QG18DE 2,050 - 2,500 rpm

8. Move selector lever to ªNº position.
9. Cool off ATF.
+Run engine at idle for at least one minute.
10. Repeat steps 5 through 9 with selector lever in ª2º, ª1º and ªRº
positions.
JUDGEMENT OF STALL TESTNJAT0026S02The 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, follow the
WORK FLOW shown in AT-71 (Except for Euro-OBD) or AT-76
(EURO-OBD).
NOTE:
Stall revolution is too high in ªDº, ª2º or ª1º position:
+Slippage occurs in 1st gear but not in 2nd and 3rd gears. .....
Low one-way clutch slippage
+Slippage occurs in the following gears:

LINE PRESSURE TEST PROCEDURENJAT0027S021. Check A/T fluid and engine oil levels. If necessary, add fluid or
oil.
2. Drive vehicle for approx. 10 minutes or until engine oil and ATF
reach operating temperature.
ATF operating temperature:
50 - 80ÉC (122 - 176ÉF)

4. Set parking brake and block wheels.
+Continue to depress brake pedal fully while line pressure
test is being performed at stall speed.
SAT493G
5. Start engine and measure line pressure at idle and stall speed.
+When measuring line pressure at stall speed, follow the
stall test procedure.
Line pressure: Refer to SDS, AT-450.

DescriptionNJAT0102+The mechanical key interlock mechanism also operates as a shift lock:
With the key switch turned to ON, the selector lever cannot be shifted from ªPº (parking) to any other
position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from ªPº to any other position.
The key cannot be removed unless the selector lever is placed in ªPº.
+The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock
solenoid and by the operation of the rotator and slider located inside the key cylinder.
