1.Drive the vehicle until
the A/T fluid temperature reaches the normal temperature (70
- 80°C)
| note |
Measure A/T fluid temperature
using M.U.T.-III.
|
| note |
Check the oil level referring
to the characteristics chart shown at left if it
takes some
time to reach the normal operation temperature
of A/T fluid (70 - 80°C).
|
2.Park the vehicle on a level
surface.
3.Move the selector lever to all
positions to fully charge the torque converter and
the fluid lines with A/T fluid, and then move the selector
lever to the N position.
4.After wiping away any
dirt from around the oil level gauge, pull out the oil level
gauge and check the level of A/T fluid.
| note |
If the A/T fluid has a burnt
smell, or if it has become very contaminated or
dirty, it
means that the A/T fluid has become contaminated
by minute particles form bushings (metal) or
worn parts. In such a case, the transmission
needs to be overhauled and the A/T fluid cooler
line needs to be flushed out.

5.Check that the A/T fluid
level is between the HOT marks on the oil level gauge. If
the
A/T fluid level is too low, add more A/T fluid until the
level reaches between the HOT marks.
Automatic
transmission fluid: DIA QUEEN ATF SP III
| note |
If the A/T fluid level is too
low, the oil pump draws air into the system
along with the
A/T fluid, and air bubbles will thus from in the
fluid circuit. This will cause a drop in fluid
pressure
and cause the shift points to change and the
clutches and brakes to slip. If the A/T fluid
level
is too high, the gear will churn the A/T fluid
and cause bubbles to develop, which can then
cause the same problems as when the A/T fluid is
too low. In either case, the air bubbles can
cause
overheating and oxidation of the A/T fluid, and
also prevent the valves, clutches and brakes
from operating normally. In addition, if bubbles
develop in the A/T fluid, the A/T fluid can
overflow from the transmission vent holes and be
mistaken for leaks.

6.Securely re-insert the oil level
gauge.
