The other day was driving on the freeway about 75 MPH then all the sudden the car felt like it slammed on the brakes on its own and actually engine sounded like as if downshifted into first but it was in D4. it’s a automatic transmission after it happen hit the brakes then gas again then it went back to normal.
second time it has happened. could it be the shift solenoid???

Okay, so best bet is to replace both of them. I believe it has 2 top and bottom.
