A: INSPECTION
1) Check the level of the ATF.
Fluid
(1) Raise the ATF temperature to 60 to 80°C
(140 to 176°F) from 40 to 60°C (104 to 140°F)
(when cold) by driving a distance of 5 to 10 km (3
to 6 miles).
NOTE:
The level of ATF varies with fluid temperature. Pay
attention to the fluid temperature when checking oil
level.

(B) Upper level
(C) Lower level
(2) Make sure the vehicle is level. After select-
ing all positions (P, R, N,
D,
3, 2, l ) , set the se-
lect leveler in "P" range. Measure fluid level with
the engine idling.
NOTE:
After running, idle the engine for one or two min-
utes before measurement.
(3) If the fluid level is below the center between
upper and lower marks, add the recommended
ATF until the fluid level is found within the spec-
ified range (above the center between upper
and lower marks). When the transmission is hot,
the level should be above the center of upper
and lower marks, and when it is cold, the level
should be found below the center of these two
marks.
CAUTION:
Use care not to exceed the upper limit level.
ATF level varies with temperature. Remem-
ber that the addition of fluid to the upper limit
mark when the transmission is cold will result
in overfilling of fluid.
(4) Fluid temperature rising speed:
By idling the engine
Time for temperature rise to 60°C (140°F) with at-
mospheric temperature of 0°C (32°F): More than
25 minutes
<Reference>
Time for temperature rise to 30°C (86°F) with atmo-
spheric temperature of 0°C (32°F): Approx. 8 min-
utes
By running the vehicle
Time for temperature rise to 60°C (140°F) with at-
mospheric temperature of 0°C (32°F): More than
10 minutes
(5) Method for checking fluid level upon delivery
or at periodic inspection:
Check fluid level after a warm-up run of approx.
10 minutes. During the warm-up period, the au-
tomatic transmission functions can also be
checked.
2) Check the fluid for leaks.
Check for leaks in the transmission. If there are
leaks, it is necessary to repair or replace gasket, oil
seals, plugs or other parts.
B: REPLACEMENT
1) Lift-up the vehicle.
2) Drain the ATF completely.
CAUTION:
Directly after the engine has been running, the
ATF is hot. Be careful not to burn yourself.
NOTE:
Tighten the ATF drain plug after draining the ATF.
Tightening torque:
25 N-m (2.5 kgf-m, 18.1 ft-lb)
(A) Oil pan
(B) Drain plug
(C) Differential oil drain plug
3) Lower the vehicle.
