Automatic Transmission Fluid
When to Check and Change:
A good time to check your automatic transmission fluid level
is
when the
engine oil is changed. Refer to the Maintenance Schedule to determine when
to change your fluid. See "Scheduled Maintenance Services" in the Index.
How to Check:
Because this operation can be a little difficult, you may choose to have this
done at a dealership Service Department.
If you do it yourself, be sure to follow all the instructions, here, or you 'could
get a false reading on the dipstick.
