(h) Remove the overflow plug and check the fluid level.
Standard:
When ATF overflowsATF level is higher than specification
(Go to step (k))
When ATF does not overflow
ATF level is equal to or lower than
specification
(Go to step (i))
HINT:

ºOverflowº indicates the condition under which ATF
drains out from the overflow tube.

The capacity of the overflow tube is approximately 3 cc.
If the amount of drained ATF is little, only the fluid remain-
ing in the tube has drained out. This condition is not con-
sidered as ºoverflowº.
(i) Remove the refill plug.
(j) Add ATF through the refill hole until it flows out from the
overflow hole.
Fluid type: Toyota genuine ATF WS
(k) When the draining ATF has become a trickle, install the
overflow plug with a new gasket.
(l) Install the refill plug if removed.
(m) Lower the vehicle.
(n) Turn the ignition switch off to stop the engine.
2. CHECK FLUID CONDITION
If the fluid smells burnt or is black, replace it (see step 6).
3. INSPECT AND ADJUST SHIFT LEVER POSITION
(a) 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 comes on in accordance with the shift lever position.
If the indicator and shift lever position do not match, carry out
the following adjustment procedures.
(1) Remove the nut and disconnect the shift control
cable from the control shaft lever.
(2) Move the control shaft fully rearward.
(3) Return the control shaft lever 2 notches to the N
position.
(4) Set the shift lever to the N position.
(5) Connect the shift control cable and temporarily
install the control shaft lever nut.
(6) While holding the shift lever lightly toward the R
position side, tighten the control shaft lever nut.
Torque: 14.5 N´m (148 kgf´cm, 11 ft´lbf)

(7) Start the engine and make sure that the vehicle
moves forward when shifting the lever from the N to
the D position and reverses when shifting it to the
R position.
4. INSPECT AND ADJUST PARK/NEUTRAL POSITION
(a) Check that the engine can be started when the shift lever
is in the N or P position, but cannot be started in other
positions.
If operation cannot be done as stated above, carry out the fol-
lowing adjustment procedures.

Loosen the park/neutral position switch bolt and set
the shift lever to the N position.

Align the groove with the neutral basic line.

Hold in position and tighten the bolt.
Torque:13 N´m (130 kgf´cm, 9 ft´lbf)

ROAD TEST
1. PROBLEM SYMPTOM CONFIRMATION
Based on the result of the customer problem analysis, try to reproduce the symptoms. If the problem is that
the transaxle does not shift up, shift down, or the shift point is too high or too low, conduct the following road
test referring to the automatic shift schedule and simulate the problem symptoms.
2. ROAD TEST
NOTICE:
Perform the test at the normal operating ATF (Automatic Transmission Fluid) temperature: 50 to 80°C
(122 to 176°F).
(a) D position test:
Shift into the D position and fully depress the accelerator pedal and check the following points. Check
up±shift operation.
(1) Check up±shift operation.
Check that 1 " 2, 2 " 3, 3 " 4 and 4 " 5th up±shifts take place, and that the shift points conform
to the automatic shift schedule (See page SS±24).
HINT:
5th Gear Up±shift Prohibition Control

Engine coolant temperature is 55 °C (131 °F) or less and vehicle speed is at 51 km/h (32 mph) or less.
4th Gear Up±shift Prohibition Control

Engine coolant temperature is 40 °C (104 °F) or less and vehicle speed is at 45 km/h (28 mph) or less.
5th Gear Lock±up Prohibition Control

Brake pedal is depressed.

Accelerator pedal is released.

Engine coolant temperature is 60 °C (140 °F) or less.
(2) Check for shift shock and slip.
Check for shock and slip at the 1 " 2, 2 " 3, 3 " 4 and 4 " 5th up±shifts.
(3) Check for abnormal noise and vibration.
Check for abnormal noise and vibration when up±shifting from 1 " 2, 2 " 3, 3 " 4 and 4 " 5
while driving with the shift lever in the D position, and check while driving in the lock±up condition.
HINT:
The check for the cause of abnormal noise and vibration must be done thoroughly as it could also be due
to loss of balance in the differential, torque converter clutch, etc.
(4) Check kick±down operation.
Check vehicle speeds when the 2nd to 1st, 3rd to 2nd, 4th to 3rd, and 5th to 4th kick±downs take
place while driving with the shift lever in the D position. Confirm that each speed is within the
applicable vehicle speed range indicated in the automatic shift schedule (See page SS±24).
(5) Check abnormal shock and slip at kick±down.
(6) Check the lock±up mechanism.

Drive in the D position (5th gear), at a steady speed (lock±up ON).

Lightly depress the accelerator pedal and check that the engine speed does not change
abruptly.
HINT:
If there is a big jump in engine speed, there is no lock±up.
