many chrysler mtx's call for atf, but, and this is a big but, it is used to save money. The synchros will wear faster with it, and it will not shift as easy as the correct mopar fluid ($16 a quart) or mobil one 10w30 high mileage. Its very important to use mobil one 10w30 high mileage if you choose to use engine oil, especially in a neon, as the synchros are made of a material called fiberide, and according to oil analysis, only those 2 oils (the mopar stuff and mobil one stuff) have enough zdp to prevent premature wear to the synchros. Mobil one is 99% the same as the mopar stuff.

ive used both royal purple and penzoil synchromesh oils, and neither shifted as smooth as the correct mopar fluid or the mobil one oil
