Hi All, Thanks for all the advice on the trans fluid. Like with many topics, we have limited data on how the new ATF fluids will actually perform in our old torqueflights. We also do not drive these beautiful Chrysler 300s as our everyday driver, so any detrimental effects may be stretched over 5-10-15 years. The best advice is to get the trans rebuilt by someone that knows them inside and out. The devil is in the details!

The operative word was detergents! The trannies in these beasts leak enough without any help from modern detergents to open up more leaks. A well functioning tranny with a well meaning owner would spend a small amount of money to change the fluid and that buys him/her a tranny rebuild. But it will be clean! Friction for crisp shifts should be the operative word. BTW, F replaced A and FA replaced F. The F stands for Ford and the A stands for A thus FA a dual use tranny fluid.
