Road Test

ROAD TEST

NOTE: Conduct the test at the normal operating temperature of the ATF: 50 - 80 °C (122 - 176 °F).

a. D position test:
Shift into the D position and fully depress the accelerator pedal and check the following points:

1. Check the up-shift operation.
Check to see if the 1 -> 2, 2 -> 3 and 3 -> 0/D up-shifts take place and if the shift points conform to the automatic shift schedule.

HINT:
- O/D Gear Up-shift Prohibition Control (1. Coolant temperature is 60 °C (140 °F) or less. 2. If there is a 10 km/h (6 mph) difference between the set cruise control speed and the actual vehicle speed.)
- O/D Gear Lock-up Prohibition Control (1. Brake pedal is depressed. 2. Coolant temperature is 60 °C (140 °F) or less.)

2. Check for shock and slip when shifting.
Check for shock and slip at the 1 -> 2, 2 -> 3 and 3 -> 0/D up-shifts.

3. Check for abnormal noises and vibration.
Drive the D position lock-up or the 0/D gear and check for abnormal noises and vibration.

HINT: The cause of abnormal noises and vibration must be checked very thoroughly, as it could also cause loss of balance in the differential torque converter clutch, etc.

4. Check the kick-down operation.
While during in the D position, 2nd, 3rd and 0/D gears, check to see if the 2 -> 1, 3 -> 2 and O/D -> 3 kick-downs conform to the automatic shift schedule.

5. Check for abnormal shock and slip at the kick-downs.
6. Check the lock-up mechanism.
- Drive in the D position, 0/D gear, at a steady speed (lock-up ON) of about 60 km/h (37 mph).
- Lightly depress the accelerator pedal and check that the engine speed does not change abruptly.

If there is a big jump in the engine speed, there is no lock-up.

b. 2 position test:
Shift into the 2 position and fully depress the accelerator pedal and check the following points:

1. Check the up-shift operation.
Check to see if the 1 -> 2 up-shift takes place and if the shift point conforms to the automatic shift schedule.

HINT: There is no 0/D up-shift and lock-up in the 2 position.

2. Check the engine braking.
While driving in the 2 position, 2nd gear, release the accelerator pedal and check the engine braking effect.

3. Check for abnormal noises during acceleration and deceleration, and for shock at the up-shift and the down-shift.

c. L position test:
Shift into the L position and fully depress the accelerator pedal and check the following points:

1. Check no up-shift.
While driving in the L position, check that there is no up-shift to the 2nd gear.

2. Check the engine braking.
While driving in the L position, release the accelerator pedal and check the engine braking effect.

3. Check for abnormal noises during acceleration and deceleration.

d. R position test:
Shift into the R position and fully depress the accelerator pedal and check for slipping.

CAUTION: Before conducting this test, ensure that the test area is free from people and obstruction.

e. P position test:
Stop the vehicle on a grade (more than 5°), shift into the P position, and release the parking brake. Then, check to see if the parking lock pawl holds the vehicle in place.
