OIL CHANGE TIMING

Judging When to Change Transmission Oil by Oil Temperature

How to Check Transmission Oil Temperature History With CONSULT

1.

Turn ignition switch ON.

2.

Select “SHOW OIL TEMP HISTORY” in “Work support” in “TRANSMISSION”.

3.

Check transmission oil temperature frequency history to judge the timing of oil change.

TRANSMISSION OIL : Draining

INFOID:0000000009190112

1.

Remove the front diffuser. Refer to 

EXT-39, "FRONT DIFFUSER : Exploded View"

.

2.

Remove the heat insulator.

3.

Remove the filler plug (

).

Transmission oil status

Possible cause

Required operation

Varnish-like condition (It is as thick 
as varnish).

Clutch is burned.

Change the transmission oil. Check the trans-
mission assembly or any other parts on the ve-
hicle.

Milky or cloudy

Water is mixed in the fluid.
Example: 
• Inflow of engine coolant by internal explo-

sion of heat exchanger

• Inflow of water from breather by flood, etc.

Change the transmission oil. Check for flooded 
area.

A large amount of metal particles are 
contained in the fluid.

Sliding portions in the transmission assembly 
are excessively worn.

Change the transmission oil. Check the trans-
mission assembly operation for any malfunc-
tioning condition.

°

F)

Change both transmission oil and differential oil immediately.

Transmission oil temperature frequency history

Timing of oil chang

At least one count in “Oil Temperature Frequency 5”

Change both transmission oil and differential oil immediately.

At least one count in “Oil Temperature Frequency 4”

Change both transmission oil and differential oil ever 5,000 km 
(3,000 miles).

No count in both “Oil Temperature Frequency 4” and “Oil Temper-
ature Frequency 5”

Change both transmission oil and differential oil ever 60,000 km 
(36,000 miles).

TRANSMISSION OIL : Filling

INFOID:0000000009190113

REPLACEMENT/ADJUSTMENT PROCEDURE

NOTE:
Replace the filler plug gasket and drain plug with new ones after oil level adjustment.

1.

Remove the filler plug (

) and drain plug, and then fill with the

transmission oil until it leaks from the drain hole.

CAUTION:

• Always use the specified transmission oil. In addition,

always use the filler after cleaning. If use/mixed use/mis-
use of the transmission oil other than the specified brand
occurs, the original performance cannot be obtained or it
may cause serious malfunctions.

• Check that dust does not mix.
• Always use paper towels. Never use waste cloth.

2.

Install the filler plug and drain plug. Refer to 

TM-20, "Exploded View"

 (filler plug), 

TM-19, "Exploded View"

(drain plug).

3.

Start engine with shift position in P range and keep it until transmission system check is complete.

CAUTION:

• If the oil does not fully circulate in transmission oil line after engine start, it could cause an oil

flowing sound (such as hissing sound). Keep it at idle for several minutes in that case.

• Because of incomplete oil circuit in transmission oil line, a transmission warning light could illu-

minate at transmission system check. In this case, keep it at idle for several minutes, and then
restart the engine. 

4.

With depressing the brake pedal, shift the selectro lever to A range (wait for 5 seconds) 

→

 N range (wait

for 5 seconds) 

→

 R range (wait for 5 seconds) 

→

 P range.

5.

Stop the engine.

6.

Remove the filler plug and drain plug, and then fill with the transmission oil until it leaks from the drain
hole.

7.

Install the filler plug and drain plug. Refer to 

TM-20, "Exploded View"

 (filler plug), 

TM-19, "Exploded View"

(drain plug).

8.

Install the heat insulator.

9.

Start the engine and run it at idle. Run the engine until the oil temperature reaches 50

°

C (122

°

F) while

checking FLUID TEMP in “DATA MONITOR” of CONSULT.

10. With depressing the brake pedal, shift the selectro lever to A range (wait for 5 seconds) 

→

 N range (wait

for 5 seconds) 

→

 R range (wait for 5 seconds) 

→

 P range.

11. Stop the engine and wait for 5 minutes.
12. Remove the drain plug. Install the drain plug when the transmission oil begins to drip (1 drop/1 second).

Refer to 

TM-19, "Exploded View"

.

CAUTION:

• Perform from step 11 to step 12 within 25 minutes.
• Repeat the procedure from step 6 if the transmission oil does not leak from the drain hole.
