It is recommended that you take it to test, some soleniodes fail electrically. Then work on the diagnostic results.
Be sure to put oil specifically for the vehicle brand. ATF Chrysler, Mercon Ford, Dexron Chevrolet; the classification that is most close to the letter Z is much better.
Also check the amount of waste that is deposited at the bottom of the carter, if you see a lot of dust or cover you already have record wear.
I have the doubt of cafe.
