BASIC INSPECTION
1.
CHECK FLUID LEVEL
(a)
Using SST, create a short–circuit between terminals TC
and CG of the DLC3.
SST
09843–18040
(b)
Start the engine and run at idle.
The A/C switch must be turned off.
On models with active height control suspension &
adaptive variable suspension, turn the height con-
trol switch off.
(c)
Slowly move the shift lever through all positions from P to
L, and move it back to the P position.
(d)
Switch to the fluid temperature detection mode.
Move the shift lever from the N to the D position, or from
D to N, within 1.5 seconds. (Repeat this operation for 6 se-
conds or more.)
OK: The A/T OIL TEMP warning light comes on for 2
seconds and then goes off.
(e)
Return the shift lever to the P position and disconnect ter-
minals TC and CG.
(f)
Idle the engine to raise oil temperature.
(g)
Lift up the vehicle immediately after the meter indicator
light (ATF temperature warning light) comes on.
The A/T OIL TEMP warning light indicates the ATF
temperature according to the following table.

(h)
Remove the overflow plug and check the fluid level.
Standard:
When ATF overflows
ATF 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:
”Overflow” 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 ”overflow”.
(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.

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

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.
