i need to know plz help me
where is the dip stick located to check the transmission fluid levels on this car on 2003 Cadillac Seville STS
The transmission fluid dipstick in your 2003 Cadillac Seville should be located just bellow the air cleaner housing - kind of hard to see with all the hoses in the way.
It unscrews. But is a little bit of a trouble to get to it. You may find it easier to remove the air filter and housing.
