MECHANICAL SYSTEM TESTA6E571401030209Mechanical System Test Preparation
1. Apply the parking brake and use wheel chocks at the front and rear of the wheels.
2. Inspect the engine coolant. (See Section E.)
3. Inspect the engine oil. (See D–8 ENGINE OIL INSPECTION.)
4. Inspect the ATF levels. (See K2–79 Automatic Transaxle Fluid (ATF) Level Inspection.)
5. Inspect the idle speed and ignition timing in P position. (See F1–22 IDLE SPEED INSPECTION (4WD).)
Line Pressure Test
Note
•Line pressure cannot be measured on the JA5AX-EL automatic transaxle. Measure the low clutch
pressure in place of D and M range line pressures. Measure the reverse clutch pressure in place of R
position line pressure.
1. Engine idling.
(1) Perform mechanical system test preparation. (See K2–72 Mechanical System Test Preparation.)
Warning
•Removing the plug when the ATF is hot can be dangerous. Hot ATF can come out of the opening
and badly burn you. Before removing the square-head plug, allow the ATF to cool.
(2) Remove the plug and O-ring shown in the
figure.

Time Lag Test
1. Perform mechanical system test preparation. (See K2–72 Mechanical System Test Preparation.)
2. Start the engine.
3. Warm up the engine until the ATF temperature reaches 60—70°C {140—158°F}. Shift the selector lever from N
position to D range.
4. Use a stopwatch to measure the time it takes from shifting until engagement is felt. Take three measurements
for each test and average the results using the following formula.
Formula
Average time lag = (Time 1 + Time 2 + Time 3) / 3
5. Perform the test for the following shifts in the same manner.
•N position → P position
Time lag
N → D range ... approx. 0.5—1.0 second
N → R position ... approx. 0.6— 1.0 second

Automatic Transaxle Fluid (ATF) Level Inspection
Caution
•The ATF amount varies according to ATF's temperature. Therefore, when checking the ATF level or
replacing the ATF, use a thermometer to measure the temperature then adjust the ATF amount to
the specified level according to the specified temperature.
1. Park the vehicle on level ground.
2. Apply the parking brake and position wheel chocks securely to prevent the vehicle from rolling.
3. Adjust the length of the thermistor probe measure to the measure same as the dipstick and hold the probe with
a paper holder.
4. Insert into the filler tube and measure the
temperature.
5. Warm up the engine until the ATF reaches (60—
70 °C {140—158 °F}).
Caution
•Do not warm the transaxle by performing
stalls. This will damage the torque
converter.
Note
•In some cases it may be necessary to
inspect the ATF in the cool range 15—25 °C
{59—77 °F} before warming up the engine.
6. While depressing the brake pedal, shift the selector lever to each range (P—M), pausing momentarily in each
range.
7. Shift back to P position.
Note
•If the ATF level is too high or too low in hot condition, the following problems may be the cause.
8. While the engine is idling, verify that the ATF level
is in the HOT (65 °C {149 °F}) range. Add the
ATF specified type of, if necessary. (See K2–80
AUTOMATIC TRANSAXLE FLUID (ATF)

TRANSAXLE RANGE (TR) SWITCH INSPECTIONA6E571419440201
Note
•Input signals of the TR switch can be inspected with a WDS or equivalent. (See K2–90 TCM
INSPECTION.)
Inspection of Operation
1. Verify that the starter operates only with the ignition switch at the START position and the selector lever in P
and N positions.
•If not as specified, inspect for continuity at the TR switch. (See K2–80 Inspection of Continuity.)
2. Verify that the back-up lights illuminate when shifted to R position with the ignition switch at the ON position.
•If not as specified, inspect for continuity at the TR switch.
Inspection of Continuity
1. Disconnect the TR switch connector.
2. Inspect for continuity at the TR switch.
•If not as specified, adjust the TR switch, then
reinspect the TR switch. (See K2–83
