If the preload is less then specified, retighten the nut
13 N´m (130 kgf´cm, 9 ft´lbf) at a time until the speci-
fied preload is reached.
If the maximum torque is exceeded while retightening the
nut, replace the bearing spacer and repeat the preload
procedure.
Do not back off the nut to reduce the preload.
Maximum torque: 353 N´m (3,600 kgf´cm, 260 ft´lbf)
(e) If the preload is adjusted within specification, make a note
of it.
(f) Stroke the lock nut.

(b) Clearance the DTC.
The following actions will erase the DTC and freeze frame
data. Operating an OBD II scan tool (complying with SAE
J1978) or TOYOTA hand±held tester to erase the codes.
(See the OBD II scan tool's instruction book for operating
instructions.)
4. ROAD TEST
NOTICE:
Perform the test at normal operating ATF temperature 50 ± 80 °C (122 ± 176 °F).
(a) D position test
Shift into the D position and fully depress the accelerator pedal and and check the following points:
(1) Check up±shift operation.
1 " 2, 2 " 3 and 3 " O/D up±shifts take place, at the shift point shown in the automatic shift
schedule (See page SS±54).
HINT:

O/D Gear Up±shift Prohibition Control (1. Coolant temp. is 50 °C (122 °C) or less. 2. If there is a 10
km/h (6 mph) difference between the set cruise control speed and vehicle speed.)

O/D Gear Lock±up Prohibition Control (1. Brake pedal is depressed. 2. Coolant temp. is 50 °C
(122 °C) or less.)
(2) Check for shift shock and slip.
Check for shock and slip at the 1 " 2, 2 " 3 and 3 " O/D up±shifts.
(3) Check for abnormal noises and vibration.
Run at the D position lock±up or O/D gear and check for abnormal noises and vibration.
HINT:
The check for the cause of abnormal noises and vibration must be done very thoroughly as it could also be
due to loss of balance in the differential or torque converter clutch, etc.
(4) Check kick±down operation.
While running in the D position, 2nd, 3rd and O/D gears, check to see that the possible kick±down
vehicle speed limits for 2 " 1, 3 " 2 and O/D " 3 kick±downs conform to those indicated on
the automatic shift schedule (See page SS±54).
(5) Check abnormal shock and slip at kick±down.
(6) Check the lock±up mechanism.

Drive in D position, O/D gear, at a steady speed (lock±up ON) of about 75 km/h (47 mph).

Lightly depress the accelerator pedal and check that the engine speed does not change
abruptly.
If there is a big jump in 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 up±shift operation.
Check to see that the 1 " 2 up±shift takes place and that the shift point conforms to the automatic
shift schedule (See page SS±54).
HINT:
There is no O/D up±shift and lock±up in the 2 position.
