However, a crucial note: Many automatic transmissions in 1995 Mustangs *do not* have a dipstick. If you can't locate a dipstick, your Mustang likely uses a sealed transmission system. Adding transmission fluid to a sealed system incorrectly can cause serious damage. In that case, you should consult a repair manual specific to your Mustang's transmission type (e.g., AOD, 4R70W) or take it to a qualified mechanic.
Before attempting to add fluid, consult your owner's manual. It will confirm the location of the dipstick (if present) and the correct type of transmission fluid to use.
