TRANSMISSION FLUID CHECK

M1231021400179

1. Drive the vehicle until the transmission fluid temperature 

rises to the normal operating temperature [70 

− 80°C (158 − 

176

°F)].

NOTE: The transmission fluid temperature is measured with 
scan tool MB991958 (M.U.T.-III sub assembly).
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. Tran-
saxle overhaul and cooler line flushing may be necessary.

5. Check transmission fluid level is at the "H" mark on the 

dipstick. If the transmission fluid level is less than this, add 
DIA QUEEN ATF- J3 until the level reaches the "H" 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 to form bubbles. If the transmission fluid level is too 
high, rotating components inside the transaxle 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.
NOTE: In either case, air bubbles can interfere with normal 
valve, clutch, and brake operation. Also, foaming can cause 
transmission fluid to escape from the transaxle vent 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 transaxle.

•

When overhauling the transaxle.

•

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