42. TRANSMISSION, TRANSFER,
DIFFERENTIAL OIL INSPECTION
AND CHANGE
[I nspectionl
1) Inspect transmission case, transfer case and
differential housing for evidence of oil leakage.
Repair leaky point if any.
2) Make sure that the car is placed level for oil
level check.
3) Remove each level plug of transmission,
transfer and differential (front and rear).
In any of these cases, oil level can be checked
roughly by means of level plug hole. That is,
,if oil flows out of level plug hole or if oil
level is found up to hole when level plug is
removed, oil is properly filled.
If oil is found insufficient, pour specified
amount of specified oil as given in the below
table.
[Change]
Oil change procedure is as follows.
Place the car level and drain oil by removing
drain plug. Pour specified amount of specified
oil as in the below table and tighten drain plug
and filler plug to specified torque.
It is highly recommended to use SAE 75W-90
gear oil.
