first don't do it ,,unless u r having a problem with the tranny also ,unless your fluid is black, or burnt ,, and if u still want,,to but ,not need to change it , the only drain is by dropping the pan ,,catch as much as u can strain it clean it and put it back, (if it is not black or burnt,, ) you can only remove 30 to 40% of the old fluid and some times when new fluid is mixed with old fluid the tranny will slip. get a dip stick, your car does not have one ,dipstick tube yes dip stick no look at the color .
the transmission is a sealed unit it does not get dirty and only needs changing if there is a problem I have not changed my tranny fluid in a transmission in 20 years owning over 100 different cars, my last crossfire before installing a V8 and performance tranny had 174000 miles with out changing the fluid and no tranny problems.
