Checking the automatic transmission fluid level is a big pain. The procedure is described in the Crossfire Service Manual (available
here, see p. 21-294). First, you need a special dipstick. You can order one
here. Then, you'll need a code reader that can get the automatic transmission fluid temperature from the car's computer and a replacement dipstick tube cap (you have to break the old one to take it off). I don't have a code reader as I don't know which ones will give the transmission fluid temperature. If you find one, please post it.
