determine what kind of transmission
fluid to use.
Using a funnel, add fluid down the
transmission dipstick tube only after
checking the transmission fluid
while it is hot. A cold check is used
only as a reference. If the fluid level
is low, add only enough of the
proper fluid to bring the level up to
the HOT area for a hot check.
It does not take much fluid,
generally less than 0.5 Liter (1 Pint).
Do not overfill.

When to Check and Change
Automatic Transmission Fluid
It is usually not necessary to
check the transmission fluid level.
The only reason for fluid loss is a
transmission leak or overheated
transmission. If a small leak is
suspected, then use the following
checking procedures to check the
fluid level. However, if there is a
large leak, then it may be necessary
to have the vehicle towed to a
dealer service department and have
it repaired before driving the vehicle
further.
