TRANSMISSION FLUID CHECK

M1231103700029

Required Special Tool:

• MB991958: Scan Tool (MUT-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: MUT-III USB Cable

• MB991911: MUT-III Main Harness B

1. Drive the vehicle until the transmission fluid temperature 

rises to the normal temperature [70 

− 80°C (158 − 176°F)].

NOTE: The transmission fluid temperature is measured with 
scan tool MB991958.
NOTE: If it takes some amount of time until the transmission 
fluid reaches its normal operating temperature [70 

−

 80

°

C 

(158 

−

 176

°

F)], check the transmission fluid level by refer-

ring to the left diagram.

2. Park the vehicle on a level surface.
3. Move the selector lever through all positions to fill the torque 

converter and the hydraulic circuits with fluid, and then move 
the selector lever to the "N" position.

4. After wiping off any dirt around the dipstick, remove the 

dipstick and check the condition of the transmission fluid.
NOTE: If the transmission fluid smells as if it is burnt, it 
means that the transmission fluid has been contaminated by 
fine particles from the bushings and friction materials. A 
transmission overhaul and cooler line flushing may be nec-
essary.

5. Check that the transmission fluid level is at the "HOT" mark 

on the dipstick. If the transmission fluid level is less than 
this, add DIAMOND ATF SP III transmission fluid until the 
level reaches the "HOT" mark.
NOTE: If the transmission fluid level is too low, the oil pump 
will draw in air along with the transmission fluid, which will 
cause bubbles to form. If the transmission fluid level is too 
high, rotating components inside the transmission will churn 
the fluid and air into a foamy liquid. Both conditions (level 
too low or too high) will cause the hydraulic pressure to 
drop, which will result in late shifting and slipping of the 
clutches and brakes.
In either case, air bubbles can interfere with normal valve, 
clutch, and brake operation. Also, foaming can cause trans-
mission fluid to escape from the transmission vents where it 
may be mistaken for a leak.

6. Securely insert the dipstick.

NOTE: The transmission fluid should always be replaced 
under the following conditions:

.

•

When troubleshooting the transmission

•

When overhauling the transmission

•

When the transmission fluid is noticeably dirty or burnt 
(driving under severe conditions)

TRANSMISSION FLUID CHANGE

M1231104100020

Required Special Tool:

• MB991958: Scan Tool (MUT-III Sub Assembly)

• MB991824: V.C.I.

• MB991827: MUT-III USB Cable

• MB991911: MUT-III Main Harness B

If you have an transmission fluid changer, use it to replace the 
transmission fluid. If you do not have an transmission fluid 
changer, replace the transmission fluid by the following proce-
dure.
1. Disconnect the hose shown in the illustration which 

connects the transmission and the oil cooler (inside the 
radiator). Place a container under the hose to collect the 
discharge.

CAUTION

The engine should be stopped within one minute after it is 
started. If all the transmission fluid has drained out before 
then, the engine should be stopped at that point. 
2. Start the engine and let the transmission fluid drain out.

(Running conditions: "N" range with engine idling.)

Discharge volume: Approximately 4.0 dm

 (4.2 quarts)

3. Remove the drain plug from the bottom of the transmission 

case to drain the transmission fluid.

Discharge volume: Approximately 2.0 dm

3

 (2.1 quarts)

4. Install the drain plug with a new gasket, and tighten it to the 

specified torque.

Tightening torque: 39 N

⋅m (29 ft-lb)

CAUTION

Stop pouring if the full volume of transmission fluid can 
not be added.
5. Add new transmission fluid (DIAMOND ATF SP III) through 

the oil filter tube.

Adding volume: Approximately 6.0 dm

3

 (6.3 quarts)

6. Repeat the procedure in Step 2. (to pump out the rest of the 

contaminated transmission fluid)

7. Add new transmission fluid (DIAMOND ATF SP III) through 

the oil filler tube. 

Adding volume: Approximately 4.0 dm

3

 (4.2 quarts)

NOTE: Check for contamination or a burnt odor. If the trans-
mission fluid is still contaminated or burnt, repeat Steps 6 
and 7 before proceeding to Step 8.

8. Reconnect the hose which was disconnected in step 1 

above, and firmly replace the dipstick.

9. Start the engine and run it at idle for one to two minutes.
10.Move the selector lever through all positions, and then move 

it to the "N" position.

11.Check that the transmission fluid level is at the "COLD" 

mark on the dipstick. If the level is less than this, add 
transmission fluid.

12.Drive the vehicle until the transmission fluid temperature 

rises to the normal operating temperature [70 

− 80°C (158 − 

176

°F)], and then check the transmission fluid level again. 

The transmission fluid level must be at the "HOT" mark.
NOTE: The transmission fluid temperature is measured with 
scan tool MB991958.
NOTE: The "COLD" level is for reference only; the "HOT" 
level should be regarded as the standard level.
