So last November I was driving home when suddenly my car downshifted really hard and then wouldn’t move at all I turned it off and back on then got it to move again it did it twice before I ended up having to park it I got it towed and I scanned it and it came back a solenoid issue so I waited till about April and bought every solenoid and I changed them about a month ago and I also had a bunch of other work done to it too well today I finally filled it all up with fluids and it won’t go into gear at all the rpms change when I do go into reverse and drive but it won’t move at all does anybody know what this could be?
