(6) Adjust the oil amount as soon as reaching the starting temperature for oil adjustment procedures

(42°C (109.4°F)).

CAUTION:

Always be sure to adjust the ATF (overflow plug tightening) when at the proper temperature.

2) When shorting TC terminal circuit

(1) Short the data link connectors No. 13 and No. 4.

(2) Start the engine.

(3) Turn off all parts effecting an electrical load such as air conditioner, audio and lights.

(4) Operate the select lever in P   R   N   D   M   D   N   R   P to circulate ATF in the trans-

mission.

(5) Operate between N 

D within 1.5 sec. for a continuous 6 sec. or more to switch to the oil amount

adjustment mode. When the vehicle enters into oil amount adjustment mode, the upshift/downshift per-

mitted indicator lamps [ ]/[ ] in the combination meter light up simultaneously for 2 sec. and turn off

with no relation to the range position.

(6) After changing to oil pressure adjustment mode, switch to the “P” range.

(7) Remove the short of data link connectors No. 13 and No. 4.

(8) Check the status of the upshift/downshift permitted indicator lamps [ ]/[ ].

CAUTION:

If only the [ ] indicator lamp is illuminated or both [ ] and [ ] are illuminated simultaneously, stop

performing procedures and leave the vehicle in a cool location. Start over and repeat procedures

from Step (1) after the ATF temperature decreases to a point where only the downshift permitted in-

dicator lamp [ ] when shifting to oil amount adjustment mode.

(9) Adjust the oil as soon as the proper temperature for oil amount adjustment is reached.

CAUTION:

Always be sure to adjust the ATF when at the proper temperature.

3) Remove the overflow plug and check the oil amount when at the proper temperature for oil amount inspec-

tion.

• The oil amount is proper when fluid flows out of the overflow tube and then the flow of the fluid is thin.

• If fluid does not flow out of the overflow tube, fill through the refill hole until fluid flows out of the overflow

tube. The oil amount is proper when the flow of the fluid is thin.

4) Install the overflow plug using a new gasket.
CAUTION:

Tighten the overflow plug with the ATF temperature at (43°C — 47°C (109.4°F — 116.6°F) (indicator

lamps [ ] and [ ] are illuminated simultaneously).
Tightening torque:

20 N·m (2.1 kgf-m, 27.3 ft-lb)

5) Perform final tightening of the refill plug using a new O-ring.
Tightening torque:

39 N·m (4.0 kgf-m, 27.3 ft-lb)

6) Install engine under cover No. 2.
Tightening torque:

7.5 N·m (0.8 kgf-m, 5.5 ft-lb)

Check for leakage of gear oil from the rear differential.

B: REPLACEMENT

1. REAR DIFFERENTIAL

CAUTION:

• Gear oil is extremely hot just after driving. Be wary of receiving burns.

• Be careful not to spill the differential gear oil on exhaust pipe. If gear oil is spilled, wipe it off com-

pletely.

1) Lift up the vehicle.

2) Remove the filler plug and gasket using a 10-mm (0.39 in) socket hexagon wrench.

3) Remove the drain plug and gasket using a 10-mm (0.39 in) socket hexagon wrench.

4) Tighten the drain plug.
NOTE:

Use a new gasket.
Tightening torque:

49 N·m (5.0 kgf-m, 36.1 ft-lb)

5) Fill the differential carrier with gear oil to the bottom of filler plug.
NOTE:

Carefully refill gear oil while watching the level. Excessive or insufficient oil must be avoided.
Recommended gear oil:
