1.Drive the vehicle until
the A/T fluid temperature rises to the normal
operating temperature (70 - 80°C).
note |
The A/T fluid
temperature is measured with M.U.T.-III MB991958
(M.U.T.-III sub assembly).
|
note |
If it takes some amount of
time until the A/T fluid reaches its
normal operating temperature [70 -
80°C], check the A/T fluid
level by referring 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 A/T fluid.
note |
If the A/T 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.
Transmission overhaul and cooler line flushing
may be necessary.

5.Check A/T fluid
level is at the "H" mark on the dipstick. If the A/T
fluid level is less than this, add MITSUBISHI MOTORS GENUINE
ATF-J3 until the level reaches the "H" 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 to
form bubbles. If the A/T 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.
|
note |
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 transmission
vent where it may be mistaken for a
leak.
|
6.Securely insert the dipstick.
note |
The A/T fluid should
always be replaced under the following
conditions:
- When troubleshooting the
transmission.
- When overhauling the
transmission.
- When the A/T fluid is noticeably
dirty or burnt (driving under severe
conditions).
