.
take a look here,..mind the temp of the atf
if I were you I would add 3q atf immidiately and worm a car
by 10-15 mile drive.
Then I would do the check according the table.
if you never checked atf oil it is not like engine oil i.e it is not so
obvious on the stick so you have to look closer to see the level.
ATF top-up?
cheers
