AUTOMATIC TRANSMISSION FLUID CHECK
1. Drive the vehicle until t he fluid temperature rises to t he
normal temperature (70- 80_C).
2. Park the vehicle on a level surface.
3. Move the selector lever through all positions to fill t h e
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 oil level gauge, remove
the oil level gauge and check the condition of the fluid.
NOTE
If the fluid smells as if it is burning, it means that the
fluid has been contaminated by the particles from the
bushes and friction materials, a transmission overhaul
and flushing the cooler line may b e necessary.
5. Check that the fluid level is at the HOT mark on the
oil level gauge. If the fluid level is lower than this, pour
in more fluid until the level reaches the HOT mark.
Automatic transmission fluid:
Dia Queen ATF SP
II
or equivalent
NOTE
If the fluid level is low, the oil pump will draw in air along
with the fluid, which will cause bubbles to form inside
the hydraulic circuit. This will in turn cause t he hydraulic
pressure to drop, which will result in late shifting and
slipping of the clutches and brakes.
If there is too much fluid, the gears can churn it up into
foam and cause the same conditions that can occur with
low fluid levels.
In either case, air bubbles can cause overheating and
oxidation of the fluid which can interfere with normal valve,
clutch, an d brake operation. Foaming can also result in
fluid escaping from the transmission vent, in which case
it may be mistaken for a leak.
6. Securely insert the oil level gauge.
7. The fluid and oil filters should always be replaced in the
following conditions:
When troubleshooting the transmission
When overhauling the transmission
When the oil is noticeably dirty or deteriorates (driving
under the severe condition)
Furthermore, t he oil filters are special filters which are
only to be used for the automatic transmission.
