Yep, if anyone is unsure if they have the 242 T-case, just look at the plastic bezel around your shifters and if it says Selec-Trac, then you can use ATF+4. If it says anything else, you should ONLY use the special "Mopar 245/247/249" fluid (that's actually what it's called). Part #05016796AC. You can get it from the dealer easily.
