REASSEMBLY
1. A/T:
INSTALL OIL COOLER TO LOWER TANK
(a) Clean the O±ring contact surface of the lower tank and oil
cooler.
(b) Install a new O±rings (1) to the oil cooler (2).
(c) Install the oil cooler with the O±rings to the lower tank (3).
(d) Install the plate washers (4), and nuts (5). Torque the
nuts.
Torque: 8.3 N´m (85 kgf´cm, 74 in.´lbf)
(e) Install the pipe (6).
Torque: 14.7 N´m (150 kgf´cm, 11 ft´lbf)
2. INSPECT LOCK PLATE
Inspect the lock plate for damage.
HINT:
If the sides of the lock plate groove are deformed, reas-
sembly of the tank will be impossible.
Therefore, first correct any deformation with pliers or simi-
lar object. Water leakage will result if the bottom of the
lock plate groove is damaged or dented, Therefore, repair
or replace if necessary.
NOTICE:
The radiator can only be recaulked 2 times. After the 2nd
time, the radiator core must be replaced.
3. INSTALL NEW O±RINGS AND TANKS
(a) After checking that there are no foreign objects in the lock
plate groove, install the new O±ring without twisting it.
HINT:
When cleaning the lock plate groove, lightly rub it with sand pa-
per without scratching it.

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

(f) Inspect and adjust the shift lever position.
When shifting the shift lever from the N position to other
positions, check that the lever can be shifted smoothly
and accurately to each position and that the position indi-
cator is aligned with the correct position.
If the indicator is not aligned with the correct position, carry out
the following adjustment procedures.
(1) Loosen the nut on the shift lever.
(2) Push the control shaft fully rearward.
(3) Return the control shaft lever 2 notches to N posi-
tion.
(4) Set the shift lever to N position.
(5) While holding the shift lever lightly toward the R
position side, tighten the shift lever nut.
Torque: 13 N´m (130 kgf´cm, 9 ft´lbf)
(6) Start the engine and make sure that the vehicle
moves forward when shifting the lever from the N to
D position and reverses when shifting it to the R
position.
(g) Inspect and adjust the park/neutral position.
Check that the engine can be started with the shift lever
only in the N or P position, but not in other positions.
If it is not as stated above, carry out the following adjustment
procedures.
(1) Loosen the park/neutral position switch bolt and set
the shift lever to the N position.
(2) Align the groove and neutral basic line.
(3) Hold the switch in position and tighten the bolt.
Torque: 5.4 N´m (55 kgf´cm, 48 in´lbf)
For continuity inspection of the park/neutral position
switch, see page DI±424.
(h) Check the idle speed.
Idle speed : 750 ± 50 rpm
(In N position and air conditioner OFF)

6. MECHANICAL SYSTEM TESTS
(a) Measure the stall speed.
The object of this test is to check the overall performance of the transaxle and engine by measuring
the stall speeds in the D and R positions.
NOTICE:
Do the test at normal operating fluid temperature 50 ± 80 °C (122 ± 176 °F).
Do not continuously run this test for longer than 5 seconds.
To ensure safety, conduct this test in a wide, clear level area which provides good traction.
The stall test should always be carried out in pairs. One technician should observe the condi-
tions of wheels or wheel stoppers outside the vehicle while the other is doing the test.
(1) Chock the 4 wheels.
(2) Connect an OBD II scan tool or TOYOTA hand±held tester to DLC3.
(3) Fully apply the parking brake.
(4) Keep your left foot depressing firmly on the brake pedal.
(5) Start the engine.
(6) Shift into the D position. Press all the way down on the accelerator pedal with your right foot.
Quickly read the stall speed at this time.
Stall speed: 2,450 ± 150 rpm
(7) Do the same test in R position.
Stall speed: 2,450 ± 150 rpm
Evaluation:
ProblemPossible cause
(a) Stall speed low in D and R positions
Engine output may be insufficient
Stator one±way clutch is operating properly
HINT: If more than 600 rpm below the specified value, the torque
converter clutch could be faulty.
(b) Stall speed high in D position
Line pressure too low
Forward clutch slipping
No.2 one±way clutch not operating properly
O/D clutch slipping
(c) Stall speed high in R position
Line pressure too low
Direct clutch slipping
1st & reverse brake slipping
O/D clutch slipping
(d) Stall speed high in D and R positions
Line pressure too low
Improper fluid level
O/D one±way clutch not operating properly

DTC P0770 Shift Solenoid E Malfunction
(Shift Solenoid Valve SL)
SYSTEM DESCRIPTION
The ECM uses the signals from the Throttle position sensor,
Air±flow meter and Crankshaft position sensor to monitor the
engagement condition of the lock±up clutch.
Then the ECM compares the engagement condition of the
lock±up clutch with the lock±up schedule in the ECM memory
to detect mechanical trouble of the shift solenoid valve SL,
valve body, torque converter clutch or automatic transaxle
(clutch, brake or gear etc.).
DTC No.DTC Detecting ConditionTrouble Area
P0770
Lock±up does not occur when driving in the lock±up range
(normal driving at 80 km/h [50 mph]), or lock±up remains ON
in the lock±up OFF range.
(2 trip detection logic)
When lock±up is ON, clutch or brake slips or gear is broken.Shift solenoid valve SL is stuck open or closed
Valve body blocked up or stuck
Lock±up clutch
Automatic transaxle (clutch, brake or gear etc.)
INSPECTION PROCEDURE
1 Check solenoid valve SL operation.
PREPARATION:
(a) Remove the oil pan.
(b) Remove the shift solenoid valve SL.
CHECK:
(a) By applying 490 kPa (5 kgf/cm2, 71 psi) of compressed
air, check that the solenoid valve does not leak air.
(b) When battery positive voltage is supplied to the shift sole-
noid valve, check that the solenoid valve opens.
OK:
(a) Solenoid valve does not leak air.
(b) Solenoid valve opens.
NG Replace the solenoid valve SL.
