Fluid Inspection

AUTOMATIC TRANSAXLE FLUID CHECKING A/T FLUID LEVEL





1. Drive the vehicle until the A/T fluid temperature rises to the normal temperature [70 - 80°C (158 - 176°F)].

NOTE: The A/T fluid temperature is measured with scan tool MB99 1958.

NOTE: If it takes some amount of time until the A/T fluid reaches its normal operating temperature [70 - 80°C (158 - 176°F)],check the A/T fluid level by referring to the 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 A/T fluid, and then move the selector lever to the N position.
4. After wiping off any dirt from around the dipstick, remove the dipstick and check the condition of the A/T fluid.

NOTE: If the fluid smells as if it is burnt, it means that the A/T fluid has been contaminated by fine particles from the bushings and friction materials. A transaxle overhaul and cooler line flushing may be necessary.





5. Check that the A/T fluid level is at the HOT mark on the dipstick. If the A/T fluid level is lower than this, pour in more MITSUBISHI genuine ATF SP-III or equivalent until the level reaches the HOT mark.

NOTE: If the A/T fluid level is too low, the oil pump will draw in air along with the A/T fluid, which will cause bubbles to form. If the A/T 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. In either case, air bubbles can interfere with normal valve, clutch, and brake operation. Also, foaming can cause A/T fluid to escape from the transaxle vent where it may be mistaken for a leak.

6. Securely insert the dipstick.

NOTE: The A/T fluid should always be replaced when:
^ When overhauling the transaxle
^ When the oil is noticeably dirty or burnt (vehicle was driven under severe conditions)
