ROAD TEST

This test is performed to make a proper judgment on the trouble symptom and check after completion of service work.
1.With the actual driving, check if there is any abnormality in transmission.
2.Check if there is any shift shock or abnormal sound.
3.Check the driving status with all the shift ranges including "R."
4.Perform the driving test with the reproduction condition which is investigated in the interview to check the failure occurrence.

P-RANGE TEST

1.Stop the vehicle completely on an upslope at the gradient of 5 to 10°, and then shift the selector lever to the "P" range. After that, release the foot brake gradually to check that the vehicle does not move.
2.With the status of the above Step 1, shift the selector lever from the "P" range to other ranges, and check that the vehicle moves.
3.Check the operation also on the downslope with the same manner.

SELECT TIME LAG

caution

Perform the test with the engine fully warmed up and the idling speed being stable.
On completion of the first test, when one minute or more has elapsed after the selector lever is returned from another position to the "N" range, perform the following tests.

1.Check the A/T fluid level and properties.
2.Check the transmission control cable and linkage.
3.Chock the front and rear wheels on a level surface, and depress the foot brake to stop the vehicle.
4.Start the engine, and shift the selector lever from the "N" range to the "D" range. At this time, measure the time from the lever selection to shock occurrence using a stop watch.
Standard value: - select time lag: 0.8 seconds
5.With the same manner, measure the select time from the "N" range to the "R" range.
Standard value: - select time lag: 0.8 seconds
If the measured value is abnormally large exceeding one second, the operating hydraulic pressure reduction and the A/T internal clutch slippage are assumed to have occurred.
