What type of oil should go into Chysler cars?

I know there is a certain type, just don't know which kind it is.What type of oil should go into Chysler cars?
The dealership I work for uses mobil oil. If you purchase trans fluid at a dealership you need atf+4, atf+3 is no longer available from a dealership and atf+4 is what it was replaced with.What type of oil should go into Chysler cars?
what year?...most newer Chrysler take ATF +4
Its very important to use the factory spec fluid marked MOPAR or you will pay dearly!
I use castrol GTX.Any oil will work but if you mean ';transmission fluid'; call the dealership and ask them.
If it is an 80's thru 90's, then ATF+3 is correct. You can get generic ATF+3 at most auto parts places. If it is newer, then it uses ATF+4, available at the dealer for about $7.50/qt.


I do not know the cutoff date where Chrysler went from ATF+3 to ATF+4. You could call and ask the dealer (that's free!).





ATF+4 is fully backward compatible with ATF+3, so you can't go wrong adding that.





Do NOT add any other type. Dexron kills Chrysler transmissions, as does Mercon, or any other type.
